Perfluorobutane sulfonamide

Perfluorobutane sulfonamide, also known as FBSA or H-FBSA, is a perfluorinated surfactant. FBSA and its N-alkylated derivatives have been patented by 3M for use in acid etch solutions with low surface tension. According to the inventors, FBSA and its derivatives are expected to have a smaller tendency to accumulate in living organisms than their perfluorooctanyl analogs such as PFOS.[1] Nevertheless, a 2015 study found FBSA in 32 out of 33 samples of Canadian fish.[2]

In April 2019, 3M admitted in a letter to the EPA that the plant in Decatur, Alabama released FBSA and FBSEE into the Tennessee River, despite a 2009 EPA order prohibiting release to water.[3] Supposedly, authorities had been aware of the contamination since 2014, but did not make it public.[4] The same facility has been responsible for release of other per- and polyfluorinated alkylated substances, namely PFOS and PFOA, into the Tennessee River, prompting 3M to pay $35 million to a local water authority in order to improve drinking water purification.[5]
