烷基酚（AP）和双酚A（BPA）在鱼类、对虾和软体动物等海洋生物体内的分布可以直接有效地反映AP和BPA的暴露水平。本文首次报道了长江三角洲东海95个野生和88个加工海洋生物样品中4种AP（4-t-octylphenol，4-t-OP; 4-octylphengl，4-OP;4-nonylphenol，4-NP; 4-n-nonylphenol，4-n-NP）和BPA的种间分布和人体健康风险。4-NP是主要化合物，最高检出浓度为19，890.50 ng/g湿重。台州、上海和宁波出现严重污染。种内分布与食性、生活方式和营养转移有关。在食用底栖生物的鱼类或底层鱼类中观察到较高的4-t-OP、4-OP、4-n-NP和BPA残留浓度，而4-NP由于营养稀释而显示出不同的结果。线性AP（4-OP和4-n-NP）的营养放大因子（TMF）（1.22-2.93）高于分支AP（4-t-OP和4-NP）（0.72-0.90），说明线性AP的代谢相对稳定。4-NP具有0.72的最低分散力值，并且可以观察到其营养稀释，因为与其他AP相比，支链碳链表现出最低的分散力。就健康风险而言，7岁儿童可能暴露于4-NP的最高健康风险，其危险商数的第95百分位值为022至0.23;而其他化学品的风险相对较低。(C)2015 Elsevier B.

The distributions of alkylphenol (AP) and bisphenol A (BPA) in marine organisms, including fish, prawns and molluscs, could reflect the exposure of AP and BPA directly and effectively. This paper provides the first report on the species-dependent distribution and the human health risks of four APs (4-t-octylphenol, 4-t-OP; 4-octylphengl, 4-OP;4-nonylphenol, 4-NP; 4-n-nonylphenol, 4-n-NP) and BPA in 95 wild and 88 processed marine biota samples from the East China Sea of the Yangtze River Delta area. 4-NP was the predominant compound with the highest detected concentration of 19,890.50 ng/g ww. Significant pollution was observed in Taizhou, Shanghai and Ningbo. The species-dependent distribution was related to food habits, living patterns and trophic transfer. Higher residual concentrations of 4-t-OP, 4-OP, 4-n-NP and BPA were observed in fish species that consumed benthic organisms or demersal fish species, whereas 4-NP showed different results due to trophic dilution. The trophic magnification factors (TMFs) of the linear APs (4-OP and 4-n-NP) (1.22-2.93) were higher than those of the branched ones (4-t-OP and 4-NP) (0.72-0.90), indicating the relative metabolism stability of linear APs. 4-NP has the lowest TMF value of 0.72, and its trophic dilution might be observed because the branched carbon chain exhibits the lowest dispersion force compared to that of the other APs. As for the health risk, 7-year old children may be exposed to the highest health risk of 4-NP with 95th percentile values of the hazard quotient of 022 to 0.23; however, the risks of the other chemicals were relatively low.
