Kemijska složenost organskih onečišćujućih tvari u prirodnim vodama, poput
lijekova, agrokemikalija i boja, zahtijeva primjenu novih i naprednijih načina njihova
uklanjanja iz voda u odnosu na konvencionalne metode njihova pročišćavanja.
Jedna od takvih metoda je fotokatalitička razgradnja. U ovom radu su opisani
mehanizmi razgradnje štetnih organskih spojeva pomoću poluprovodničkih
materijala s aktivnim fotokatalitičkim svojstvima uz djelovanje UV ili vidljivog
zračenja te metode i odabir komponenata za pripravu najnovijih fotokatalizatora,
njihova stabilnost kao i učinkovitost uklanjanja organskih onečišćujućih tvari. U
radu su također opisane prednosti i nedostatci fotokatalitičkih metoda, kao i
smjernice za buduća istraživanja u ovom području.

The chemical complexity of organic contaminants (drugs, agrochemicals and
dyes) requires new more advanced ways to remove them from water compared
to the conventional treatment methods used. One such method is photocatalytic
degradation. In this paper, the mechanism of degradation of harmful organic
compounds using semiconductor materials with photocatalytically active
properties in the presence of UV or visible radiation will be explained. Methods
and selection of components for the preparation of the latest developed
photocatalysts, their stability as well as the percentage of contaminant removal
will be discussed. The discussion will also cover the advantages and drawbacks
of photocatalytic methods, as well as future research in this area.
Keywords: photocatalysis, organic water contaminants, dyes, drugs, pesticides

Podzemna voda je jedinstven i nezamjenjiv prirodni resurs ograničenih količina i
neravnomjerne prostorne i vremenske raspodjele. Za potrebe javne vodoopskrbe
godišnje se zahvaća 435 milijuna m3 podzemne vode na 467 vodocrpilišta, što je
91,2 % ukupno zahvaćenih količina. Za ostale potrebe zahvaća se oko 154
milijuna m3 podzemne vode na 2913 vodozahvata. Za potrebe izrade planova
upravljanja vodnim područjima određena su osnovna i grupirana tijela podzemne
vode, uspostavljen monitoring podzemnih voda, donesena je Uredba o standardu
kakvoće voda, analizirani pritisci i određeno kemijsko i količinsko stanje tijela
podzemne vode. Na vodnom području rijeke Dunav je izdvojeno 20, a na
Jadranskom vodnom području 13 grupiranih vodnih tijela podzemne vode. Ocjena
kemijskog stanja navedenih vodnih tjela provedena je primjenom sljedećih testova
„Zaslanjenje ili druga intruzija“, „Površinske vode, „Kopneni ekosustavi ovisni o
podzemnim vodama“, „Zaštitne zone izvorišta vode za piće (DWPA)“ i „Opća
ocjena kakvoće“. Za količinsko stanje podzemnih voda korišteni su testovi
„Zaslanjenja ili druga intruzija“, „Površinske vode“, „Kopneni ekosustavi ovisni o
podzemnim vodama“ i „Bilanca voda“. Navedenim testovima utvrđeno je dobro
kemijsko stanje svih podzemnih voda u panonskom dijelu Hrvatske, osim na
Varaždinskom području, dok na krškom području su samo tijela Južna Istra i
Boljkovac-Golubinka u lošem stanju. Na Dunavskom vodnom području sva tijela
podzemnih voda su u dobrom količinskom stanju, a na Jadranskom vodnom
području samo je tijelo Bokanjac-Boljkovac u lošem stanju.

*zpekas@voda.hr
Groundwater is a unique and irreplaceable natural resource of limited quantities
unevenly distributed in space and time. For the needs of the public water supply,
435 million m3 of groundwater is abstracted annually at 467 water abstraction
sites, accounting for 91.2% of the total abstracted quantities. For other needs,
around 154 million m3 of groundwater is abstracted annually at 2,913 water
abstraction sites. In order to prepare the river basin management plans, basic
groundwater bodies were designated and grouped, groundwater monitoring was
established, the Regulation on water quality standard was adopted, pressures
were analyzed, and the chemical and quantitative status of groundwater bodies
was identified. In the Danube and Adriatic river basin districts, 20 and 13 grouped
groundwater bodies respectively were designated. The following tests were used
for the assessment of groundwater chemical status: “Saline or other intrusions”,
“Surface water”, “Groundwater dependent terrestrial ecosystems”, “Drinking water
protection areas (DWPA)” and “General quality assessment”. The groundwater
quantitative status was assessed using the following tests: “Saline or other
intrusion”, “Surface water”, “Groundwater dependent terrestrial ecosystems”, and
“Water balance”. In the Pannonian part of Croatia, the chemical status of all water
bodies, except for the body “Varaždin area”, is assessed as good, and in the karst
region, only the bodies “Southern Istria” and “Boljkovac-Golubinka” has a poor
status. In the Danube river basin district, all the groundwater bodies have good
quantitative status, and in the Adriatic river basin district, only the body “Bokanjac-
Boljkovac” has a poor status.

Vodno gospodarstvo u Republici Hrvatskoj financira se iz više različitih izvora, a
najznačajnije je EU financiranje. Kroz Operativni program Konkurentnost i kohezija
2014.-2020. (OPKK) i Nacionalni plan oporavka i otpornosti 2021.-2026. (NPOO)
planiraju se financirati projekti ukupne vrijednosti 12,8 milijardi kuna, dok je za
Višegodišnji financijski okvir 2021.-2027. usuglašavanje u tijeku. EU sredstva dala
su novi zamah vodnome gospodarstvu te je od 2016. vidljivo povećanje
dostupnosti i poboljšanje kvalitete vode za ljudsku potrošnju, povećanje broja
stanovnika s mogućnošću priključenja na sustave javne odvodnje te povećanje
stupnja pročišćavanja otpadnih voda. Povećao se i broj točaka na kojima je
kvaliteta vode za kupanje izvrsna, i na moru i na kopnenim vodama. Unatoč
svemu, na Mediteranu se ispušta čak 60 % nepročišćenih otpadnih voda sa
značajnim pritiscima od turizma. S ciljem objedinjavanja poslova monitoringa
površinskih i podzemnih voda kao i drugih poslova neophodnih za dobro
upravljanje vodama i za izvještavanje Europske komisije o stanju voda u Republici
Hrvatskoj na jednom mjestu u posebnoj stručno-znanstvenoj instituciji u 2022.

*siljeg.mario@gmail.com
Water management in Republic of Croatia is financed from several different
sources, but EU funding is the most important. Through the Operational Program
Competitiveness and Cohesion 2014-2020. and the National Recovery and
Resilience Plan 2021-2026. it is planned to finance projects worth a total of 1,7
billion EUR while for the Multiannual Financial Framework 2021-2027. the
reconciliation is still in progress. EU funds have given new impetus to water
management, and since 2016 there has been an increase in the availability and
quality of water for human consumption, an increase in the number of inhabitants
with the possibility of connecting to public sewerage systems and an increase in
the degree of wastewater treatment. The number of points where the quality of
bathing water is excellent, both at sea and on land, has also increased. Despite
everything, as much as 60% of untreated wastewater is still discharged in the
Mediterranean with significant pressures from tourism. In order to unite surface
and groundwater monitoring activities, as well as other activities necessary for
good water management and for reporting to the European Commission on the
state of water in Croatia, the Josip Juraj Strossmayer Water Institute was
established in the year 2022 as a special professional-scientific institution.

