You have probably heard a lot about per- and polyfluoroalkyl substances (PFAS) in the news and among scientific communities, especially in the last few years. PFAS are a large group of compounds that have been used widely to make everyday products resistant to stains, grease, and water. They are also a component of aqueous film-forming foams, which have been used for fire suppression at airports, industrial facilities, and military sites. PFAS contain carbon-fluorine bonds, which are among the strongest known in chemistry. Unfortunately, the chemical properties that make PFAS stable and desirable for so many applications and products also make them incredibly persistent in the environment.

Superfund Research Program (SRP)-funded scientists and engineers are using innovative approaches to understand the health effects of per- and polyfluoroalkyl substances (PFAS), a large group of compounds found in aqueous film-forming foams, which have been used for fire suppression at airports, industrial facilities, and military sites, and in everyday products. They also are exploring how PFAS move and change in the environment and how to clean them up to better protect human health.
SRP grantees from all over the country gathered in Baltimore, Maryland, for the 2019 Society of Toxicology (SOT) Annual Meeting on March 10 - 14. More than 70 SRP project leaders and trainees from at least 15 SRP Centers presented oral and poster presentations.

New research out of the University of Iowa SRP Center identified specific cytochrome P450 (CYP) enzymes and underlying mechanisms involved in the breakdown, or metabolism, of polychlorinated biphenyls (PCBs) into compounds that may be more toxic.
SRP-funded small business CycloPure, Inc., has developed a new product, DEXSORB+, which works to rapidly remove per- and polyfluoroalkyl substances (PFAS) from contaminated water supplies. CycloPure recently announced that in addition to SRP funding, they have raised an additional $3.5 million to accelerate the commercialization of their DEXSORB products. This will help them to make the technology available to consumers and municipal drinking water plants impacted by PFAS and other contaminants.
