PFAS

Also called Forever chemicals, Per- and polyfluoroalkyl substances

PFAS are long-lasting synthetic chemicals used in water-resistant fabrics, some food packaging and non-stick products.

Many PFAS break down slowly and can build up in water, food and human blood. Regulators have restricted legacy compounds such as PFOS and PFOA, but environmental levels remain measurable. Major health agencies say more research is needed to tie specific blood levels to individual outcomes.