Neupitna je važnost vode u životu čovjeka, biljaka i životinja. Od ukupne količine
vode tek je 1 % slatke vode pristupačno čovjeku za korištenje. Gospodarenje
vodama podrazumijeva slijedeće djelatnosti: zaštitu od štetnog djelovanja voda
(zaštita od poplava), zaštita voda od zagađenja i korištenje voda. Na globalnoj
razini poljoprivreda je najveći korisnik svježe slatke vode, s udjelom od 70 %, a na
europskoj razini je to 30 %. U Hrvatskoj je nakon Domovinskog rata (sustavi
navodnjavanja su bili devastirani ili otuđeni) navodnjavanih površina bilo za 10 000
ha manje u odnosu na stanje prije Domovinskog rata. Hrvatski stručnjaci, uz dva
međunarodna konzultanta, napisali su Nacionalni projekt navodnjavanja i
gospodarenja poljoprivrednim zemljištem i vodama u Republici Hrvatskoj
(NAPNAV), u kojem su dali stručne smjernice i okvire za osiguranje realizacije
održivog sustava navodnjavanja. Planirane površine navodnjavanja prema
NAPNAV-u su 65 000 ha (6,5 % obradivih površina). Realizacijom NAPNAV-a do
2022. godine omogućeno je navodnjavanje na 13 000 ha, a za 90-tak lokacija
izrađuju se studijske dokumentacije koje bi u narednom razdoblju omogućile
navodnjavanje na 124 000 ha.

The significance of water in the life of a human being, plants, and animals is
unquestionable. Out of the total water quantity, barely one percent of freshwater is
accessible to human consumption. Water management implies the following
activities: (1) protection from a harmful effect of water (flood protection), (2) water
protection, and (3) water consumption. On a global scale, agriculture is the largest
freshwater consumer, with a seventy percent share, being represented by thirty
percent at the European level. In Croatia, the irrigated areas subsequent to the
Homeland War amounted to ten thousand hectares less than with regard to those
in a situation prior to the Homeland War (as the irrigation systems were
devastated or misappropriated). The Croatian experts, with the assistance of two
international consultants, drafted the National Project of Irrigation and Land and
Water Management in the Republic of Croatia (NAPNAV), in which they provided
the guidelines and frameworks to assure the realization of a sustainable irrigation
system. Pursuant to the NAPNAV, the planned irrigation areas amount to sixty‐five
thousand hectares (i.e., to 6.5% of arable land). The realization of the NAPNAV up
to the year 2022 facilitated the irrigation of thirteen thousand hectares, and study
documentation is being drawn up for approximately ninety locations, which would
enable the irrigation of 124,000 ha in the forthcoming period.

The climate of Southeastern Europe, where Bosnia and Herzegovina and Croatia are
located, is changing in line with the global trends. The spatial and seasonal distribution of
precipitation is changing, while the temperatures increased 0.4-0.8 °C on average
compared to 1961-1990 average, most notably during summer (1.0-1.2 °C). Depending
on the different climate change scenarios, the temperatures in this area are projected to
further increase by 1.7-4.0 °C. In order to understand the effects of climate change on
regional water resources, it is important to assess the impacts of these changes on the
components of the water balance. The aim of this study was to determine and compare
the severity of changes in annual water balance between two climate periods (1961-1990
and 1991-2020). The results indicate that climate change has a different temporal and
spatial effect. All areas showed a positive trend in mean air temperature (0.29-0.36 °C
per decade), reference evapotranspiration (5.96-32.14 mm per decade) and soil moisture
deficit (2.75-31.63 mm per decade), while precipitation, total runoff, amount of snow and
actual evapotranspiration vary depending on the location and time period. The key
characteristic of the 1991-2020 period compared to 1961-1990 is the greater variation of
all components of the water balance.

Groundwater is the main source of drinking water in the Republic of Croatia where
over 90% of water supply is from groundwater reserves. Also, 50% of the state
territory are karst aquifers which are high quality groundwater reservoirs. Due to
their hydrogeological structure, they are very vulnerable to anthropogenic
influences. Therefore, they require protection measures defined based on the
results of detailed hydrogeological research, among which are methods for
groundwater vulnerability assessment. Such methods assume that the natural
chemical, biological and physical properties of an area may, to some extent,
contribute to the protection of groundwater from external impacts. The KAVA
method was applied in the Bokanjac - Poličnik catchment area and results will be
presented in this paper. KAVA is multiparameter method, uses four parameters:
cover deposits, infiltration impact, aquifer conditions and precipitation impact, and
can assess the intrinsic vulnerability of aquifers and/or springs. Result of the
assessment are maps made using GIS tools. In addition, a hazard map and risk
map for groundwater contamination under the influence of agricultural production
were prepared. The comprehensive analysis conducted in this way indicates the
parts of the basin that pose a threat to the groundwater quality of this area.

KVALITETA VODE ZA NAVODNJAVANJE I
KRITERIJI/STANDARDI U HRVATSKOJ - DOPRINOS

Kvaliteta vode koja se koristi za navodnjavanje, trebala bi zadovoljavati propisane
kriterije. Pokazatelji koji se najčešće utvrđuju su električna vodljivost (EC), ukupne
otopljene soli (TDS), rezidualni natrij karbonat (RSC) i omjer apsorpcije natrija
(SAR). Voda može sadržavati i štetne tvari bez obzira dali se navodnjavanje provodi
iz površinskih voda ili podzemne vode. Porijeklo onečišćenja mogu biti otpad,
netretirane otpadne vode ili intruzija slanih voda. Korištenje vode loše kvalitete,
može uzrokovati probleme u tlu kao što je alkalitet, salinitet, povećana koncentracija
natrija, toksičnost i sl. U Koprivničko-križevačkoj županiji (KKŽ) a i u cijeloj
Hrvatskoj, navodnjavanje je za sada slabo zastupljeno u poljoprivredi. Obzirom na
klimatske promjene i trendove jako suhih i vručih sezona, od sve većeg značaja je
provođenje navodnjavanja. Prema rezultatima utvrđivanja kvalitete podzemne vode

IRRIGATION WATER QUALITY AND CRITERIA/STANDARDS
IN CROATIA - CONTRIBUTION TO THE ENVIRONMENT
AND INDUSTRY

The water quality used for irrigation should meet the prescribed criteria. The most
commonly determined indicators are electrical conductivity (EC), total dissolved
salts (TDS), residual sodium carbonate (RSC) and sodium absorption ratio (SAR).
Water can also contain harmful substances, regardless of whether irrigation is
carried out from surface water or groundwater. The origin of the pollution can be
waste, untreated wastewater or saltwater intrusion. The use of poor water quality
can cause soil problems such as alkalinity, salinity, increased sodium concentration,
toxicity, etc. In Koprivnica-Križevci county (KKŽ) and throughout Croatia, irrigation
is currently poorly represented in agriculture. Given the climate change and the
trends of very dry and hot seasons, the implementation of irrigation is of increasing
importance. According to the results of determining the groundwater quality for
irrigation in KKŽ, the values of the indicators are satisfactory (EC = <0.7 dS/m; TDS
= <450 mg/l; RSC = <1.25 meq/l; SAR = <3.0 meq/l) for use in agriculture. However,
since there are no standards and criteria in Croatian regulations that would define
water quality, the results are compared with European/world standards. Water
quality testing and the adoption of standards/criteria in Croatia could contribute to
the future development of agriculture in increasingly unfavorable climatic conditions
and prevent environmental pollution. This would ensure more efficient cultivation of
plants, which also contributes to production in our own food industry.

