Definition of perfluorooctanesulfonic acid:
Perfluorooctanesulfonic acid (PFOS) is a man-made global pollutant. PFOS is suspected of compromising the immune system of wildlife and a small segment of highly exposed people globally.[1]
This is the common definition for perfluorooctanesulfonic acid, other definitions can be discussed in the article

Notes

PFOS is a persistent compound, shows little biodegradation and are globally distributed in living organisms. They are found in almost all animals, in almost all environments, including the arctic. Although they also have a high tendency to bioaccumulate, they seem to behave differently from organoclorine compounds, for PFOS no clear relationship of accumulation with age, could be determined. Uncertainty about the exact environmental fate. Cite error: Invalid <ref> tag; invalid names, e.g. too many [2]
