Per- and polyfluoroalkyl substances (PFAS) – synthetic “forever chemicals” – have become a substantial and pervasive global challenge. They have managed to infiltrate diverse ecosystems, contaminate water sources, and accumulate in human bodies. They are incredibly persistent and have significant adverse effects on both human health and the environment. Acting now to unravel the complexity of the PFAS problem and implement effective solutions is critical to prevent further accumulation in the environment and secure a healthier future for generations to come. Part two of our PFAS blog series will address the health risks associated with PFAS and the EU’s recently proposed restriction.