U cilju organiziranja navodnjavanja, te okrupnjavanja poljoprivrednog zemljišta, izmjenu
strukture poljoprivredne proizvodnje, uvođenje dohodovnih kultura, osiguraju preduvjeti za
primjenu novih tehnologija u uvjetima navodnjavanja Vlada Republike Hrvatske 17.
studenog 2005. godine donijela je Nacionalni projekt navodnjavanja i gospodarenja
poljoprivrednim zemljištem i vodama (udaljnjem tekstu: NAPNAV), a čija provedba bi trebala
rezultirati boljim korištenjem prirodnim resursa za učinkovitiju poljoprivrednu proizvodnju.
Prema NAPNAV-u svaka županije izrađuje svoje planove navodnjavanja, te je u skladu s
navedenim Skupština Županije 11. ožujka 2006. godine donijela Plan navodnjavanja
područja Osječko-baranjske županije ("Županijski glasnik" broj 3/06.). Plan navodnjavanja
Županije predstavlja opsežan i sustavno izrađen planski dokument koji je osnova za daljnje
detaljnije rješavanje konkretnih projekata navodnjavanja na pojedinim lokacijama Županije.
NAPNAV na području naše Županije provodi se već dugi niz godina u suradnji s Hrvatskim
vodama i nadležnim ministarstvom. Tijekom provedbe NAPNAV-a na području Županije
izrađena je projektna dokumentacije za pojedine sustav navodnjavanja u kojima su utvrđeni
budući korisnici, ishođene su lokacijske, odnosno građevinske dozvole. Na području
Osječko-baranjske županije u tijeku je gradnja četiri sustava navodnjavanja, od kojih su tri
financirana u cijelosti iz Programa ruralnog razvoja Republike Hrvatske, a to su: Sustav
navodnjavanja mala šuma-Veliki vrt, Sustav navodnjavanja Poljoprivredni institut Osijek i
Sustav navodnjavanja Budimci-Krndija. Ukupan obuhvat navedenih sustava navodnjavanja
iznosi 854,50 ha Četvrti sustav navodnjavanja koji se gradi na području Županije je Sustav
navodnjavanja Puškaš obuhvata 925 ha, čije izgradnje je investitor Hrvatske vode, a
Županije je sufinancijer. Izgradnjom ovih sustava navodnjavanja, kao i drugih planiranih
sustava navodnjavanja stvorit će se uvjeti za stabilnu poljoprivrednu proizvodnju u sve
izraženijim uvijenima klimatskih promjena, kao i uvjeti za promjenu sjetvene strukture
površina i prelazak na radno intenzivne proizvodnje, odnosno razvoj povrtlarske i voćarske
proizvodnje. Ključne riječi: Nacionalni projekt navodnjavanja I gospodarenja poljoprivrednim

*silva.wendling@obz.hr
To organize irrigation and consolidation of agricultural land, change the structure of
agricultural production and the introduction of income crops, and provide prerequisites for
the application of new technologies in irrigation conditions, the Government of the Republic
of Croatia adopted the National Project for Irrigation and Management of Agricultural Land
and Water (hereinafter: NAPNAV) on 17 November 2005, the implementation of which
should result in better use of natural resources for more efficient agricultural production.
According to NAPNAV, each county prepares its irrigation plans, and per the above, the
County Assembly adopted the Irrigation Plan of the Osijek-Baranja County on March 11,
2006 ("County Gazette" No. 3/06). The County Irrigation Plan is a comprehensive and
systematically prepared planning document that is the basis for further detailed solutions to
specific irrigation projects at individual locations in the County. NAPNAV, in our County, has
been implemented for many years in cooperation with Croatian Waters and the competent
ministry. During the implementation of the NAPNAV in the County, project documentation
was prepared for individual irrigation systems in which future users were identified, and
location and construction permits were obtained. In the area of Osijek-Baranja County, four
irrigation systems are being built, three of which are fully financed by the Rural Development
Program of the Republic of Croatia, namely: Small Forest Irrigation System-Large Garden,
Irrigation System Agricultural Institute Osijek and Irrigation System Budimci- Krndija. The
total coverage of these irrigation systems is 854.50 ha. The fourth irrigation system being
built in the County is the Puškaš Irrigation System, which covers 925 ha, the investor being
Hrvatske vode, and the County is a co-financier. The construction of these irrigation systems
and other planned irrigation systems will create conditions for stable agricultural production
in the increasingly pronounced twists of climate change, as well as conditions for changing
the sowing structure and transition to labor-intensive production and development of
vegetable and fruit production.

U ovom radu ispitana je učinkovitost pročišćavanja otpadnih voda iz separatora ulja
hibridnim postupkom, odnosno kombinacijom elektrokemijskih (EK) i naprednih
oksidacijskih procesa (NOP). Obje metode postale su predmet brojnih istraživanja jer
pročišćavaju otpadnu vodu koristeći električnu struju umjesto kemijskih reagensa i
mikroorganizama koji mogu biti ekonomski i operativno nepovoljniji. Prema dosadašnjim
istraživanjima, elektrokoagulacija je pokazala visoku učinkovitost pročišćavanja uz niske
troškove izgradnje, pogona i održavanja. NOP imaju široku primjenu u obradi otpadnih
voda, a njihova svrha je oksidacija organske tvari do završih produkata CO2 i H2O. U radu
je ispitana učinkovitost pročišćavanja u ovisnosti o materijalu elektroda, jakosti struje,
otopljenom kisiku, električnoj vodljivosti, pH-vrijednosti, temperaturi, KPK vrijednoste te
koncentraciji ukupnih ugljikovodika ili mineralnih ulja. Također je ispitana mogućnost
primjene nastalog otpadnog mulja kao djelomične zamijene gline u proizvodnji opeka.
Proizvedene su četiri serije opeka s ugrađenom pročišćenom vodom i djelomičnom
zamjenom dijela gline muljem generiranog hibridnim postupkom pročišćavanja.
Proizvedenim opekama određena su geometrijska svojstva, ravnost, obujam i postupak
šupljina, tlačna čvrstoća, otpornost na zamrzavanje i odmrzavanje, vodoupojnost,
početno upijanje vode te fizikalno-kemijska i mehanička svojstva. Zadovoljavajuća
učinkovitost uklanjanja KPK i mineralnih ulja iz otpadne vode ukazuje na opravdanu
primjenu ovog procesa u pročišćavanju otpadnih voda.

