Abstract

One of the major emission sources of some metals in the eastern part of the R. Macedonia is Bucim copper mine and flotation, near the town of Radovis. Ore excavation is from open pit and the ore tailings are stored in the open, in mine vicinity. The produced copper ore from the mine is processed in the flotation plant; after the flotation of copper minerals, the flotation tailings are separated, disposed of and deposited on a dump site in an adjacent valley near the village Topolnica. During the 35 years of continuous exploitation around the Buchim Mine was created surface waste dump were have been stored more than 150 Mt and more than 100 Mt material within the hydrotailling dam. Within this study a total content of 20 elements was determined in soil samples taken from the vicinity of the "Bucim" mine, covering an area of 14.2 km2. Analyses were performed by the ICP-AES. The results have been compared to new Dutchlist and NOAA standards and the following was concluded: As values ranged 13.1÷225 mg kg-1 with 20 samples above the optimum (29 mg kg-1 As) and 7 above action value (55 mg kg-1 As), in that context Cd values ranged 0.67÷17.9 mg kg-1 with 17 values above optimum (0.8 mg kg-1 Cd) and 1 over the action value (12 mg kg-1 Cd), Cr with range 0.1÷171 mg kg-1 with 6 over optimal value (100 mg kg-1 Cr) and none above action value (380 mg kg-1 Cr), Cu with range 17.8÷1734 mg kg-1 with 16 over optimal value (36 mg kg-1 Cu) and 3 above action value (190 mg kg-1 Cu), Ni with range 9.8÷69.4 mg kg-1 with 5 over optimal value (35 mg kg-1 Ni) and none above action value (210 mg kg-1 Ni), Pb with range 46÷3456 mg kg-1 with 19 over optimal value (85 mg kg-1 Pb) and 1 above action value (530 mg kg-1 Pb), Zn with range 88÷3438 mg kg-1 with 12 over optimal value (140 mg kg-1 Zn) and 1 above action value (720 mg kg-1 Zn), Mn with range 169÷998 mg kg-1 with 25 over optimal value (33 mg kg-1 Mn) and none above action value (48 mg kg-1 Mn), Fe range 0.73÷5.02% with 21 over optimal value (1.8% Fe) and none above action value (3.2% Fe). The V, Al, Co, also, showed some increased values, but not more than optimal concentration.
