Distribution and risk assessment of toxic metal pollution in the soil and sediment around the copper mine

Background: Industrial pollution of metals is a serious environmental concern. The presence Sarcheshmeh copper (Cu) mine and the possibility soil pollution, were primary motivations for evaluating heavy in this area. Methods: A total 171 10 sediment samples collected randomly from study area Cu, aluminum (Al), molybdenum (Mo), lead (Pb), cadmium (Cd) determination. USEPA method was used to acid digest samples, present detected using atomic absorption spectroscopy. Results: By measuring metal concentrations calculating geo-accumulation index (Igeo), enrichment factor (EF), contamination (CF), level by assessed. It found that contaminated with Cu decreased Rafsanjan city, indicating anthropogenic. has not been poisoned Al or non-natural states because it alkaline. Sediment less than moderately polluted Mo Pb, but Cd more problematic. Conclusion: Increasing distance resulted decrease toxic concentration. concludes monitoring filtering wastewater mine, caused trace elements can be greatly reduced.
