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