PFAS in plant-biosolids-soil systems: Distribution, fractionation, and effects on soil microbial communities

This study examined the behavior of six U.S. Environmental Protection Agency (EPA) regulated per- and polyfluoroalkyl substances (PFAS) compounds in vegetated soils amended with Class A and Class B biosolids. Short-chain PFAS were evenly distributed throughout the 8-cm soil column, while long-cha…
