Key Points

The study detects per- and poly-fluoroalkyl substances in marine mammals' brains, indicating environmental contamination.
Brain samples from species such as harbor seal and porpoise revealed varying levels of PFAS, signifying ecological risks.
Observational analysis of brain samples from several marine mammal species, focusing on environmental health impacts.
Findings may highlight the need for monitoring PFAS in marine ecosystems to protect wildlife health.

Implication

This study measures PFAS levels in brain samples of marine mammals, highlighting potential risks in wildlife.

Abstract

This study focused on measuring 80 target per- and poly-fluoroalkyl substances (PFAS) in brain samples from various marine mammals, including: harbor seal, gray seal, harp seal, hooded seal, harbor porpoise,...
