Previous focus on legacy substances may have severely underestimated overall exposure of breastfed infants to PFASs
Scientists have analysed breast milk from women living in cities in China and Sweden to check for 20 per- and polyfluoroalkyl substances (PFASs). The study detected significant levels of legacy PFASs and alternatives to those older PFASs, and is one of the first studies to detect 9-chlorohexadecafluoro-3-oxanone-1-sulfonic acid (F53-B) and 3H-Perfluoro-3-[(3-methoxy-propoxy)propanoic acid] (ADONA) in human breast milk.
