Abstract:

Mining, chemical industry, metallurgy, agricultural cultivation discharge heavy metal pollutants into rivers, lakes and seas, resulting in heavy metal residue pollution of fish. Heavy metal residues in fish have the characteristics of enrichment, biological toxicity, and persistence, and are difficult to degrade through their own actions. It not only threatens the development of fisheries and the health of aquatic ecology, but also the safety of human diet. The article categorizes the accumulation characteristics and summarizes the accumulation patterns of metal residues in fish. Furthermore, the sources, occurrence, and migration and transformation patterns of metal residues in fish are analyzed. Finally, developmental and constructive suggestions for the current monitoring work are put forward, in order to provide reference for further research on heavy metal residues in fish.

Key words: heavy metal, fish, enrichment, research progress, accumulation characteristics, source apportionment
