Researchers have long associated per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," with certain severe birth defects, but exactly how these pollutants harm a developing fetus has remained mostly a mystery. New research now provides the first clear molecular explanation, showing how one PFAS, called perfluorodecanoic acid (PFDA), can trigger craniofacial abnormalities before birth. The research was published today in Chemical Research in Toxicology.
