关 键 词：Dexing copper mine rainwater pipe sediment heavy metal pollution risk evaluation Index of geoaccumulation
摘 要：The sediment in the rainwater pipe network in Dexing copper mine area was selected as the research *** ICP-MS to determinate the 6 kinds of heavy metals content in sediments at 16 samplings,the measured data were analyzed in comparison with the national standard for soil environmental quality,and the geological accumulation exponential method was used for evaluating the heavy metals in *** results showed that the content of Cu and as exceeded the national grade III soil quality standard in many areas,but the regional difference was not *** content of Cd exceeds the national grade III soil quality standard in some regional samples,and its spatial distribution features were very *** total amount of Cr,Zn and Pb was lower than the national grade III soil quality *** was found that the pollution degree of Cd was the most serious,followed by Cu and As,Cr,Zn and Pb with the assessment by Index of geoaccumulation.
