| Abstract: | The organochlorine pesticides(OCPs) were analyzed in the surface sediments of Lake Bosten in Xinjiang Uygur Autonomous Region,and distribution characteristics,sources and ecological risk were evaluated.The results showed that the concentration rang of total OCPs in sediments was 2.15-16.80ng/g.Chlordane and DDTs had higher concentrations than other pesticides.The concentration range of Chlordane and DDTs were 0.12-12.08ng/g and 0.42-5.13ng/g,respectively.The total OCPs contents of Lake Bosten decreased from... |
