Per- and Polyfluoroalkyl Substances (PFAS) in the U.S.
A recent study published in Science of The Total Environment examines the pervasive issue of per- and polyfluoroalkyl substances (PFAS), synthetic chemicals dubbed “forever chemicals” due to their persistent nature in the environment and human body. Widely used since the 1940s in products like nonstick cookware, water-repellent fabrics, firefighting foam, and food packaging, PFAS are valued for their resistance to heat, water, and oil. However, their strong carbon-fluorine bonds make them resistant to degradation, leading to widespread contamination in water, soil, wildlife, and humans globally. The study highlights significant health concerns tied to PFAS exposure, which occurs through contaminated water, food, dust, and consumer products. Research has linked certain PFAS, notably PFOA and PFOS, to an elevated risk of kidney and testicular cancers, with emerging evidence suggesting connections to breast, ovarian, and prostate cancers. These chemicals accumulate in the body,…
