Response: Per- and polyfluoroalkyl substances (PFAS) are a class of artificially synthesized chemicals widely used in industrial production and consumer goods manufacturing. These substances are persistent in the environment, can accumulate through the food chain, and enter the human body and build up over time, posing a potential threat to health. As an important component of the global diet, marine fish may serve as a major source of PFAS intake for humans. However, the contribution of marine fish as a source of PFAS exposure and the associated health risks still lack systematic assessment on a global scale.
