Lithium ion batteries a growing source of PFAS pollution, study finds

A study by Texas Tech University reveals that lithium-ion batteries are contributing to per- and polyfluoroalkyl (PFAS) pollution in air and water through the use of a new subclass of PFAS called bis-perfluoroalkyl sulfonimides (bis-FASIs). These compounds show environmental persistence and ecotoxicity similar to older PFAS like perfluorooctanoic acid (PFOA). The research, published in Nature Communications, highlights the high levels of bis-FASIs near manufacturing plants and their potential long-range transport through air emissions. Toxicity testing on aquatic organisms indicates behavioral changes and metabolic impacts. However, treatment methods like granular activated carbon and ion exchange can reduce bis-FASI concentrations in water. The study emphasizes the need for clean energy technologies to address carbon emissions while minimizing environmental pollution. Researchers stress the importance of interdisciplinary collaboration to develop sustainable energy solutions and minimize environmental impacts. The findings underscore the importance of balancing clean energy initiatives with environmental protection measures to combat the climate crisis effectively.
