Residual levels, distribution and possible sources of organochlorine pesticides (OCPs) in nine water column and suspended particulate matter (SPM) samples collected from Xiangshan Bay, East China Sea were investigated. Total OCPs concentrations in water column and SPM ranges from 2.88 to 34.72 ng/L and 2.47 to 29.94 ng/L, respectively, which exceed the US Environmental Protection Agency regulatory limits. Moreover, low ratio of α-HCH/γ-HCH and high ratios β- and γ-HCH suggested the cocktail input pattern of fresh and weathered HCHs. Meanwhile, low ratio of (DDE + DDD)/DDT and high ratios p,p'- and o,p'-DDT reflected a "dicofol type DDT pollution" pattern.
本研究调查了取自中国东海象山湾的 9 个水柱和悬浮颗粒物（SPM）样本中有机氯农药（OCPs）的残留水平、分布情况和可能的来源。水柱和 SPM 中的总 OCPs 浓度范围分别为 2.88-34.72ng/L 和 2.47-29.94ng/L，均超过了美国环保署的监管限值。此外，α-HCH/γ-HCH 的低比值和β-和γ-HCH 的高比值表明了新鲜和风化 HCHs 的混合输入模式。同时，（DDE+DDD）/DDT 的低比值和 p,p'-和 o,p'-DDT 的高比值反映了“三氯杀螨醇型 DDT 污染”模式。
