The results showed HCB and p,p′-DDE were detected widely in all shrimp samples.HCB residues in shrimp muscle ranged from nd to 13.2μg/kg and p,p′-DDE ranged from 0.790 to 5.82μg/kg. Much higherconcentration of OCPs was found in shrimp’s muscle of Lake Taihu than that of Lake Dongting. In addition, the levels of OCPs inshrimps muscle in dry seasons was little higher than in rainy season for two lakes. %R 10.18307/2009.0504 %U http://www.jlakes.org/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
