Organochlorine pesticides (OCPs) in sediment, water and biota samples from the coastal marine environment of Mumbai were analysed to elucidate their distribution in various environmental compartments. HCH isomers, dichlorodiphenyltrichloroethane (DDT) and its metabolites were the predominantly identified compounds in all the samples. High ratios of DDT to dichlorodiphenyldichloroethylene (DDE) were found in seawater samples. This indicates the presence of a significant source of DDT in this region. In sediment samples, the gamma-isomer contributed almost 55% to the total HCH, indicating a high affinity of the gamma-isomer towards the sediment. The levels of organochlorines in fish obtained from this region were found to be lower than the levels of organochlorines in fish in temperate regions.
对孟买沿海海洋环境的沉积物、水和生物群样本中的有机氯农药（OCPs）进行了分析，以阐明它们在不同环境介质中的分布情况。六氯环己烷异构体、二氯二苯三氯乙烷（DDT）及其代谢物是所有样本中主要鉴定出的化合物。在海水样本中发现DDT与二氯二苯二氯乙烯（DDE）的比例很高。这表明该地区存在大量DDT来源。在沉积物样本中，γ-异构体占六氯环己烷总量的近55%，表明γ-异构体对沉积物具有高亲和力。发现该地区鱼类中的有机氯含量低于温带地区鱼类中的有机氯含量。
