    ABSTRACT: A model based in an Artificial Neural Network (ANN) was developed in order to forecast the Olea airborne pollen concentration due to the allergenic power of its pollen grains. There were used daily data from Olea pollen and the main meteorological variables documented in the period 1993-2008. The model was carried out in the Spanish city of Ourense. The model was tested with data from 2009 and 2010, obtaining data with one day of anticipation. Obtained results could be employed in allergology and health sciences in order to prevent effect of pollinosis.

    ABSTRACT: Accumulation of copper, zinc, cadmium and lead in gill, liver, spleen, kidney and muscle tissues of Clarias gariepinus was studied after exposing the fish to 5 ppm Cu, 5 ppm Zn, 1 ppm Cd, 1 ppm Pb and to the same concentrations of their mixture over 1, 7 and 15 days. Atomic absorption techniques were applied in determining tissue metal levels. Highest Cu and Zn accumulation was observed in liver and kidney tissues at all exposure periods whereas highest Cd and Pb accumulation was in gill and liver tissues. The lowest metal accumulation was observed in muscle tissue. Accumulation of these metals in the tissues studied increased compared to control when exposed singly. Tissue accumulation of metals, however, decreased when exposed to metals in mixture compared with single exposures to metals. It was concluded that exposure to these metals in mixture had an antagonistic effect on metal accumulation.

    ABSTRACT: Abstract The study was carried out in Narta and Orikumi Lagoon (Vlora Bay), to evaluate their environmental status and to extent the pollution level by different contamination sources in these areas. Physico-chemical parameters (pH, dissolved oxygen, TSS, TDS, temperature, salinity etc), nutrient (N-NO3-, N-NO2-, N-NH4+ and P-PO43-) and heavy metals (Hg, Cu, Pb, Zn, Cr and Cd) content in water samples collected in Narta and Orikumi Lagoon were used for the assessment of the environmental situation of the lagoons. Samples were collected in ten sampling sites, five in each lagoon. A water sample collected in Vlora Bay was used as a comparative sample. Total dissolved metal concentrations were analyzed by graphite furnace AAS (for Pb, Cd, Cr, Cu, Zn determination) or CV-AAS (for Hg determination) known as a very sensitive analytical method. The trend of heavy metals content in water of the Lagoons resulted as following: Zn>Cu>Cd>Cr, Pb<Hg. Nutrients (N-NO3-, N-NO2-, N-NH4+ and P-PO43-) content was determined by spectrophotometric methods. The data matrix of analytical parameters was statistically treated with Descriptive Statistics and multivariate analysis by using MINITAB 17 software package. Based on the Cluster Analysis, the sampling stations were classified into 3 main clusters. Based on the results of physico-chemical parameters, nutrients and heavy metals content in studied areas, it is shown that Narta and Orikumi Lagoon are characterized by generally oligotrophic conditions and are suitable for fish growth. Keywords: Orikumi Lagoon Narta Lagoon, environmental situation, pollution, physical-chemical parameters, nutrients, heavy metals.

    ABSTRACT: Effects of copper (Cu) and lead (Pb) applied singly and in mixture with chitosan (CT) on sera aspartate aminotransferase (AST), alanin aminotransferase (ALT) activities, glucose, total protein and cholesterol levels of Clarias gariepinus were studied after exposing the animals to 5.0 ppm Cu and 1.0 ppm Pb singly and in mixture with 75 ppm Chitosan over 1, 7 and 15 days. Sera parameters were measured using an auto analyzer and statistical evaluation of the experimental data was carried out by Variance Analysis and Student Newman Keul’s Procedure (SNK). Abundant biosorbants such as chitin and chitosan are known to form stable complexes with many metal ions. Chitin is widely distributed in nature, especially in the exoskeletons of marine invertebrates such as prawn, crab and lobster whereas its derivative chitosan has reactive amino groups which forms complexes between metal ions and the polymer chain. No mortality was observed during the experiments. Exposure to Cu-CT mixture decreased sera glucose level at all exposure periods, sera cholesterol level on day 15, sera ALT activity on day 1 and sera total protein level on day 15 compare to Cu alone. Exposure to Pb-CT mixture decreased sera glucose, cholesterol levels and AST and ALT activities on day 15 compared with Pb alone. This might be due to chitosan has reactive amino groups which forms complexes between metal ions and the polymer chain.

