Story summary

Researchers from the University of California, Davis, and State University of New York at Buffalo find that over 90% of Magellanic penguins along Argentina's Patagonian coast carry PFAS signals.
PFAS are synthetic substances used for water- and grease-resistance and can take more than 1,000 years to degrade.
The study, published in Earth: Environmental Sustainability, notes that newer PFAS marketed as safer still pose risks to wildlife and motivates expanding monitoring.
