Fish, shellfish or seaweed? A Korean study found striking differences in chemical exposure
A national study of 4,279 Korean adults found that higher finfish consumption was associated with increased blood concentrations of PFAS, PCBs, and mercury, while shellfish showed narrower associations with three PFAS. Persistent chemical mixtures were also associated with modest increases in liver health biomarkers, and mediation analysis identified a positive PFAS-related pathway, although finfish intake was not significantly associated with GGT overall.
