Per/polyfluoroalkyl Substances (PFASs)

Figure.1 (The chemical structure of representative PFASs; PFOS, PFOA)*

PFASs are generally known as a persistent substance which it is hard to decompose/metabolise in our body. These chemicals are used especially in non-sticking pan, fire extinguisher/firefighting foam, water/oil repellant fabric sprays, carpets, lubricants… which we can find at any place. When such things are being consumed nor inhaled, these chemicals will gradually form abnormalities inside our body causing serious problems such as cancer located in; thyroid; bone; liver; kidney, infertility, growth problem, hormonal problems, learning disabilities immunological problems.

The limit (NOAEL; No-observed-adverse-effect level) differs from person to person, but knowing what we are using will makes you stay healthy without intaking carcinogens.

* Not only two substances but also there are around 50 subtypes of PFASs that can be detected.
