水产品中有毒金属含量的增加已成为一个普遍的负担，因为这些产品的消费对水生生物和人类健康造成了风险。本文研究了长江下游重要经济和食用鱼类和双壳类动物体内有毒金属的分布和积累，并探讨了其对人体健康的危害。一般来说，内脏和鳃显示出比其他组织更高的金属浓度。鱼类和贝类肌肉组织中重金属的富集顺序分别为Zn > Cu > Mn > Cr > As > Hg > Pb > Cd和Mn > Zn > Cu > As > Cr > Pb > Cd > Hg。鳃组织中Mn（507.50 μg g g-1）和Pb（0.51 μg g g-1）的最大积累表明这些金属主要从水体中吸收。根据危害指数（HI）计算（基于美国环保局），所分析的金属不会对正常和习惯性鱼类消费者造成任何有害健康影响，但汞和砷除外，如果习惯性消费者大量食用这些物种。与中国食品卫生标准和其他国际标准（WHO/FAO）相比，研究物种的可食用肌肉组织中的金属含量低于可接受水平，并发现适合人类食用。
Increasing toxic metal content in aquatic products has become a universal burden due to the risks to aquatic organisms and human health associated with the consumption of these products. In this study, toxic metal distribution and accumulation in the organs of fish and bivalve species of economic and culinary importance from the lower reaches of the Yangtze River are examined, and the corresponding health risks are also investigated. In general, the viscera and gill show higher concentration of metals than other tissues. The order of the accumulation sequence of metals in muscle tissue of fish and bivalve is Zn > Cu > Mn > Cr > As > Hg > Pb > Cd and Mn > Zn > Cu > As > Cr > Pb > Cd > Hg respectively. Maximum accumulation of Mn (507.50 μg g-1) and Pb (0.51 μg g-1) in the gill tissues indicates the major uptake of these metals from the water column. According to the Hazard Index (HI) calculations (based on USEPA), the analyzed metals will not cause any harmful health effects to individuals for both normal and habitual fish consumers, except for Hg and As in habitual consumers, if these species are consumed at a larger amount. Compared to the Chinese Food Health Criterion and other international standards (WHO/FAO), metal concentrations in the edible muscle tissues of the studied species are lesser than the acceptable levels and found to be fit for human consumption.
