  • 摘要: 为了解珠江口生物中新增持久性有机污染物多氯萘（PCNs）、六氯丁二烯（HCBD）和五氯苯酚（PCP）及其醚类（五氯苯甲醚，PCA）和酯类（月桂酸五氯苯酯，PCPL）的污染特征，本研究采集了珠江口鱼类、甲壳类（虾和蟹）和贝类（牡蛎）等生物样品，并分析了这些样品中PCNs、HCBD、PCP、PCA和PCPL的含量.珠江口牡蛎样品中PCNs的浓度（32-77 ng·g-1脂重（lw））显著高于鱼类样品（3.0-27 ng·g-1 lw）和甲壳类的虾蟹样品（2.7-29 ng·g-1 lw）（P-1 lw，平均值为1.8±1.4 pg·g-1 lw，高于鱼类和虾蟹样品；PCN73是珠江口生物样品毒性当量的主要贡献者（60.8%-99.8%）.珠江口生物样品中HCBD的浓度为n.d.-0.99 ng·g-1 lw，不同生物样品中HCBD的浓度没有显著性差异（P>0.05）.PCA在生物样品中检出率高于PCP和PCPL.与其他研究相比，珠江口生物样品中PCP的浓度（n.d.-100 ng·g-1 lw）处于中等偏低水平.
    Abstract: Concentrations and distribution characteristics of polychlorinated naphthalenes (PCNs), hexachlorobutadiene (HCBD), pentachlorophenol (PCP), pentachloroanisole (PCA) and pentachlorophenyl laurate (PCPL) were analyzed in fish, crustacea (prawns and crabs) and shellfish (oysters) samples collected from the Pearl River Estuary (PRE). PCN concentrations in oysters ranged from 32 ng·g-1 lipid weight (lw) to 77 ng·g-1 lw, which were significantly higher than those in fish (3.0-27 ng·g-1 lw) and crustacea (2.7-29 ng·g-1 lw) (P4PCNs (the sum of PCN2, PCN6, PCN13 and PCN28) ranging from 76% to 99%. The toxic equivalent quantities (TEQs) of PCNs in oysters varied from 0.03 pg·g-1 lw to 4.4 pg·g-1 lw (average:1.8±1.4 pg·g-1 lw), which were higher than those in fishes, prawns and crabs. PCN73 contributed the most to the total PCN corresponding TEQs, with percentages of 60.8%-99.8%. HCBD in biota samples varied from n.d. to 0.99 ng·g-1 lw, and no significant differences were observed among three species investigated (P>0.05). PCA was more frequently detected than PCP and PCPL in all the samples. In global comparison, PCP concentrations in the biota samples of this study were at low-to-middle levels.
