Abstract

The aim of this study was to investigate the distribution of some heavy metals in soil focusing on the identification of natural, industrial and anthropogenic element sources of pollution of the TEPP Oslomej (coal mine), in the Kichevo area, Macedonia. During the period of April 2012,2013 to May 2014, field and analytical studies of 12 sites (localities) in the region of Kichevo valleywere made at three different distances (three zone) from the source of pollution, the Thermal Power Plant(TPP) Oslomej. In April 2012,the localities and researchpoints at different distances from the source of pollution (TEPP-Oslomej) were determined. Research study includes determination of concentration of seven heavy metals: Ni, Cu, Zn, Fe, Mn, Cd and Pb in the soil samples. The content of the available heavy metals in the soils was carried out with DTPA-diethylenetriamine pentaacetic acid (DTPA diethylenetriamine pentaacetic acid) method (Lindsay and Norvell 1978; Page 1982). The content of heavy metals in the resulting solutions is determined by atomic absorption spectroscopy with Agilent 55A. According to the obtained graphs or by visual analysis, it was noticed that in most of the heavy metals (total and available forms) there is a reduction of the content from the first (closest) to the second zone. For some of the elements, higher concentrations were found in the third zone due to the natural geological composition and the reduced influence of TЕPP Oslomej. Heavy metals Pb and Cd are included in the group of toxic elements if they are introduced into the body in high concentrations or through products with higher values for the MDC. Chemical analyzes were conducted at Laboratory for Plant Ecology at the Institute of Biology, Faculty of Natural Sciences and Mathematics, Skopje using Atomic Absorption Spectroscopy (AAS) – flame and graphite furnace.
