Perfluorooctanesulfonic acid (PFOS) is a synthetic perfluorinated compound that has been used in a variety of industrial and consumer applications due to its surfactant properties.
PFOS is a fully fluorinated anionic surfactant, known for its stability and persistence in the environment.
Fire-fighting foam
Textile coatings
Paper packaging
Metal plating
High, due to its persistence and potential bioaccumulation.
Concerned due to potential environmental and health risks.
3M, a major producer, announced the phase-out of PFOS production.
PFOS was added to the Stockholm Convention on Persistent Organic Pollutants.
Surfactant and protective coating
First appeared: 1949
PFOS is highly persistent in the environment.
PFOS can bioaccumulate in living organisms.
Exposure to PFOS has been linked to potential health effects in humans and animals.
Considered hazardous due to environmental persistence and potential health effects.
The extent and severity of health effects from PFOS exposure are still being studied.
Short-chain PFAS
Some short-chain PFAS compounds are being used as replacements, though their safety is also under investigation.
Check product labels for PFAS or perfluoro compounds.
Support companies committed to phasing out PFAS.
Use water filters certified to remove PFAS.
