摘要
本研究采集的沉积物样品中均能检测到HCH、DDT等有机氯农药,但不同种地区的沉积物,农药含量差异较大,且湖泊沉积物中有机氯农药残留普遍存在。分析结果表明:HCHs来源于林丹,DDTs主要代谢产物为DDE,HCB残留难以降解。
The study of sediment samples were collected to detect organic chemicals, such HCH, DDT, but the sediment pesticide content have some differences in regions of Poyang Lake, and it is u- biquitous in lake sediments of Organochlorine pesticides residues. The analysis results showed that HCHs comes from Lindane,DDE comes mainly from DDTs metabolites,and HCB residues for DDE degraded.
