海产食品微纳塑料污染现状与危害

近年来塑料对海洋环境的污染与日俱增。其中,微纳塑料碎片对海洋环境和动植物群落造成的危害,成为国际科学界的研究热点。许多商业上重要的海洋食材和食品,如甲壳类、双壳类、鱼类常常被微纳塑料污染,而微纳粒子表面通常吸附着有毒化学物质或者致病微生物,这些微纳粒子及有害物质可通过食物链富集于人体,对食品安全和人类健康构成了潜在威胁。本文主要对近年来海产品中微纳塑料污染状况及其危害的研究结果进行综述,为未来相关研究和食品安全管理提供借鉴。微纳塑料污染未来的研究重点应集中在3个方面,一是研究方法需创新并标准化,二是微纳塑料对人体健康的危害需进行全面深入的研究,三是加强微纳塑料危害食品安全的预防控制措施研究。

Situation and harm of micro-nano plastic pollution in seafood

In recent years, the pollution of plastics to the marine environment is increasing. Among them, the damage caused by micro-nano plastic fragments to the marine environment and animal and plant communities has become a research hotspot in the international scientific community. Many commercially important ingredients and marine foods, such as crustaceans, bivalves and fish, are often contaminated with micro-nano plastics, while micro-nano particles are often adsorbed with toxic chemicals or pathogenic microorganisms. These micro-nano particles and harmful substances can be enriched in the human body through the food chain, posing a potential threat to food safety and human health. This paper reviewed the research results of micro-nano plastic pollution and its hazards in marine products in recent years, and provided reference for future research and food safety management. The future research of micro-nano plastic pollution should focus on 3 aspects: first, the research methods needed to be innovative and standardized; second, micro-nano plastics needed to conduct comprehensive and in-depth research on human health hazards; third, strengthening research on prevention and control measures for micro-nano plastics to endanger food safety.
