%X This study analyzed chlorinated pesticides of sediments in Taihu Lake. The DDT, DDE, DDD, HCH isomers, Aldrin, Diddrin, Hexachlorobenze, Heptachlor were measured in all samples. beta-HCH, p, p'-DDE and Hexachlorobenze had higher concentrations than others. The average values of them were 6.572 ng/g, 1.432 ng/g and 2.158 ng/g, respectively. HCHs in sediments were higher than DDTs. The organochlorine residues in sediments mainly originated form the runoff, atmospherically deposition and industrial sewage. HCHs and DDTs of sediments in Taihu Lake were higher than those of sediments in Chinese rivers, but lower than those of bays reported in some papers. According to the ERL and ERM value of risk evaluation for ocean which can also be applied for lake, sediments in Taihu Lake pose a low risk to consumers of bottom feeders.
