But DuPont admits that the short-chain chemical GenX causes cancerous tumors in lab animals. A 2019 Auburn University study found that short-chains may pose even worse risks than long-chains, which supports scientists’ growing agreement that the entire class of PFAS are hazardous . Both PFOS and PFOA are the stable end products resulting from the degradation of precursor substances through a variety of abiotic and biotic transformation pathways (Conder and others 2010). Because of their chemical structure, PFCs, including PFOS and PFOA, are chemically and biologically stable in the environment and resist FRWA 2017 Focus on Change Presentation of Perfluorinated Chemicals/Perfluoriooctanoic Acid/Perfluorooctane Sulfonate 189 °C OU Chemical Safety Data (No longer updated) More details: 189 ° / 736 mm (190.4015 °C / 760 mmHg) Matrix Scientific: 189-192 °C Alfa Aesar L08862: 189 °C / 736 mm (190.4015 °C / 760 mmHg) Matrix Scientific 003771: 189 °C / 736 mmHg (190.4015 °C / 760 mmHg) SynQuest 21757, Perfluorooctane sulfonic acid (PFOS), as a potential endocrine disrupting chemical, is widely detected in the environment, wildlife and human.

Both PFOS and PFOA are very persistent in the environment. PFOS was widely used in the past in products to provide protective coatings to materials such as textiles and leather. It was also used in some fire fighting foams. However, most production of PFOS ceased in 2002.
