摘要: Continuous deposition from Khatoon Abad smelter stack particulates has resulted in trace elements contamination soil. To investigate the regional distribution and fractionation of soils, soil samples were collected examined. The results demonstrate that highest element concentrations top are: >10000 mg Cu kg-1, 2000 Mo Zn 2694.2 As 2006.2 Pb 420.4 Sb 90.7 Cd kg-1. are much higher than normal uncontaminated geochemical background. most contaminated areas located vicinity prevailing wind directions. Calculated geoaccumulation index load indicate surface enrichment potentially toxic metals (Cu, Mo, As, Sb, Cd, Zn, Pb). Combined multivariate statistical geostatistical methods successfully separate contaminant (As, Cu, Pb, Zn) ones (Al, Fe, Mn, Cr). Furthermore, it was found mainly come copper smelter. modified BCR three-step sequential extraction technique applied to assess four fractions (residual, acid, reducible oxidizable) dust samples. a high proportion is extracted mobile fractions, indicating mobility probably hazardous environmental consequences.
