PFAS in northern gannet eggs from Canada’s St Lawrence Seaway basin fell, PFOS dropping from 100 ppb to 26 ppb by 2024.
The decline follows pressure from the United States, Europe, Canada, the United Nations, and 3M’s phase-out of PFOS and PFOA.
Scientists warn newer short-chain PFAS are increasing and harder to measure in bird eggs, keeping ecosystems contaminated.
