UK MPs are calling for a ban on PFAS, a class of chemicals known as "forever chemicals" because they persist in the environment and human bodies. The chemicals should be phased out of everyday products including school uniforms, non-stick cookware, and food packaging, lawmakers say.
PFAS are fluorinated compounds used to repel water, grease, and stains. They accumulate in the body over time and have been linked to health concerns including liver damage, immune system suppression, and thyroid disease. Because they break down extremely slowly in the environment, PFAS contaminate drinking water supplies and soil across much of the developed world.
The chemicals are particularly common in non-stick frying pans, where they coat cooking surfaces. They also appear in water-resistant school uniforms and fast-food packaging designed to prevent grease seepage. The widespread use means exposure is nearly unavoidable for most people.
MPs argue that safer alternatives exist for most applications. The push for a ban reflects growing international pressure on manufacturers. Several countries and the European Union have begun restricting PFAS use, particularly in certain product categories. Environmental and health advocates have intensified campaigns against the chemicals as scientific evidence of their persistence and bioaccumulation mounts.
