What are forever chemicals, and how do they impact our health? | BBC News

From BBC News.

BBC reporter Catrin Nye has been carrying out an investigation for BBC Panorama into how so-called forever chemicals could affect people’s health and contaminate the environment.

Forever chemicals, or PFAS (per-and poly fluoroalkyl substances), are a group of about 10,000 chemicals and are used in anything from cookware, to waterproof clothes, electronics and medical equipment.

They are persistent pollutants, meaning they don’t degrade easily and instead build up in the environment.

Scientists have linked a small number of them to serious harms, such as infertility and cancer.
