应用地积累指数法评价南通市内河沉积物中重金属污染

摘要

The 51 sediment samples of Cu,Pb,Cr,Hg,As,Cd from Nantong City,tested heavy metal concentration,and evaluated the heavy metal pollution of river sediments by land accumulation index.The results showed that： Nantong City,sediment is basically non-heavy metal contamination,only the elements arsenic light pollution.%对南通市51个沉积物样品中重金属Cu、Pb、Cr、Hg、As、Cd的质量浓度进行了测试,并用地积累指数法评价了河流沉积物的重金属污染。结果表明：南通市沉积物重金属基本上未受污染,只有元素As受到轻度污染。
