Perfluoroalkyl acids (#PFAAs) are widely distributed in the #oceans which are their largest global reservoir, but knowledge is limited about their vertical distribution and fate. This study measured the concentrations of PFAAs (#perfluoroalkyl carboxylic acids (PFCAs) with 6 to 11 carbons and perfluoroalkanesulfonic acids (PFSAs) with 6 and 8 carbons) in the surface and deep ocean. #pollution #PFAS https://pubs.acs.org/doi/10.1021/acs.estlett.3c00119
