解锁磷氟资源开发与生态保护双赢路径

Core Viewpoint - The research highlights the critical environmental and health risks associated with PFAS (per- and polyfluoroalkyl substances) in marine ecosystems, particularly in edible fish, emphasizing the need for effective management and regulation of these substances in the context of global fisheries and trade [1][2][3] Group 1: Research Findings - The study assessed PFAS concentrations in 212 species of edible fish globally, revealing that PFAS levels are closely linked to historical emissions and the dilution capacity of seawater [2] - A predictive model based on 20 years of seawater monitoring data was validated, showing that 33% of data errors were within twofold and 94% within tenfold of actual measurements [2] - The research indicates that PFAS pollutants are being transferred from high-pollution areas to low-pollution areas through global fish trade, posing significant health risks [2] Group 2: Methodology and Framework - An innovative assessment framework was developed, linking environmental concentration, food web accumulation, trade flow, and health risk, providing essential scientific evidence for fisheries management and PFAS regulation [3] - The study was a collaborative effort involving multiple institutions, supported by significant funding from national and local science foundations [3] Group 3: Institutional Impact - The research represents a significant breakthrough for the laboratory, aligning with national strategic needs and focusing on the lifecycle of strategic resources like phosphorus and fluorine [3] - The university has made notable progress in producing original research outcomes, contributing to the national "Double First-Class" initiative [3]