In this study, wastewater from oil separators was treated by the ombination of
electrochemical (EC) and advanced oxidation processes (AOP) since those
methods can have economical and operational benefits due to a high treatment
performance with low construction, operation, and maintenance costs. In this study,
the efficiency of wastewater treatment by a combination of EC and AOP was
investigated due to electrode materials, current, dissolved oxygen, electrical
conductivity, pH, water temperature, chemical oxygen demand (COD) and total
hydrocarbons or mineral oils. The possibility of sludge usage as a partial substitute
for clay in brick production has been also investigated by the production of four
series of bricks with embedded purified water and partial replacement of part of the
clay with sludge. The manufactured bricks were determined on the basis of
geometric properties, flatness, volume and course of voids, compressive strength,
resistance to freezing and thawing, water absorption, initial water absorption, and
physicochemical and mechanical properties such as soluble salt content, etc.
Satisfactory efficiency was obtained in the removal of COD and mineral oils from oil
separator effluents, proving and justifying the application of this process for the
treatment of this type of effluents.

Problemi vezani uz kvalitetu električne energije prisutni su u većini industrija. Za
kvalitetu električne energije na mjestu priključka odgovorni su operator sustava i
korisnik mreže. Obzirom da pogon za proizvodnju vode za ljudsku potrošnju mora
trajno raditi, nužna je pouzdana i trajna opskrba električnom energijom
zadovoljavajuće kvalitete sukladno HRN EN 50160:2012. Također,
elektromagnetski povratni utjecaj trošila korisnika na elektroenergetsku mrežu mora
biti unutar dozvoljenih vrijednosti propisanih Mrežnim pravilima distribucijskog
sustava (NN 74/18, 52/20). Niskonaponska elektroenergetska mreža pogona
proizvodnje vode Nebo Pustara sadrži osjetljiva elektroenergetska i elektronička
trošila, stoga navedena oprema zahtjeva električnu energiju zadovoljavajuće
kvalitete. Također, navedena trošila imaju nelinearnu strujno – naponsku
karakteristiku pa su i sami izvor štetnosti lošeg utjecaja na kvalitetu električne
energije. U svrhu spriječavanja neželjenih događaja s negativnim utjecajem na rad
pogona proizvodnje vode, uzrokovanih lošom kvalitetom električne energije te
svođenje nedopuštenog povratnog utjecaja nelinearnih trošila na elektroenergetsku

Power quality issues are pervasive throughout most industries. The system operator
and the network user are responsible for the power quality at the point of common
coupling (PCC). Since the water treatment plant must operate permanently, a
reliable and permanent power supply of satisfactory quality is necessary in
accordance with HRN EN 50160:2012. Also, the electromagnetic feedback of the
load consumption on the power grid must be within the permitted values prescribed
by the Grid Code of the distribution system (NN 74/18, 52/20). Low-voltage power
grid of the water treatment plant Nebo Pustara contains sensitive electric and
electronic loads, therefore these loads requires power supply of satisfactory quality.
Also, these loads have non-linear voltage/current characteristic and they are a
source of power quality negative effects. In order to prevent adverse events with a
negative impact on the operation of water treatment plant, caused by poor power
quality, and reduce the impermissible impact of non - linear loads on the power grid,
a power quality analyzer PCube3 was installed at Nebo Pustara power sub -
substation. In accordance with the power quality analysis, the actions taken in the
user and distribution power grid are described in order to increase the production
reliability and stability of water treatment plant and water supply, reducing the
negative impact on plant operation and equipment and reducing the impermissible
feedback of non – linear loads.

U Hrvatskoj je i dalje značajan broj korisnika lokalnih vodovoda. Karakteristika voda
lokalnih vodovoda uobičajeno je zdravstvena neispravnost. Kao najčešći razlog
neispravnosti vode navodi se mikrobiološko onečišćenje te povišene koncentracije
teških metala. Najčešći postupak kojim se provodi dezinfekcija vode u pripremi vode
za piće je dezinfekcija spojevima na bazi klora. Međutim, time kao nusprodukti
reakcije klora i organske tvari, nastaju klorirani ugljikovodici i nitrozamini, a koji
mogu biti izrazito kancerogeni. Akumulacija ovih nusprodukata, zajedno s
akumulacijom teških metala u organizmu, povećavaju rizik od negativnih učinaka na
zdravlje. Alternativna metoda kondicioniranja voda, je elektrokoagulacija.
Elektrokoagulacijom se pomoću električnog polja i žrtvujućih elektroda stvaraju
koagulanti u cilju izdvajanja, agregiranja i taloženja onečišćenja iz vode. Ova se
metoda pokazala uspješnom za uklanjanje teških metala iz voda, ali i kao postupak
dezinfekcije. Cilj ovog rada je primjena elektrokoagulacije za uklanjanje arsena i
kroma te dezinfekciju sirove vode opterećene Escherichiom coli. Ispitivanja su
provedena u šaržnom reaktoru, uz 2 elektrode (1 anoda i 1 katoda) pri naponu od
62 V. Ispitana je učinkovitost procesa ovisno o materijalu elektrode (Fe, Al, Cu i
grafit) i vremenu trajanja tretmana. Osim grafitnih, sve elektrode su pokazale 100 %
učinkovitost uklanjanja As i Cr, dok se učinkovitost dezinfekcije razlikovala.

In Croatia, a significant percentage of people use local water supply systems. These
systems suffer from poor water quality. The most common contaminations are
microbiological contamination and elevated concentrations of heavy metals. The
most common procedure for disinfecting water is disinfection with chlorine-based
compounds. As a by-product of chlorine and organic matter carcinogenic
chlorinated hydrocarbons and nitrosamines are formed. The accumulation of these
by-products, together with the accumulation of heavy metals in organisms,
increases the risk of adverse effects on health. Electrocoagulation is an alternative
method of raw water conditioning. Electrocoagulation creates coagulants using an
electric field and sacrificial electrodes to separate, aggregate and precipitate
contaminants. This method has proven successful for removing heavy metals, but
also as a disinfection method. In this study electrocoagulation was used for the
removal of arsenic and chromium and disinfection of raw water enriched with
Escherichia coli. The process took place in a batch reactor, with 2 electrodes
(1 anode and 1 cathode) at 62 V. The efficiency depended on the electrode material
(Fe, Al, Cu and graphite) and the duration of the treatment. Except for graphite, all
electrodes showed 100 % efficiency for As and Cr removal, while disinfection
efficiency differed.

