水产品中新污染物风险评估研究进展OA

Emerging pollutants pose significant threats to ecosystems and human health because of their persistence,bioaccumulation,and potential toxicity,and have become a global research priority and regulatory concern.This re-view systematically summarizes current research on emerging pollutants in aquatic products,including their defini-tions,main categories,sources,occurrence,distribution and bioaccumulation characteristics.The review finds that emerging pollutants are enriched along the food chain and exhibit pronounced species,tissue-,and region-specific differences in concentrations,leading to multiple adverse effects such as endocrine disruption and neurodevelopmental toxicity.In addition,certain pollutants,including per-and polyfluoroalkyl substances and short-chain chlorinated paraffins,present potential risks to ecological safety and human health in some regions.Building on these findings,this review identifies three major challenges in current risk assessment:the lack of models for combined exposure,in-sufficient data on chronic low-dose toxicity,and the absence of robust toxicological benchmarks and regulatory stand-ards.Accordingly,this review further examines future research directions for risk assessment of emerging pollutants in aquatic products and proposes corresponding risk management strategies to support more effective identification and control of emerging pollutant risks in aquatic food systems.
