Abstract

Due to mining and smelting processes in the Sar Cheshmeh region, in south western of Kerman province, a significant amount of sulfur dioxide (789 tons/day) and aerosols are emitted to the atmosphere. In order to investigate the effect of these emissions on acidity and chemical composition of precipitations in the studied region, pH and chemical composition of several precipitations (in the years 2005, 2006 and 2007) were determined in different principle geographic directions of the SAR CHESHMEH COPPER COMPLEX. The results show the occurrence of ACID RAINs in the Sar Cheshmeh region. Concentrations of major cations and anions in precipitations have the following sequences: Ca2+>Na+>NH4+>K+>Mg2+ and SO42->HCO3->Cl->NO3 and these concentrations (especially sulfate) are higher than usual amounts in the world. Results also show that precipitations in this region contain significant quantities of Cu, Pb, Zn and Cd and that intensity of pollution and acidity is higher in the north and northeastern part of the studied region that coincide with the main directions of wind. The heavy metal contents of the precipitations have the following sequence: Cu>Zn>Pb>Cd, and the sequence of their enrichment factor (E.f.) relation to global mean is as follows: Zn<Cd<Zn<Cu. Correlation between the HEAVY METALS abundances in snow and rain and their abundances in aerosols emitted from stacks as well as higher acidity and pollution in samples of northern and northeastern part of the studied region indicate that the main source of the pollution and acidity is the emissions from the smelter and other part of the SAR CHESHMEH COPPER COMPLEX.