THE REMOVAL OF NEONICOTINOID INSECTICIDES IN A
FLATE-PLATE PHOTOREACTOR

The excessive and systematic use of neonicotinoids over several years has led to the
destruction of beneficial insect populations and ultimately threatens the foundations of
the food chain. Due to the environmental risks posed by their use, there is a need to
develop techniques and methods to prevent the bioaccumulation of insecticides and
other undesirable persistent compounds in the environment, to allow their complete
degradation, and create favorable conditions for environmental remediation. In the last
decade, heterogeneous photocatalysis, also known as "green" technology or energy-
saving technology, has been increasingly studied due to its environmental compatibility
and sustainability. The aim of this study was to investigate the photolytic and
photocatalytic degradation of neonicotinoids in an aqueous solution. Acetamiprid and
thiacloprid, two widely used insecticides, were used as model components.
Experiments were performed in a flat-plate photoreactor under conditions of
recirculation of the reaction mixture over an immobilized photocatalyst layer (TiO2
modified by urea) using two artificial lamps for simulation of solar irradiation (2.4% UVB
and 12% UVA; 300-700 nm). The catalyst used was characterized by XRD, UV/Vis-
DRS, BET, and SEM /EDX analysis. For most measurements, the reaction mixture was
sonicated for 15 minutes immediately prior to charging the reactor. The study focused
on the influence of the pH of the initial solution on the efficiency of photocatalytic and
photolytic degradation. It was found that photocatalytic degradation of the two model
components was most effective under acidic operating conditions, i.e., at pH 4.5, while
photolysis resulted in their minimum degradation. It was also observed that
pretreatment of the reaction mixture with ultrasound promoted photocatalytic
degradation, while in the case of photolytic degradation, the application of ultrasound
did not contribute to better degradation.

During the history of water management systems (both those that prevented floods
and those that provided irrigation or water supply) enabled the development of urban
civilizations and were the basis for the arrangement of significant spatial units. Their
history shows how much they have transformed the space in which people live, ie
how much their influence has enabled human existence. In this sense, a number of
examples with their importance as examples of tangible cultural heritage are equally
important as examples for directing today's spatial planning, not only in the direction
of protecting these historical values, but also ensuring sustainable development in
using their examples. Croatian and worldwide examples of historical water supply
systems and the history of water management are a significant element of the
spatial context and the basis for spatial planning. This work will present examples
from Croatia and the world that have changed their spatial and social environment
and that still provide a significant example of possible and necessary actions, but
also the dangers associated with water management and water resources in the
context of space planning.

AMENDMENTS TO ORDINANCE ON NATURAL MINERAL,
NATURAL SPRING AND TABLE WATERS
Željka Bauer Mikić*
Ministry of Agriculture, Ulica grada Vukovara 78, 10000 Zagreb, Hrvatska
*zeljka.bauer-mikic@mps.hr
The primary purpose of the EU natural mineral water legislation is to protect the
health of consumers, to prevent consumers from being misled, to ensure fair-trading
and to facilitate the functioning of the internal market. The Ordinance on natural
mineral, natural spring and table waters (Official Gazette 85/19) prescribes the
requirements that natural mineral, natural spring and table waters must meet when
using, treating and placing on the market. Amendments to the said Ordinance
change the name "natural spring water" to "spring water" in order to further
harmonize with Directive 2009/54/EC on the exploitation and marketing of natural
mineral waters. Requirements that natural mineral water must meet regarding the
presence of total and individual pesticides are prescribed. Changes in the procedure
for the recognition of natural mineral and spring waters are prescribed in connection
with the necessary documentation, and the possibility of conducting a site-visit
during the implementation of the recognition procedure is introduced. Sampling of
natural mineral and spring waters for conducting laboratory analyses for the
purposes of the recognition procedure is prescribed in more detail. An exact list of
statements that can be used in the labelling of natural mineral waters is prescribed.
The method of assessing the conformity of the results of analyses with the values
of the corresponding prescribed parameters is also prescribed. In order to enable
producers of natural spring waters to adapt the provisions a transitional period of 3
years is prescribed, from the date of entry into force of the Ordinance, and in the
case of gallons for water appliances 5 years and within which they are obliged to
reconcile declarations.

Hydro energy is one of the least toxic and most powerful and under-utilized
renewable energy sources in the world. New hydrokinetic turbine technologies are
being developed for open flow environments as this is much less disruptive to the
local ecosystem than traditional damming as the structure does not occupy the
entire river and allows free flow in and around the structure. With regards to the
calculations and testing, it has been shown that the Davidson-Hill Venturi Turbine
Technology (DHV) is potentially the most efficient hydrokinetic turbine in the world.
The idea of the turbine operational work is based on the Venturi effect in the open
watercourses. The intention of the research is to present innovation and test
turbines on real sites in Europe, especially in Croatia. Such will consist of the sizing
of the turbines, building the prototype, comparison of the calculated and measured
values, as well as the proposals for the improvements. A special accent will be on
providing the foundation and an assembly with regard to the base of the river bed,
bridges, or similar constructions. It should be mentioned that DHV turbines could be
used to harness tidal flow in the open ocean on a mass scale.

Upravljanje vodama bazirano je na hidrološkim podatcima, među kojima su podatci
o oborinama često i najvažniji. Oborina je neizostavan dio tumačenja kruženja vode
u prirodi i suvremeno se redovito opaža u okviru praćenja vremenskih prilika. U radu
se prvo opisuju osnove postupaka prikupljanja podataka o oborinama, odnosno
korištenja raznih kišomjera. Zatim se ukazuje na neka iskustva problematične
interpretacije raspoloživih podataka. Primjerima se ukazuje na vremensku i
prostornu varijabilnost oborinskih događaja te se istiću neki načini prikaza obrađenih
skupova podataka. Na kraju se predstavlja i primjer složenije analize hidroloških
podataka kojom se omogućuje uočavanje elementa klimatskih promjena.

Water management is based on hydrological data, among which rainfall data are
often the most important. Rainfall is an indispensable part of the interpretation of
water circulation in nature and is nowadays regularly observed in the context of
monitoring weather conditions. The paper first describes the basics of the procedure
for collecting data on rainfall, i.e. the use of various rain gauges. Then, some
experiences of problematic interpretation of available data are pointed out.
Examples indicate the temporal and spatial variability of rainfall events. Some ways
of displaying processed data sets are highlighted. Finally, an example of a more
complex analysis of hydrological data is presented, which enables the observation
of the element of climate change.

Karakteristike podzemne vode uvjetovane su različitim hidrogeološkim parametrima
kao što su poroznost, specifični prinos (koeficijent skladištenja ili efektivna
poroznost) i hidraulička vodljivost te interakcijom različitih društvenih aktivnosti i
fizičkog okoliša. Podzemna voda je najkvalitetniji vodni resurs za potrebe korištenja
voda. Potrebno je održavati hidrodinamičku ravnotežu između prirodnog i/ili
umjetnog prihranjivanja i zahvata podzemnih voda. Dok je većina strategija
upravljanja podzemnim vodama usmjerena na povećanje ponude, upravljanje
potražnjom također je ključno za sprječavanje sniženja razine podzemnih voda i
osiguravanje dostupnosti podzemne vode tijekom suše. Stalno snižavanje razine
podzemne vode ukazuje na nerazumno iscrpljivanje i smanjenje akumulacije
podzemnih voda. Snižavanjem razine podzemnih voda dolazi i do snižavanja tla.
Na količinu i kakvoću podzemnih voda nekog područja utječu klimatski uvjeti, brzina
obnavljanja, količina crpljenja, urbanizacija, poljoprivreda, namjena zemljišta i
vegetacija. S obzirom na navedeno od iznimne je važnosti osigurati dovoljne
količine i kakvoću podzemnih voda što se može ostvariti održivim upravljanjem.
Održivo upravljanje podzemnim vodama podrazumijeva upravljanje usmjereno na
osiguranje dovoljnih količina podzemnih voda dobrog stanja te višestruke
dugoročne koristi bez pogoršanja uvjeta koji uzrokuju značajne ekonomske,
društvene ili ekološke utjecaje. Potrebno je osigurati program praćenja stanja
podzemnih voda i u skladu sa stanjem podzemnih voda primijeniti adekvatno
upravljanje. Održivo upravljanje podzemnim vodama u uvjetima klimatskih
promjena postalo je važan element globalne politike.

