According to the recent investigations, the terrains of the alluvial-Agricultural soils starting from the Ohis (organic chemical industry - Skopje), to East, North-east, South-east 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 t...

... [9][10][11][12] (Fig. 1). • In the frame of the alluvial-agricultural areas of the D. Lisice, G. Lisice, Dracevo and Ognjanci villages was performed top soil sampling (from the soil surface to a depth of ca 20-30 cm) inside of a systematic net of 333 × 333 m. Everyone soil sample represents actually an average sample of 5 top soil samples (Fig. ...

Jančev et al. (2010Jančev et al. ( , 2014 have published data for the contents of several elements in soils from the Skopje Valley (Pb, Zn, Cu, Ni, Cr, Ba, Y and As) determined by ESA method (emission spectral analysis) with much higher average and median values for most of these elements, which is as a result of the analytical technique applied. ...

Therefore the results present in this work are the first detailed data about the content of zinc in the soil of the city of Skopje. ...
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.

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.

... 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.
