应用地积累指数评价滇池沉积物中重金属污染
The Application of the Index of Geoaccumulation to Evaluate Heavy Metal Pollution in Sediments of the Dianchi Lake
摘要
Abstract
The contents of heavy metals and organic matter in surface sediments from 8 sections of the Dianchi Lake were investigated. The method of index of geo-accumulation was used to assess the heavy metals pollution (Cu, Zn, Pb and Cd). The results show that the concentrations of heavy metals ( except for Cd) were high in the sediments. In terms of concentration, the heavy metals followed a decreasing order of Zn > Cu > Pb > Cd in the sediments. Relativities between heavy metals and organic matter in the sediments were studied and found that relationship between them were insignificant ( except for Pb). In addition, the results also find that the pollution degrees of most of heavy metals were higher than moderate of them, and pollution degrees of the heavy metals followed the sequence of Cu > Pb > Zn > Cd.关键词
