Bioenrichment preference of arsenic and metals in wild marine organisms has been scarcely considered. Twenty species including fishes, cephalopods, crustaceans, and bivalve mollusks were collected from Dapeng (Mis) Bay and analyzed for arsenic and metals. Through this study, we had obtained the following four main conclusions: (1) average concentrations of arsenic and metals (μg/kg, wet weight) in the aquatic organism samples were 48.7 for Cr, 1762.0 for Mn, 20,632.8 for Fe, 33.0 for Co, 119.5 for Ni, 3184.7 for Cu, 12,040.5 for Zn, 389.0 for As, 189.1 for Se, 144.4 for Cd, 15.0 for Hg, and 55.3 for Pb; (2) factor analysis (FA) revealed that the studied twenty species exhibited three types of arsenic and metal bioenrichment preference;(3) non-carcinogenic health risk assessment indicated insignificant health effects from marine organism consumption; (4) carcinogenic health risk assessment revealed an unacceptable risk from consumption of nine species, seven of which were crustaceans.
野生海洋生物对砷和金属的生物富集偏好很少被考虑。从大鹏（米）湾采集了 20 种包括鱼类、头足类、甲壳类和双壳类软体动物，用于分析砷和金属。通过这项研究，我们得出了以下四个主要结论：(1) 水生生物样品中砷和金属（μg/kg，湿重）的平均浓度分别为 Cr 48.7、Mn 1762.0、Fe 20632.8、Co 33.0、Ni 119.5、Cu 3184.7、Zn 12040.5、As 389.0、Se 189.1、Cd 144.4、Hg 15.0 和 Pb 55.3；(2) 因子分析（FA）显示，研究的 20 种生物表现出三种类型的砷和金属生物富集偏好；(3) 非致癌健康风险评估表明，食用海洋生物不会产生显著的健康影响；(4) 致癌健康风险评估显示，九种物种的食用存在不可接受的风险，其中七种是甲壳类动物。
