Q&A: EPA finalizes phase-out plan for 'forever chemicals' known as PFAS
Long-term, low-dose exposure to per- and polyfluoroalkyl substances, also known as PFAS or forever chemicals, can hinder the immune system, interfere with hormones, and reduce the effectiveness of vaccines. It can also cause low birth weight and high cholesterol. High doses of PFAS increase the risk of kidney cancer, liver damage, testicular cancer, and thyroid disease.
