扬州市工业用地重金属污染潜在生态危害分析

摘要

By application of potential ecological risk index, heavy metal pollution of an industrial park in Yangzhou city was analyzed. The result showed that there was obvious potential ecological risk resulting from industrial discharge. Of the all observed points, there were six points where the potential ecological risk indexes ranged in middle or high levels, accounting for 30% of all points. As to the proportion of potentially harmed area by different metals, they were 95% for Cd, 45% for Hg and 5% for Pb, which needed to pay sufficient attention.%应用潜在生态危害指数法,分析扬州某工业开发区土壤重金属污染状况,结果表明,由于工业排放造成的重金属潜在生态危害十分明显:综合各金属危害来看,有6个点位潜在生态危害指数处于中等到强水平,占比30%;区分各重金属造成的潜在生态危害面积,Cd占比95%,Hg占比45%,Pb占比5%.需引起足够重视.
