The alluvial agricultural top soil samples of the Skopje field territory (of cca. 300 km2 - total surface) were investigated by the regional eco-geochemical mapping on the heavy-toxic metals: Pb, Zn, Cu, Ni, Cr, Ba, Y, As, determined by the emission spectral analyses. According to the achieved results were determined as follows: (1) contaminations...

The role of migration in the spread of HIV in sub-Saharan Africa is well-documented. Yet migration and HIV research have often focused on HIV risks to male migrants and their partners, or migrants overall, often failing to measure the risks to women via their direct involvement in migration. Inconsistent measures of mobility, gender bias...

The results of the spatial distribution of zinc in topsoil (0–10 cm) over the city of Skopje, Republic of Macedonia, are reported. The soil samples from 233 previously defined locations in the study area were collected. Inductively coupled plasma – atomic emission spectrometry (ICP-AES) was applied for the determination of zinc. Data analysis and construction of the map were performed using the Statistica (ver. 9), AutoDesk Map (ver. 2008) and Surfer (ver. 9) software’s. It was found that the median content of zinc in the topsoil for the entire study area is 100 mg/kg (with a range of 23–18000 mg/kg) which exceeds the estimated Macedonian and European zinc median contents in topsoil by a factor of 1.2 and 1.9, respectively. It is evident that the content of zinc is high in the topsoils from the industrial areas (156 mg/kg) exceeding the target value of Dutch standards (140 mg/kg) which is a result of contamination, mainly by dust from the iron and steel works.
... The micro locality E-NE-SE around the OHIS factory is select, due to the indication of contamination of the soil with arsenic of anthropogenic origin from the previously realized preliminary research [1][2][3]. This is a consequence of long term production of pesticides by OHIS factory in which arsenic compounds have been used as active components, but it is also due to decades long use of agrochemical additives during agricultural activities. ...
The soils are continually contaminated with increasing contents of heavy toxic metals of anthropogenic origin that have negative influence on the eco system. In the focus of this research is arsenic as one of the most characteristic anthropogenic pollutants in soils. Research area is selected as part of Skopsko Pole i.e. agricultural micro locality near to the urban centre, where anthropogenic contamination of the soil with arsenic was evident. The ICP-AES analyzis have been applied for determination of the content of arsenic in various horizons of soil, up to 1 meter depth. The content of arsenic in various minerals in the soil as well as quantity of water soluble arsenic have also been determined. The basic aim was to define mechanisms and intensity of migration of arsenic in the soil. The type of soil from the micro locality which is dominantly consisted of coarse grained quartz and fine grained clay along the whole profile, and its physical and chemical properties, enable intensive and free migration of micro elements in soluble and fixed form.

In the soil from the micro locality E-NE-SE around the OHIS factory, an increased degree of contamination with arsenic of anthropogenic origin has been detected. The objective of this research is an integral perception of the soil state with this pollutant, aiming to determine options for remediation of the contaminated soil. The basic parameters are being monitored for the extracted quantities of arsenic from various plant species that exist at the micro locality, in correlation with soil composition in the medium of the root system and the external factors. Intention is to define the affinity of the existing plants for available forms of arsenic. Two natural inorganic raw materials have been appointed as potential materials for remediation of contaminated soil with arsenic from the micro locality: diatomaceous earth from the locality of Slaviško Pole and trepel from the locality of Suvodol. Applying the extractors, their appropriate selective affinity and capacity for arsenic and other micro elements is evident.

According to the regional geo-chemical mapping 1-3 (top soil samples taken in a systematic net (1 × 1 km) performed in 2009 year from Skopje field territory), was determined that in the top soil samples from the micro localities around the D. Lisice, G. Lisice, Dracevo and Ognjanci villages there are increased As contents (higher than 20 ppm that is in a range of 20-60 ppm) ( . As a result of the aforementioned data, in the progress of 2010 year was performed a more detailed geochemical mapping (sampling inside of a systematic net of 333 × 333 m) inside agricultural-alluvial areas of the mentioned villages [9][10][11][12] (Fig. 1). • Inside the treated area were taken 249 samples. ...
According to the recent investigations, the terrains of the alluvial-agricultural soils starting from the Ohis (organic chemical industry – Skopje), to East, Northeast , Southeast that is to the areas around the D. Lisice, G. Lisice, Dracevo and Ognjanci villages near Skopje, Macedonia, are treated as contaminated areas from As point of view. In the treated top soil samples from the mentioned region was discovered increased frequency of As contents in the range of 20–40 ppm as well as increased data for the arithmetic mean (about 25 ppm), geometric mean (19 ppm), and median (20 ppm).

Our research was carried out in the field and in the laboratory, in order to identify and to establish the soil properties and also to identify the type of soils from the research area. soil samples were collected from all the four locations in the timis county: Surduc, Liebling, Pischia, Sanandrei, on the entire soil profile and were analysed according to the national and international methodology 9 . soil pH was determined by potentiometric method, in water extract 1:2.5 ratio. ...
This paper presents chemical properties and fertility of soils which have been identified in the proximity of reservoirs in the Timis county: Murani-Pischia, Liebling, Surduc and Sanandrei. These lakes are representative for the Timis comity, because they occupy the largest areas. To determine the fertility potential of these soils soil samples were collected, which were analysed according to the specifical methodology for soil science laboratories. These soils have some particular properties due to their location in the proximity of the lakes mentioned above. According to the Romanian Soil System Taxonomy published in 2012, it were identified the following soils: Luvic Phaeozems, Stagnic Luvisols, Pellic-gleyic Vertisols and Haplic Luvisols. These soils are representative for the studied area, because they occupy the largest surfaces.
... With the aim of getting the idea of the terrain's real condition Jancev et al., 2007), there has been realized a project for preparing a geochemical atlas of heavy toxic metals for the territory of Skopsko Pole, with investigated area of more than 300 km 2 . In this research there has been put a particular accent on Arsenic (As), as one of the most common soil contaminants (Shacklette et al., 1974), as well as for the existence of relative assumptions of its increased concentration in some micro-localities (Jancev et al., 2010). ...
Arsenic, as the most common soil contaminant, was the subject of our research, presented in this publication. Namely, at the previous construction of the geochemical atlas of the presence of heavy toxic metals in the Skopje region soil, the area of about 300 km 2 has been explored. The analysis has been performed applying a semi quantitative method of ESA (Emission Spectral Analysis). The minimal detection limit for arsenic of this method is 100 ppm, so the obtained results did not show any value exceeding the previously pointed. Having in mind the probability of anthropogenic pollution of some segments of Skopje valley with arsenic, we enlarged our investigation as second phase of investigation applying the method of ICP-MS (Inductively Coupled Plasma-Mass Spectrometry). According to this method the minimal detection limit for arsenic is 1 ppm, and four micro-localities of increased arsenic content were considered. In third phase has been a process of detailed grid analysis of arsenic contents in the top soil samples of specific micro-localties. With a statistical processing of data the following values of statistical parametres have been evaluated: number of samples (500), minimal detected content (< 0,3 ppm), maximal detected content (244,7 ppm), arithmetic mean (19 ppm), geometric mean ( 16 ppm), median ( 16 ppm), mean ( 16 ppm), standard deviation (1,8 ppm); threshold ( 20 ppm), threshold's double value (40 ppm); threshold's four times value (80 ppm); anomalous mean (> 80 ppm). The comparative frequency polygon, as well as the comparative diapason diagram were constructed.
