Field-testing polyethylene passive samplers for the detection of neutral polyfluorinated alkyl substances in air and water.

ABSTRACT: Fluorotelomer alcohols (FTOHs), perfluorooctane-sulfonamidoethanols (FOSEs), perfluorooctane-sulfonamides (FOSAs), and other poly- and perfluorinated alkyl substances (PFASs) are common and ubiquitous byproducts of industrial telomerization processes. They can degrade into various perfluorinated carboxylic acids, which are persistent organic contaminants of concern. We assessed the use of polyethylene (PE) passive samplers as a sampling tool for neutral PFAS precursors during field-deployments in air and water. A wide range of neutral PFASs was detected in polyethylene sheets exposed in wastewater treatment effluents in August 2017. Equilibration times for most neutral PFASs were on the order of 1 to 2 wk. Based on known sampling rates, the partitioning constants between polyethylene and w
