www.epa.govMore recently, industry has developed and adopted alternative short-chain PFAS chemistries to replace long-chain PFAS. Many short-chain PFAS are structurally similar to their long-chain predecessors being replaced and are manufactured by the same companies. Publicly available health, toxicity, and hazard assessments of short-chain PFAS are limited.

nasf.orgHistorically, the metal plating industry has used, and continues to use, per- and polyfluoroalkyl substances (PFAS) in some metal plating applications. Most notably, beginning in the 1980s, perfluorooctanesulfonic acid (PFOS) was used as a mist suppressant in hard and decorative chromium ... the formation of the short -chain perfluorocarboxylic ...

ec.europa.euShorter chain PFAS have been developed more recently to substitute the longer chain ones. In this context, an important distinction is the one between “long chain” and “short chain” PFAS6. The PFAS group includes also polymers: e.g. fluoropolymers7, perfluoropolyethers8 and side-chain fluorinated polymers9.
