Environmental analysis reveals novel hydrogen-substituted polyfluoroalkyl ether sulfonates in industrial waterways, indicating unmonitored degradation pathways of industrial fluorosurfactants.

Key Points

To evaluate the reductive transformation behavior of the fluorosurfactant Cl-6:2 PFESA and determine whether novel hydrogen-substituted breakdown products occur in industrial aquatic environments.
Investigated reductive dehalogenation kinetics of Cl-6:2 PFESA in an anaerobic super-reduced cyanocobalamin assay paired with a nontarget screening workflow.
Quantified target transformation products using laboratory-purified standards in river water and sediment samples collected from two distinct regions near metal-plating facilities.
Anaerobic reductive dehalogenation rapidly transformed Cl-6:2 PFESA into 1H-6:2 PFESA as the dominant breakdown product.
Field monitoring detected geometric mean concentrations of 560 pg/L in river water and 11.1 pg/g in sediment for 1H-6:2 PFESA, and 11.0 pg/L in river water and 7.69 pg/g in sediment for 1H-8:2 PFESA.
1H-6:2 and 1H-8:2 PFESA comprised average compositions of 1% and 0.1%, respectively, among the 18 monitored per- and polyfluoroalkyl sulfonate and carboxylate contaminants.
