As always, great reporting on the complexities of this issue. There's a lot of farmland that probably needs to be tested! www.nytimes.com/2024/12/06/c...

Excited to share the first real-time atmospheric measurements of #PFAS! We measured using acetate-CIMS in Toronto and see no evidence for direct emission of PFCAs. Rather, we see most are atmospherically formed. PFCA precursors must be considered and reduced! pubs.acs.org/doi/10.1021/...
