摘要

小龙虾、鲤鱼和螃蟹因富含有毒元素而威胁着消费者的健康。对这些水体中有毒元素(As、Cr、Cd和Pb)的浓度同时就地调查较少。本研究采用电感耦合等离子体质谱法(ICP-MS)对来自湖北汉川同一地点的水产品中有毒元素进行了测定,以评估4种有毒元素在水产品中的富集程度及对消费者的健康风险。结果表明,除螯虾中Cr外,肌肉中其余各元素的含量均低于肝胰脏/肝脏。此外,小龙虾和螃蟹的肝胰脏中镉的浓度超过了中国和欧盟的标准。因此,不建议食用小龙虾和螃蟹的肝胰脏。小龙虾、鲤鱼和螃蟹肌肉中这些元素的估计日摄入量均未超过临时可耐受日摄入量,相应的目标危害商(THQ)和致癌风险(CR)值分别小于1和1 × 10-6。然而,三种淡水捕获的肌肉的累积消耗可能导致总THQ值显著增加。这些捕获物的肌肉的总摄取量应该是有限的。总的来说,这些发现可能会重新引起人们对食品安全和因消耗淡水渔获物而对人类健康造成的风险的关注。

Comparison of the health risks associated with exposure to toxic metals and metalloids following consumption of freshwater catches in China
Crayfish, carp, and crab threaten the consumer’s health due to the enrichment of the toxic elements. The concentration of the toxic elements (As, Cr, Cd, and Pb) in these aquatics was less investigated simultaneously in situ. In this study, the toxic elements in these aquatics from the same site of Hanchuan, Hubei Province, China were measured by ICP-MS to assess the enrichment of the four toxic elements in them and the health risk to the consumer. The results showed that the concentrations of these elements in muscle were lower than those in hepatopancreas/ liver, except for Cr in crayfish. Furthermore, the concentrations of Cd in the hepatopancreas of crayfish and crab exceeded the standards of China and the European Union. Accordingly, the hepatopancreas of crayfish and crab are not recommended for consumption. The estimated daily intake of these elements in the muscle of crayfish, carp, and crab did not exceed the provisional tolerable daily intakes, the corresponding target hazard quotient (THQ), and the cancer risk (CR) values for As were lower than 1 and 1 × 10–6, respectively. However, the accumulated consumption of the muscle of the three freshwater catches could result in a significant increase in the total THQ value. The total ingestion of the muscle of these catches should be limited. Collectively, these findings may renew interest in food safety and the health risk to humans owing to the consumption of freshwater catches.
