Perfluorooctane sulfonate or perfluorooctanyl sulfonate (PFOS) is a synthetic (human made) chemical belonging to a large family of compounds known as perfluorinated chemicals. The exposure of some wildlife organisms in Canada (e.g., polar bear, bird species) to PFOS could be near or at levels that are harmful to them.

Groundwater that is affected by PFOA or PFOS is often polluted by soil and air contamination. Surface water can be affected when the chemicals used in manufacturing facilities enter directly into a water source.

3M, the primary manufacturer of PFOS, began a voluntary phase-out of the chemical in 2000. This came as a result of a series of studies showing significant PFOS accumulation in the environment. In 2006, under the guidance of the EPA, eight major companies followed suit and began removing PFOS, PFOA, and other related compounds in the PFAS category.

Trattasi di un acido molto forte, che per ionizzazione forma l'anione perfluoroottansolfonato, noto con la sigla PFOS.Questi composti hanno proprietà tensioattive e sono inquinanti organici persistenti.Il PFOS era l'ingrediente chiave di vari prodotti antimacchia e idrorepellenti per tessuti, tra i quali PFOS stands for perfluorooctanesulfonic acid or perfluorooctane sulfonate.

Groundwater that is affected by PFOA or PFOS is often polluted by soil and air contamination. Surface water can be affected when the chemicals used in manufacturing facilities enter directly into a water source. PFAS are a large, complex, and ever-expanding group of manufactured chemicals that are widely used to make various types of everyday products. For example, they keep food from sticking to cookware, make clothes and carpets resistant to stains, and create firefighting foam that is more effective.

PFOS has adverse effects on hepato-histology and sexual development on X. laevis. PFOS can induce oxidative stress-mediated DNA damage repair systems with transcriptional regulation of detoxification, antioxidant, and apoptosis-related genes, resulting in developmental retardation and reduced fecundity in the copepod T. japonicus.
