How PFAS regulation cut toxic chemical levels in Canadian wildlife
BY THE OPTIMIST DAILY EDITORIAL TEAM Levels of some of the most toxic PFAS compounds have fallen sharply in Canadian seabird eggs, and the reason isn’t complicated. Regulation worked. A peer-reviewed study tracked PFAS concentrations in the eggs of northern gannets on Bonaventure Island, in the St. Lawrence Seaway basin, over 55 years. PFOS, one of the most common and toxic PFAS compounds, peaked at 100 parts per billion in the eggs, then dropped to 26 parts per billion by 2024, a 74 percent dec
