Determination of heavy metals contents and evaluation of contamination in soil of Anhui Dongzhi Xiangyu Chemistry Industrial Zone

WU-Lin,XIAO-Pu,ZHANG-Wei,ZHU LU-Sheng (Anhui Institute of Environmental Science,Anhui Hefei 20061)  
Five soil samples were collected in the Chemistry Industrial Zone of Anhui Dongzhi Xiangyu.Cd、Pb and Cr concentrations were analyzied in order to understand their accumulation extents.Environment quality evaluation was conducted adopting the single factor index and the potential ecology risk index(RI).Results showed that although Cr has the highest concentration,which is above 10 times of the background value,but with a small RI.On the contrary,Cd accumulated only 2-3 times of the background value but has the highest RI.Furthermore,Pb has showed pollution to some extent.Therefore,reasonable guidance of the regional development action can avoid the soil environment to get worse.
