This paper examines the concentration levels of organochlorine pesticides (OCPs) such as hexachlorocyclohexane (HCH) (alpha, beta and gamma), Aldrin, Endosulfan (alpha, beta), DDE, DDD, and DDT in the leaf, root and sediment part of Avicennia marina, a dominantly distributed mangrove species in Mumbai. The overall pattern of accumulation of OCPs was observed as sigmaHCH> sigmaDDT> sigmaEndosulfan>Aldrin. The occurrence of alphaHCH was found to be frequent in all the samples. The leaf and root samples showed better uptake of organochlorine pesticides whereas lower concentration levels of OCPs was observed in case of sediment samples. The mean concentration of OCPs was observed highest in case of root samples. This study indicated towards the capability of A. marina in bioaccumulation of the OCPs. The present data will serve as the baseline against which future study of OCPs uptake in the mangrove plant species may be assessed.
本文研究了孟买主要分布的红树林物种白骨壤的叶片、根部和沉积物中六氯环己烷(HCH)(α、β和γ)、艾氏剂、硫丹(α、β)、滴滴伊、滴滴滴和滴滴涕等有机氯农药(OCPs)的浓度水平。观察到OCPs的总体积累模式为∑HCH>∑DDT>∑硫丹>艾氏剂。在所有样品中均频繁发现α-HCH的存在。叶片和根部样品对有机氯农药的吸收较好,而沉积物样品中OCPs的浓度水平较低。根样品中OCPs的平均浓度最高。本研究表明白骨壤具有生物累积OCPs的能力。目前的数据将作为基线,据此可评估未来红树林植物物种对OCPs吸收的研究。
