ABSTRACT
A study on the effects of lead and zinc mining and smelting activities on soil
environment in and around Mitrovica area, one the largest and richest mining district in the Republic of Kosova was carried out. The levels of antimony were determined in the 156 soil samples (depth 0-5 cm) using mass spectrometry with inductively coupled plasma (ICP-MS). The average Sb level in the soil for the entire investigated area (301.5 square kilometres) amounted to 2.3 ppm with a range from 0.10 to 1506 ppm. The highest content of Sb was found in the urban soils taken in the town of Zvecan, (ranged from 80.1 to 1506 ppm) and average value of 190 ppm exceeds the European average value for 316 times; in urban soils taken in the city of Mitrovica the Sb average value of 7.9 ppm (and the ranges from 18.1 to 27.4 ppm) exceeds the European average value for 13 times. Relatively high content of Sb ranging from 1.3 to 9.9 ppm were also found in soils taken around the “Trepca” mine in Stan Terg and in alluvial plains of the Sitnica River (ranges from 0.9 to 25 ppm). There was a zone of 102.5 km2 contaminated with Sb high level (above 3 ppm), while in southern part of the investigated area (city of Vushtrri) soils are less affected with potentially emission sources of Sb. This indicates that the concentration of Sb in the investigated soils is of anthropogenic origin and not natural. There is evidence showing that spatial distribution of Sb in contaminated soils is similar to As with which it is often associated in nonferrous ores. It can be concluded that long-term of the lead and zinc mining and smelting activities was the cause for the soil contamination with Sb in this area.
