Concentration profiles of per- and polyfluoroalkyl substances in major sources to the environment

A review of published literature was conducted to present the concentrations and composition profiles of per- and polyfluoroalkyl substances (PFAS) from significant sources to the environment. The characteristic compounds and concentrations are summarized as found from direct sources such as manufacturing facilities, aqueous film-forming foam (AFFF) applications, metal coating operations, and textile and paper coating operations; and from indirect sources such as landfills and wastewater treatment plants (WWTPs).

Information Requirements under the Essential-Use Concept: PFAS Case Studies

This study investigates how much information is available on the types and functions of PFAS in these uses, how much information is available on alternatives to the use of PFAS in various products, their performance and hazardous properties and, finally, whether this information is sufficient as a basis for deciding on the essentiality of a PFAS use.
