A Japanese-led study found bacteria in river sediment that can break down persistent organic pollutants, or "forever chemicals." The discovery offers a promising biological approach to cleaning up contaminated waterways, though further research is needed.
A new study shows that PFAS levels in northern gannet eggs in Canada have dropped by up to 74% over 55 years, reflecting the effectiveness of regulations controlling these chemicals. Scientists analyzed eggs from the St. Lawrence River basin and found that concentrations peaked in the late 1990s and early 2000s before declining sharply as regulatory pressure increased. The study authors say this demonstrates that regulations are working, though new PFAS compounds continue to pose risks.
