A fugacity-based food web bioaccumulation model was constructed, and the biotic concentrations of butyltins in the food web of the Jincheng Bay mariculture area were estimated accordingly, using the water and sediment concentrations described in the accompanying paper (Part I). This paper presents an ecological risk assessment (ERA) and a human health risk assessment (HHRA) of the butyltins, based on the estimated tissue residues in the marine life in this area. The results showed that the ecological risk probability was greater than 0.05. At this level, management control is critical since sensitive marine species would be profoundly endangered by butyltin contamination. Few if any detrimental effects, however, would be generated for humans from exposure to butyltins through seafood consumption. The fugacity-based model can refine the ERA and HHRA of pollutants in marine areas, provide a basis for protecting marine ecology and the security of fishery products, and thus help determine the feasibility of a proposed aquaculture project.
构建了一个基于逸度的食物网生物累积模型，并利用随附论文（第一部分）中描述的水和沉积物浓度，相应地估算了金城湾海水养殖区食物网中丁基锡的生物浓度。本文基于该地区海洋生物中估计的组织残留量，对丁基锡进行了生态风险评估（ERA）和人类健康风险评估（HHRA）。结果表明，生态风险概率大于0.05。在此水平下，管理控制至关重要，因为敏感的海洋物种将受到丁基锡污染的严重威胁。然而，通过食用海鲜接触丁基锡对人类几乎不会产生任何有害影响。基于逸度的模型可以完善海洋区域污染物的ERA和HHRA，为保护海洋生态和渔业产品安全提供依据，从而有助于确定拟议水产养殖项目的可行性。
