The concentrations of heavy metals (Cd, Pb, Cr, Ni, Cu, Zn, Hg and As) in surface sediments and bivalve mollusks in Kaozhouyang Bay were investigated. A biological risk analysis of the sediments indicated that ten sites (about 76.92% of the total number of sites) had a 21% incidence probability of toxicity. A health risk analysis of the bivalve mollusks indicated that Cu and As posed low risks to consumer health. On the basis of the target hazard quotient (THQ), adverse effects may occur based on total THQ (TTHQ). The highest TTHQ was found in the species, Ostrea rivularis, which had the highest capacity for the bioaccumulation (factor > 38) of Cd.
研究了高州洋湾表层沉积物和双壳类软体动物中重金属（Cd、Pb、Cr、Ni、Cu、Zn、Hg 和 As）的浓度。对沉积物的生物风险分析表明，有 10 个地点（约占总地点数的 76.92%）的毒性发生概率为 21%。对双壳类软体动物的健康风险分析表明，Cu 和 As 对消费者健康构成低风险。基于目标危害系数（THQ），总 THQ（TTHQ）可能会产生不良影响。在物种中发现最高的 TTHQ，Ostrea rivularis，其对 Cd 的生物积累能力最强（因子 > 38）。
