PFBSA

Perfluorobutanesulfonic acid, commonly known as PFBSA, is a synthetic chemical compound belonging to the per- and polyfluoroalkyl substances (PFAS) family. PFAS are a group of chemicals that are resistant to heat, water, and oil. PFBSA is characterized by a chain of four carbon atoms where all hydrogen atoms have been replaced by fluorine atoms, with a sulfonic acid functional group attached. This highly stable chemical structure contributes to its persistence in the environment and biological systems.

PFBSA has been used in various industrial and consumer applications due to its unique properties. These include its presence in some fire-fighting foams, surface coatings, and cleaning products. It is considered a shorter-chain PFAS compared to more widely studied compounds like PFOA and PFOS. However, like other PFAS, PFBSA is known for its environmental persistence, meaning it does not readily break down. It can also bioaccumulate in organisms.

Research into PFBSA's potential health effects is ongoing. Studies have suggested possible links to various health outcomes, although more definitive conclusions are still being investigated. Due to its persistence and potential for widespread distribution, PFBSA is a subject of concern for environmental scientists and public health officials. Monitoring and remediation efforts are being developed to address the presence of PFBSA and other PFAS in water sources and the environment.
