This study reports the levels and distribution patterns of some organochlorine pesticides (OCPs) in fish samples of the Gomti river, India, collected from three sites. In the fish muscles Sigma OCPs ranged between 2.58-22.56 ng g(-1) (mean value: 9.66 +/- 5.60 ng g(-1)). Neither spatial nor temporal trends could be observed in distribution of the OCPs. Aldrin was the predominant OCP, whereas, HCB and methoxychlor could not be detected. alpha-HCH and beta-HCH among the isomers of HCH and pp-DDE among the metabolites of DDT were the most frequently detected OCPs. The results revealed that the fish of the Gomti river are contaminated with various OCPs.
本研究报告了从印度戈姆蒂河三个采样点采集的鱼类样本中某些有机氯农药（OCPs）的含量水平和分布模式。在鱼肌肉中，总有机氯农药含量范围为2.58 - 22.56 ng g(-1)（平均值：9.66 +/- 5.60 ng g(-1)）。有机氯农药的分布在空间和时间上均未呈现出明显趋势。艾氏剂是主要的有机氯农药，而六氯苯和甲氧滴滴涕未被检测到。六氯环己烷异构体中的α-六氯环己烷和β-六氯环己烷以及滴滴涕代谢物中的对，对'-滴滴伊是最常检测到的有机氯农药。结果表明，戈姆蒂河的鱼类受到多种有机氯农药的污染。
