Perfluorooctanesulfonic acid (PFOS) is a synthetic perfluoroalkyl substance characterized by a long carbon chain with a sulfonic acid functional group. It is a colorless, odorless, and highly stable compound, known for its exceptional resistance to heat, water, and oil, which makes it useful in various industrial applications, including firefighting foams, stain-resistant coatings, and surfactants. PFOS is highly soluble in water and has a strong tendency to bioaccumulate in living organisms due to its persistence in the environment. Its chemical stability and resistance to degradation raise concerns regarding its environmental impact and potential health risks, leading to regulatory scrutiny and restrictions in many countries. PFOS has been associated with adverse health effects, including developmental and reproductive toxicity, prompting efforts to phase out its use in favor of safer alternatives. Overall, while PFOS has useful properties, its environmental persistence and potential health risks have made it a subject of significant regulatory attention.
