Concentration and human health risk attribute to per-and polyfluoroalkyl substances in fillet of carp and tilapia fish: systematic review and meta-analysis
Science
22 Aug 2024 | J. Food Compos. Anal.
The meta-analysis revealed that PFAS concentrations are highest in tilapia (193.45 µg/kg) and carp (47.17 µg/kg) from China, with the highest non-carcinogenic risk from PFAS consumption for adults also observed in China; risk levels in other countries are notably lower, though ongoing monitoring is needed.
