| 摘要: |
| 使用气相色谱质谱技术测定了青虾肌肉组织中的8种有机氯农药,包括六氯苯、氯丹、滴滴涕(∑DDTs)、艾氏剂、狄氏剂、异狄氏剂、七氯和灭蚁灵.对太湖和洞庭湖15个点位29组野生青虾样品的测定结果显示,青虾肌肉组织内残留的有机氯农药主要是六氯苯和滴滴涕,六氯苯含量为nd-13.2μg/kg(湿重),滴滴涕含量为0.790-5.82μg/kg(湿重).洞庭湖青虾肌肉中有机氯农药的含量略高于太湖青虾,两湖青虾肌肉残留有机氯农药在枯水期时的含量多数大于丰水期时的含量. |

| Abstract: |
| Twenty-nine shrimp samples from 15 sites in Lake Taihu and Lake Dongting were collected and measured, and 8 kinds oforganochlorine pesticides (OCPs) in wild shrimps muscle tissue were analyzed with Gas Chromatography/Mass Spectrometry.Hexachlorobenzene(HCB), Chlordane, ∑DDTs(p,p′-DDT、 o,p′-DDT、 p,p′-DDE、 o,p′-DDE、 p,p′-DDD、 o,p′-DDD), Aldrin, Dieldrin,Endrin, Heptachlor and Mirex were quantified. 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. |
