Paper Title:
Characteristics of Organchlorine Pesticides in Sediments of Lianhuan Lake
  Abstract

In this study, sediment samples were collected in Huoshaohei (HSH), Xihulu (XHL), Amuta (AMT), and Talahong (TLH) of Lianhuan Lake. Eleven chemical compounds of OCPs measured using GC-ECD method in the study area, including four HCH isomers (α-HCH, β-HCH, γ-HCH, δ-HCH), three DDT homologues (p,p’-DDT, p,p’-DDD, p,p’-DDE), Aldrin, Dieldrin, Endrin and Heptachlor. The ratio of (DDE + DDD)/∑DDT, the content of ∑HCH and ∑DDT, the correlations among TOC, ∑HCH, ∑DDT and OCPs were analyzed. The results show that HCHs and DDTs are major elements in this region and δ-HCH is the most dominant isomer in HCH, which was evidence of recent input of lindane. And higher amounts of OCPs occur in sediments with higher TOC content, DDTs and HCHs have similar sources which may come from usage of lindane and DDT in recent years.
