Annual production increased from about 30 tons in 2003 to 60 tons in 2013.[1]
Environmental issues
editIt is predominantly biotransformed to perfluorooctanesulfonic acid (PFOS),[2] but partly also to perfluorooctanoic acid (PFOA).[3][4] Sulfluramid benefits from an acceptable purpose in the listing of PFOS to annex B of the Stockholm Convention on Persistent Organic Pollutants.