Groundwater properties are determined by various hydrogeological parameters
such as porosity, specific yield (storage coefficient or effective porosity), and
hydraulic conductivity, as well as by the interaction of various social activities and
the physical environment. Groundwater is the highest-quality water resource for
water use. It is necessary to maintain a hydrodynamic balance between natural
and/or artificial recharge and groundwater extraction. While most groundwater
management strategies aim to increase supply, demand management is also
instrumental in preventing groundwater degradation and ensuring groundwater
availability during periods of drought. A continuous decline in groundwater levels
indicate an inadequate pumping and a reduction in groundwater storage. A
reduction in groundwater levels also leads to soil erosion. The quantity and quality
of groundwater in a given area is affected by climatic conditions, the renewal rate,
the amount of pumping, urbanization, agriculture, land use, and vegetation. In light
of the above, it is of utmost importance to ensure sufficient quantity and quality of
groundwater, which can be achieved through sustainable management. Sustainable
groundwater management is a management that seeks to ensure sufficient
quantities of groundwater in good condition and with multiple long-term benefits
without deteriorating the conditions that result in significant economic, social, or
environmental impacts. A groundwater status monitoring program should be
established and appropriate management should be implemented according to
groundwater status. Sustainable groundwater management under climate change
conditions has become an important element of global policy.

Interesantne i neočekivane zakonitosti tečenja podzemne vode predstavljaju
zagonetku inženjerima prilikom projektiranja hidrotehničkih objekata. Tečenje
podzemne vode kroz tlo ispod objekta (betonske brane) ili kroz tijelo objekta (nasipi
i nasute brane) naziva se procjeđivanje ili filtracija. Kako bi se upoznali s
fenomenom procjeđivanja napravljen je fizikalni model gravitacijske brane sa ciljem
vizualizacije procjeđivanja kroz tlo ispod brane. Model je napravljen u laboratoriju
Građevinskog i arhitektonskog fakulteta u Osijeku. Simulirano je stacionarno
procjeđivanje ispod brane za nekoliko različitih struktura temeljnog tla. Karakter
procjeđivanja procijenjen je preko Darcyjeve jednažbe i konstruirane strujne mreže
uz pomoć fluorescente otopine. Uspoređena je količina procjeđivanja kroz tlo
različite strukture te je pokazan utjecaj hidrauličkog gradijenta na pojavu likvefakcije
i unutarnje erozije. Analizirana je raspodjela pornih tlakova i vrijednost sile uzgona
ispod temelja. Konačno, pretpostavljene su i vrednovane mjere koje inženjeri koriste
prilikom suočavanja s procjeđivanjem, kako bi se utjecalo na hidraulički gradijent i
spriječilo lokalnu eroziju.

Interesting and unexpected rules of groundwater flow represent a mystery to
engineers when designing hydraulic structures. The flow of groundwater through
the soil below a building (such as gravity dams) or through the body of a building
(embankments and backfill dams) is called seepage. In order to get acquainted with
the phenomenon of seepage, a physical model of the gravitational dam was made
with the aim of visualizing the seepage through the soil below the dam. The model
was built in the laboratory of Faculty of Civil Engineering and Architecture in Osijek.
Stationary seepage below the dam was simulated for several different types of
foundation soil. The seepage characteristics was estimated using the Darcy's law
and a constructed flow grid using a fluorescent solution. The seepage through the
different types soil was quantified and compared. The influence of the hydraulic
gradient on the occurrence of liquefaction and internal erosion was shown. The
distribution of pore pressures and the value of buoyancy force below the foundation
were analyzed. Finally, measures used by engineers to prevent local erosion are
assumed and evaluated.

Prirodne katastrofe i katastrofe uzrokovane čovjekovom djelatnošću predstavljaju
sve veću prijetnju u vodoopskrbi stanovništva pitkom vodom. Opasnosti poput suša,
poplava, slučajnih onečišćenja i potresa najveći su rizici sigurne vodoopskrbe, za
čiju je obranu potrebno definirati usklađene mehanizme i protokole nadležnih
institucija. Iz tog razloga su u izmjenama i dopunama Zakona o vodi za ljudsku
potrošnju iz 2017. godine (NN 104/17) planovi sigurnosti voda definirani kao bitan
element upravljanja opasnostima i mogućim rizicima te su prema europskoj Direktivi
o vodi ispravan alat za sigurnu vodoopskrbu pitkom vodom. Glavni ciljevi projekta
MUHA, sufinanciranog iz programa INTERREG ADRION su izrada
harmoniziranoga plana, metoda i definiranih naredbi provedbe, kao odgovarajućih
mehanizama u slučaju opasnosti s ciljem poboljšanja planova sigurnosti voda.
Upravo će tako, jedan od glavnih alata projekta MUHA WASSP-DSS pomoći u
identificiranju i procjeni rizika mogućih opasnih događaja koji utječu na
vodoopskrbni sustav. Unaprjeđenje alata biti će moguće kroz konstituirajuću mrežu
UNAS, koja korisnicima pruža jednostavnu, učinkovitu i sigurnu transnacionalnu
platformu za razmjenu znanja i iskustava o MUHA alatu i daje smjernice za izradu
poboljšanih planova sigurnosti voda. Navedeni rezultati pomoći će u izradi
dokumenta strateškog usmjeravanja za uspješniju provedbu planova sigurnosti
voda. Uz navedene projektne rezultate, Hrvatski geološki institut provodi

Natural and man-induced disasters pose an increasing threat to the population's
drinking water supplies. Hazards such as droughts, floods, accidental pollutions and
earthquakes are the most significant risks for securing water supplies, for which is
necessary to define harmonized mechanisms and protocols of responsible
institutions. For this reason, the amendments to the Water Act for Human
Consumption of 2017 (OG 104/17) define water safety plans as an important
element in managing hazards and possible risks in the water supply systems, as
well as EU Water Directive 2020/2184 which individuates water safety plans as the
correct tool for water utilities to ensure safe, drinkable water. The main objectives of
the MUHA project, co-financed by the INTERREG ADRION, are aimed to develop
harmonized plans, methods and defined implementation orders as appropriate
mechanisms in case of hazards and to improve water safety plans. One of the
MUHA project's main tools WASSP-DSS will help identify and assess the risk of
possible hazardous events impacting the water supply systems. The tool will be
improved by the constituting UNAS network, which provides users an easy, effective
and safe transnational platform for sharing knowledge and experiences on the
MUHA tool and development of improved water safety plans. These results will lead
to developing a document with strategic guidance for more successful
implementation of water safety plans. In addition to the mentioned project results,
the Croatian Geological Survey is conducting hydrogeological research in the Zadar
hinterland, in the Bokanjac – Poličnik system, with an emphasis on the Golubinka
coastal karst spring.

