Abstract:The content of Hg,As,Cu,Zn,Ni,Cr,Pb and Cd in the soil of twentyfive largescale enterprises in five key industries in Hubei Province was determined.The Nemerow pollution index and Hakanson ecological risk index evaluation methods are applied to evaluate the determination results of eight heavy metals in the soil.The results showed that the proportion of monitoring sites in the soil around the five key industries that are not polluted by heavy metal was less than 50.0%-87.5%,and the proportion of monitoring sites with slight potential risks of heavy metals was 37.5%81.5%.In the two enterprisesmineral mining and smelting as well as chemical raw material and chemical manufacturing,the maximum concentration of Cd is 10.3 mg/kg and 4.5 mg/kg respectively,and As is 114.0 mg/kg and 766.0 mg/kg respectively.The soil is contaminated by heavy metals with a moderate contamination of 3.6% and 5.6%,a severe contamination of 7.1% and 5.6% respectively.7.1% and 2.9% of the monitoring soil around the two enterprises are facing seriously potential ecological risks of heavy metals.
