A team of researchers at the U.S. Environmental Protection Agency (EPA), working with colleagues from the Institute of Environmental Engineering, ETH and North Carolina State University has conducted a review of the research done on per- and polyfluoroalkyl substance (PFAS)-containing products and has found that very little is known about their impact on either the environment or human health. They have published a Review piece in the journal Science outlining their work, their findings and what they believe needs to happen regarding the use of the chemicals in products moving forward.