    ABSTRACT: In a background of increasingly frequent and intensive Microcystis blooms occurred in eutrophic lakes, many countries, particularly China, have used filter-feeding fish to control algal blooms according to non-traditional biomanipulation theory. However, there is little information concerning the potential photosynthetic activity of cyanobacteria in the guts of planktivorous fishes. To make a scientific assessment of this algal control echnology, we evaluated the effects of digestion by two fish species, silver carp and bighead carp, on the growth potential of Microcystis blooms in terms of photosynthetic activity, metabolic activity, up-floating velocity, morphological size, and toxin production. The results showed that: 1) the potential photosynthetic activity of Microcystis dropped significantly in fish foreguts after ingestion, but gradually increased and recovered in the midgut and hindgut; 2) digestion by planktivorous fish could significantly decrease the colonial size and up-floating velocity of Microcystis; 3) selective digestion by bighead carp caused a sharp rise in cellular microcystin levels; and 4) Microcystis retained a high growth potential after digestion by filter-feeding fish. These results indicate that planktivorous fish could be used for controlling blooms due to the degree of digestion and long retention of Microcystis in fish guts, but the controlling effect was limited because the potential photosynthesis activity of algae gradually recovered along the gut sections and the digested algae could grow normally after subsequent release into lakes. In addition to being less effective at controlling algal blooms than silver carp, the digestion process in bighead carp might confer an advantage to toxic Microcystis species.

    ABSTRACT: Agave tequilana Weber leaves and fiber were studied as substrates for laccase production by Pleurotus ostreatus in a submerged culture, in order to take advantage of these agro-industrial wastes, which are generated during agave harvesting for tequila production. The optimal conditions for laccase production in submerged fermentation were met by a substrate concentration of 1% (w/v) at 120 h, producing 276.36 and 169.25 U L-1 for leaves and fiber, respectively [A1]. The addition of glucose did not significantly (p>0.05) affect enzyme production. A medium consisting of only water and agave leaves was the best culture broth for enzyme production, and this medium was selected for the study with the fluidized bed bioreactor scale. The specific activity for kinetic studies in a flask (50 ml working volume) was 14.68 U mg-1. In the reactor, the specific activities were 10.78, 1.09 and 1.74 U mg-1 for the first, second and third cycles of operation, respectively [ME2]. Thus, the leaf residues of A. tequilana generated by the tequila industry can be used as a substrate by P. ostreatus for laccase production without co-substrate addition.

    ABSTRACT: The popularity of landfill gas to energy projects increased worldwide as well as in Turkey in the last two decades due to the importance of renewable energy sources and the green house gas emission control in environmental protection. Many Waste-to-Energy (WTE) projects focus on methods that employ landfill gas (LFG) from landfills to produce electric power. Most of the projects refer to gas prognosis models such as USEPA-LandGEM, GasSim, EPER, and IPCC to determine the installation power capacity. However, problems related to landfill, power generation and energy delivery have limiting factors for landfill gas and energy production. In this study, the limiting parameters with their assessments are discussed for Odayeri and Kömürcüoda Sanitary Landfills, Istanbul, Turkey. To overcome these issues, several improvements were done such as top surface cover application to both landfill sites, buffer gas tank installation to minimize the fluctuation of LFG quality and reduction of leachate water level via pumping. Accordingly, an increase in the recovery of LFG has been accomplished. The recovery LFG rate to theoretical extractable LFG rate ratios reached to 75 % and 60% in 2012 for Odayeri and Kömürcüoda landfills, respectively.

    ABSTRACT: Rivers in semi-arid climates are extremely sensitive to hydrological and anthropogenic pressures. However, they have been poorly studied, especially in east Mediterranean countries. In Cyprus, the freshwater flora of fluvial corridors has not been extensively investigated. In this paper, an updated inventory of aquatic and riparian flora from permanent mountainous and temporary Mediterranean rivers of Southern Cyprus, is presented. During this study, a total of 57 stream sites located in 17 river basins were surveyed. The freshwater flora was surveyed during the vegetation periods (March to May) of the years 2007 to 2010 and a total of 97 aquatic and 169 riparian taxa were recorded. Among them, 22 taxa belonging mainly to charophytes and bryophytes floristic groups were reported for the first time in Cyprus. Aquatic and riparian species diversity was distributed unevenly in the investigated fluvial corridors of Cyprus. The maximum species number occured in Diarizos river (81) basin and the least (4) in Elias river. Overall, this work provides an updated inventory and an overview of plant diversity in the most important aquatic and riparian ecosystem, of the island and is aimed at providing the knowledge required to support conservation actions in the river basins of Southern Cyprus.
