摘要 水产品是全球最为活跃的贸易产品之一，水产品的质量对经济发展至关重要。研究表明，膳食中鱼类的摄入是PFAS(per- and polyfluoroalkyl substances)经由水产品对人类的主要暴露途径。养殖水环境及水产品中的PFAS对水产品质量及人类健康构成不可忽视的直接威胁。本文综述了典型PFAS在养殖水体及水产养殖生物中的赋存状态、生物富集效应及生理毒性特征，探讨了其对养殖生物所产生的可能性作用机理，基于健康养殖与绿色安全水产品供应需求，梳理了功能性益生菌缓解PFAS对养殖鱼类的毒性效应及其内在作用机理，并针对目前研究中存在的问题，提出未来重点研究方向，包括水产养殖过程中PFAS污染物产生风险的客观评价、功能性菌株缓解PFAS污染物对养殖生物的毒性机理的研究及水产养殖过程绿色有效的PFAS污染物防控技术的研发等，以期为水产养殖过程中PFAS污染物的科学防控提供有益参考。
Abstract: Fish is one of the most actively traded products worldwide, and the quality of fish products is critical to economic development. Available studies have shown that dietary intake of fish is the main exposure pathway of per- and polyfluoroalkyl substances (PFAS) to humans via aquatic products. PFAS in aquaculture environment and aquatic products pose a direct threat to aquatic product quality and human health that cannot be ignored. In this paper, the state, bioenrichment effect and physiological toxicity of typical PFAS in aquaculture water and aquatic products are reviewed, the possible mechanisms of their effects on aquaculture organisms are explored, and functional probiotic strains to alleviate the toxic effects of PFAS are screened on aquaculture fish and their intrinsic mechanisms of action based on the demand for healthy aquaculture and green and safe aquatic products supply, and the problems in the current research are addressed. The risk of PFAS pollutants is objectively evaluated in aquaculture, the mechanism of functional strains to mitigate the toxicity of PFAS pollutants to cultured organisms, and the research and development of green and effective PFAS pollutant prevention and control technologies in aquaculture are proposed as the future key research directions, with a view to providing useful references to the scientific prevention and control of PFAS pollutants in aquaculture.
