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 organochlorine compounds, for PFOS no clear relationship of accumulation with age, could be determined. Uncertainty about the exact environmental fate. [2] [3]


It can also influence the lipid metabolism (in rodents), and reduces weight gain and food consumption. This leads to abortions and reduced fetal weight. Further it can induce liver necrosis.
