New PFAS Additions to the Proposition 65 List
Over the past week, several new per- and polyfluoroalkyl substances (PFAS) have been added to California’s Proposition 65 list. In March 2021, California’s Office of Environmental Health Hazard Assessment (OEHHA) selected perfluorooctane sulfonate (PFOS) and its salt and transformation and degradation precursors for evaluation by California’s Carcinogenic Identification Committee (CIC). OEHHA also selected perfluoronanoic acid (PFNA) and… Continue reading
