Perfluorooctanesulfonic acid (PFOS)

ingredientContaminantsAlso known as: PFOS

Summary

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.

What it is

PFOS is a fully fluorinated anionic surfactant, known for its stability and persistence in the environment.

Common uses

  • Fire-fighting foam

  • Textile coatings

  • Paper packaging

  • Metal plating

Public Perception

Anxiety level

High, due to its persistence and potential bioaccumulation.

Source sentiment

Concerned due to potential environmental and health risks.

History

Timeline

2000

3M, a major producer, announced the phase-out of PFOS production.

2009

PFOS was added to the Stockholm Convention on Persistent Organic Pollutants.

Origin

Surfactant and protective coating

First appeared: 1949

Science

Key findings

  • 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.

Safety status

Considered hazardous due to environmental persistence and potential health effects.

Nuance

The extent and severity of health effects from PFOS exposure are still being studied.

Alternatives

Short-chain PFAS

Some short-chain PFAS compounds are being used as replacements, though their safety is also under investigation.

Avoidance tips

  • Check product labels for PFAS or perfluoro compounds.

  • Support companies committed to phasing out PFAS.

  • Use water filters certified to remove PFAS.