Kopački rit je jedna od najvećih fluvijalno-močvarnih nizina u Europi, omeđena
Dravom i Dunavom u vrhu Baranjskog trokuta. Dinamika plavljenja održava veliku
raznolikost biljnog i životinjskog svijeta što predstavlja iznimnu prirodnu vrijednost
Kopačkog rita. Opstanku Kopačkog rita, između ostalog, prijeti opadanje razine i
onečišćenje podzemnih voda. Intenzivna poljoprivreda uzrokuje onečišćenje tla,
osobito umjetnim gnojivima i pesticidima koji se zatim ispiru i dospijevaju u
površinske i podzemne vode. U sklopu projekta Naturavita : monitoring stanja voda,
podzemnih voda, recentne sedimentacije, staništa i faune, provodi se hidrokemijski
monitoring u pet piezometarskih bušotina s ciljem određivanja kakvoće i porijekla
podzemne vode, utjecaja površinskih na podzemne vode, miješanja različitih voda
i vremena zadržavanja vode u podzemlju. Sukladno projektnom zadatku, Nastavni
zavod za javno zdravstvo Osječko-baranjske županije provodi uzorkovanje i
ispitivanje podzemnih voda na osnovne fizikalno-kemijske i kemijske pokazatelje
(električna vodljivost, otopljeni kisik, pH vrijednost, osnovni anioni i kationi) te
onečišćujuće tvari (nitrati, pesticidi i specifične onečišćujuće tvari). Ispitivanje se
provodi tijekom dvije godine, jednom mjesečno na svih pet piezometara.

Kopački Rit is one of the largest fluvial lowlands in Europe, bordered by the river
Drava and the Danube in the Baranja triangle. The flood dynamics maintains a high
biological diversity, which is an exceptional natural value of Kopački Rit. The
sustainability of Kopački Rit, among other things, is threatened by groundwater
decline and pollution. Intensive agriculture causes soil pollution, especially by the
runoff and leaching of fertilizers and pesticides which are reaching and
contaminating surface water and groundwater. As a part of the “Naturavita project:
monitoring of surface water, groundwater, recent sedimentation, habitats and
fauna”, hydrochemical monitoring is carried out in five piezometer wells in order to
determine the quality and origin of groundwater, surface water impact on
groundwater, mixing different waters and underground water retention capacity. In
accordance with the aims of the Naturavita project, the Institute of Public Health for
the Osijek – Baranja County conducts groundwater sampling and testing for basic

Surfactants are organic molecules which reduce the surface tension. They have a
amphiphilic structure with polar head with hydrophilic group that has affinity to water;
and a nonpolar tail – a “fatty“ hydrophobic alkyl chain with 8 to 22 carbon atoms. There
are four main groups of surfactants - anionic, cationic, amphoteric and nonionic. Anionic
surfactants are usually used as washing agents in households and industry, while
cationic surfactants are used as disinfectant, preservatives and cleaning agents. Except
their positive sides, surfactant have a negative effect on the cells (they disintegrate the
cell membrane), they can cause skin irritation and prevent the oxygen exchange on the
air/ware phase borders endangering the aquatic life. Since surfactants are widely used,
there is a need to establish reliable protocols for their quantification in commercial
products (as a quality control tool) and in waters (and wastewaters). Classical methods
for their detection, like two-phase titration, are not reliable, require a trained personnel
and use toxic solvents. To overcome this issues, surfactants sensors are used. They
are fast in response, reproducible, do not use toxic solvents and are easy to use. A new,
low-cost, simple and fast potentiometric surfactant sensor based on the 2-methyl-1,3-
dioctadecyl-1H-benzo[d]imidazol-3-ium - tetraphenylborate ionophore was fabricated,
characterized and tested on model and real samples of commercial products and
wastewaters containing surfactants. The proposed sensor was suitable for surfactant
quantification at high and low concentrations. The results showed good agreement with
the standard method.

Voda iz dva hidroakumulaciona jezera izgrađenih na rijeci Neretvi, Jablanica i
Salakovac je bila temom ispitivanja. Vremenom su ove hidroakumulacije postale od
iznimne važnosti za ljude, na njima su izgrađena i brojna ribogojilišta u kojima se
između ostalih uzgaja i kalifornijska pastrmka. Riba uzgojena u ovim jezerima može
akumulirati toksične metale u visokim koncentracijama, koji u konačnici
predstavljaju ozbiljan rizik. Živa (Hg), kadmijum (Cd) i olovo (Pb) privlače veliku
pažnju jer su skloni akumuliranju u tkivima ribe i mogu naštetiti ljudskom zdravlju
ako se unose hranom. Ova studija je imala za cilj da ispita fizičko hemijske osobine
i zagađenje vode teškim metalima (Cu, Zn, Hg, Cd i Pb) u dva hidroakumulaciona
jezera (Jablanica i Salakovac) na rijeci Neretvi. Uzorci vode prikupljeni su na
šesnaest lokacija iz ova dva jezera u rano proljeće i ljeto. Fizičko-hemijski parametri
koji su ispitani i analizirani su: okus, miris (bez), boja (bez), ukupna tvrdoća
(180 i 300 mg/L CaCO3), mutnoća (2,1-5,31 NTU), pH vrijednost (7,2-7,5), utrošak
KMnO4 (1,48 do 4,39 mg/L O2), amonijak (1,76 - 2,83 mg/L NH4+), nitrati
(1,97 - 2,58 mg/l NO3-), nitriti (0,002 - 0,009 mg/L NO2-). Ispitivan je nivo teških
metala: olovo (0,63 - 2,52 µg/L), živa (0,01 µg/L), kadmij (0,93 - 0,97 µg /L), bakar
(4,30 - 6,70 µg/L) i cink (1,40 - 1,80 µg/L).

Water from two hydro-accumulation lakes built on the Neretva River, Jablanica and
Salakovac was the subject of research. Over time, these reservoirs have become
extremely important for humans, and numerous fish farms have been built on them,
where, among others, California trout are farmed. Fish grown in these lakes can
accumulate toxic metals in high concentrations, which ultimately pose a serious risk.
Mercury (Hg), cadmium (Cd) and lead (Pb) attract a lot of attention because they tend
to accumulate in fish tissues and can harm human health if ingested. This study aimed
to examine the physicochemical properties and pollution of water with heavy metals
(Cu, Zn, Hg, Cd and Pb) in two hydro-accumulation lakes (Jablanica and Salakovac)
on the Neretva River, which we did through two samplings during the quarterly water
analysis. Water samples were collected at sixteen locations from lakes Jablanica and
Salakovac in the early spring and summer of 2018. Physico-chemical parameters
tested and analyzed were: taste, odor (no), color (no), total hardness (180 and 300 mg
/ L CaCO3), turbidity (2.1 - 5.31 NTU), pH value 7.2 - 7.5), consumption of KMnO4
(1,48 - 4,39 mg/L O2), ammonia (1.76 - 2.83 mg / L NH4+), nitrates (1.97 - 2.58 mg) / l
NO3-), nitrites (0.002 - 0.009 mg / L NO2-). The level of heavy metals was examined:
lead (0.63 - 2.52 µg / L), mercury (0.01 µg / L), cadmium (0.93 - 0, 97 μg / L), copper
(4.30 - 6.70 μg / L) and zinc (1.40 - 1.80 μg / L).

