PFAS News and Resources

Welcome to CL:AIRE's PFAS webpage - a compilation of information relevant to the understanding and management of per- and polyfluoroalkyl substances (PFAS).

PFAS are a broad group of synthetic fluorinated chemicals widely applied for bulk industrial uses and in consumer applications since the 1930s. It has been estimated that the PFAS family may include many thousand chemical substances. Due to their persistence in the environment and link to various health issues, PFAS are the subject of environmental concern globally.

On this page you will find PFAS resources and publications sorted by publisher, and PFAS news sorted by the date the article was published on CL:AIRE's website. The material has been sourced from across the world and we would like your help to keep the site up to date. If you have additional documents or news that should be included on this page please let us know via the Helpdesk, noting we are not looking for commercial publications.
