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.

Combining Freshwater Irrigation with Vegetable Selection to Mitigate the Occurrence of Per-and Polyfluoroalkyl Substances in Edible Vegetable Parts in a Semiarid Farmland in Northwestern China
Science
2 Jul 2024 | ACS ES&T Water
Reclaimed-water irrigation can introduce PFAS into farmlands, but switching to freshwater irrigation reduces PFAS levels in vegetables, with carrots and potatoes accumulating fewer contaminants than cabbage and pak choi, highlighting the importance of cleaner irrigation water for growing nonleafy vegetables.