Hrvatska je jedna od rijetkih zemalja koja ima značajne rezerve čiste pitke vode. Na
5. je mjestu u Europi te 42. u svijetu. 68,9 % slatke vode zarobljeno je u ledenjacima,
0,3 % je u jezerima i rijekama, a 30,8 % u podzemnim vodama. Hrvatska ima
dovoljne zalihe vode za svoje potrebe za nekoliko sljedećih desetljeća, a značajno
vodno bogatstvo predstavljaju podzemne vode (12%) koja se u oko 85 % koristi za
vodoopskrbu. Podzemne vode, nalaze se unutar šupljina i pora u tlu te u stijenama.
Nastaju infiltracijom ili gravitacijskim procjeđivanjem s površine u procesu kruženja
vode u prirodi koji je stalan proces i koji omogućuje život na planeti: voda iz mora i
oceana isparava, u atmosferi se kondenzira i u različitim oblicima pada na tlo.
Površinskim ili podzemnim tokovima opet dospijeva do mora i oceana te se proces
neprestano ponavlja. Izotopi su oblici kemijskog elementa koji imaju isti broj protona,
ali različit broj neutrona u jezgri i stoga različite atomske mase. Budući se voda
sastoji od atoma kisika i vodika upravo analizom omjera njihovih izotopa mogu se
saznati vrlo korisne informacije o tokovima podzemnih voda, geografskom porijeklu
flaširanih voda, identifikaciji izvora vode, praćenju hrane ka svom mjestu
proizvodnje i otkrivanje krivotvorenja (patvorina), identificiranje uvjeta rasta biljnih
sustava, istraživanje povijesti klimatskih događaja i analiza ledenih jezgri te
razumijevanje protoka vode podrijetlom iz oceana.

Croatia is one of the few countries that has significant reserves of clean drinking
water and is on 5th place in Europe and 42nd in the world. 68.9% of fresh water is
trapped in glaciers, 0.3% in lakes and rivers, and 30.8% in groundwater. Croatia has
sufficient water supplies for its needs for the next few decades, and a significant
water wealth is groundwater (12%), which in about 85% is used for water supply.
Groundwater is found inside cavities and pores in the soil and in rocks. They are
formed by infiltration or gravitational leachate from the surface in the process of
circulating water in nature which is a constant process and which enables life on the
planet: water from the sea and ocean evaporates, condenses in the atmosphere
and falls to the ground in various forms. Surface or underground currents reach the
sea and oceans again, and the process is constantly repeated. Isotopes are forms
of a chemical element that have the same number of protons, but different numbers
of neutrons in the nucleus and therefore different atomic weights. Since water
consists of oxygen and hydrogen atoms, the analysis of their isotopes ratios can
provide very useful information on groundwater flows, geographical origin of bottled
water, identification of water sources, monitoring food to its place of production and
detection of counterfeits, identifying plant growth conditions, research into the
history of climate events and analysis of ice cores, and understanding the flow of
water originating from the ocean.
Keywords: groundwater, isotopic composition, geographical origin, climate events

Microplastics (MPs), commonly defined as particles less than 5 mm, are a persistent
ubiquitous anthropogenic contaminant that can be found in every environment,
making it a global environmental, health and socioeconomic problem. Due to their
high surface area, MPs adsorb toxic pollutants that become bioavailable to
organisms upon ingestion as they are often mistaken for food leading to
biomagnification. The sampling area represents the lower part of the Krka River
Estuary and is under direct anthropogenic influence from city of Šibenik runoff
waters, nautical and communal ports, city harbor, tourism, mariculture, and fishing.
Estuaries and harbors have been recognized as hotspots and transfer pathways for
MPs primarily because of the vicinity of urban environment that emits contaminants
from various sources. The main focus of this research was to determine MPs size,
shape, color, surface area and abundance in surface water using volume-reduced
samples collected by Manta trawls. Laboratory protocol included sieving, wet
peroxidation (H2O2), density separation (saturated NaCl solution), sonication and
filtration. Filter papers were then visually inspected for MPs and stained with Nile
Red (NR) fluorescent dye. Image processing and measurements were carried out
with ImageJ open-source software.

Due to climate change and the global trends of sea level rise, seawater intrusion into
coastal aquifers is leading to an increasing risk of soil and water salinization in coastal
river deltas. Although the problem of seawater intrusion and salinization of surface and
groundwater occurs in all of the Croatian coastal areas, these processes are most evident
in the intensively hydromeliorated and cultivated areas of Neretva River delta which is
considered one of the most vulnerable areas to climate change in Croatia. In such
environments, monitoring systems are necessary for quality and timely decision making.
With the project DELTASAL, an automatic advanced water monitoring system was
established at two locations in the Neretva River delta. Automatic multiparameter probes
for monitoring physicochemical parameters such as water temperature, water depth, pH,
oxidation-reduction potential, electrical conductivity, salinity, total dissolved solids,
seawater specific gravity, resistivity and dissolved oxygen were installed in drainage
canals for surface and shallow piezometers for groundwater monitoring. The
multiparameter probes are connected to a GPRS modem that collects and transmits data
at hourly resolution. The collected data are automatically sent and stored in a newly
developed database. The data were compared and validated with laboratory data from
long-term monitoring of water salinity at the same locations. This paper presents the
results of a one-year period (March 2021 to March 2022) of surface and groundwater
quality monitoring under the established advanced monitoring system.

Bosnia and Herzegovina have very specific geomorphological and hydrological
features, which result in numerous and diverse karst spring habitats. These habitats
are characterized by physico-chemical stability, low water temperatures with small
annual fluctuations, high oxygen and carbon dioxide concentrations, and generally
oligotrophic conditions, which makes them extremely valuable ecosystems in terms
of biodiversity. From an economic and hydrological point of view, springs are
generally perceived as sources of clean drinking water, resulting in most springs
being captured for water supply, and the effects of environmental changes caused
by human activity are visible in many Dinaric karst springs. Due to their isolation and
fragmentation and obvious anthropogenic impact, spring habitats are considered
particularly vulnerable to climate change. According to forecasts, these ecosystems
will be exposed to multiple pressures caused by changes in water regime, rising
water temperatures and a continuous decline in quality care. At the same time,
unlike many other aquatic habitats, springs are not included in the standard
assessment tools developed by the European Water Framework Directive (WFD).
Although, a large number of assessment methods developed for springs have
emerged since the 1990s, all existing assessment procedures apply to the mid-
European region, while for the Dinaric region appropriate assessment procedures
for spring habitats have not yet been developed. The aim of this paper is to show
the specific biodiversity and ecological characteristics of karst springs in Bosnia and
Herzegovina, their ecological status and sensitivity to the effects of anthropogenic
and climate changes and the possibilities of sustainable management of these
valuable resources.
