Summary

A spatially resolved multimedia investigation of the fluoropolymer production facility at Spinetta Marengo, Italy, traced both legacy and emerging PFAS from emission sources through air, water, and soil to surrounding ecosystems. The study is significant for understanding how industrial plastic manufacturing creates long-range, persistent chemical contamination that complements the physical microplastic burden in affected environments.

Perfluoropolymer manufacturing is a major source of non-polymeric PFAS to the ecosystems. The environmental release, transport, and fate of both legacy and emerging PFAS emitted by the fluoropolymer plant in Spinetta Marengo (Northern Italy), one of the main fluoropolymer production facilities in Europe, have been investigated by using a systematic and spatially resolved multimedia approach.
