Propanedioic acid, mono(γ-ω-perfluoro-C8-12-alkyl) derivs., di-me esters

Industrial production and use of water‑/oil‑repellent coatings for textiles, paper, leather, and other products; releases from treated items and waste handling sites [1][2].

Drinking contaminated water, indoor dust from stain‑treated carpets and furniture, some food packaging, and certain workplaces (manufacturing, metal plating, firefighting foams) [1][2].

PFAS persist and can accumulate; exposure is linked to higher cholesterol, immune effects (lower vaccine response), liver and thyroid changes, and developmental/pregnancy effects; some PFAS (e.g., PFOA) cause cancer [2][3][4].

People using private wells near industrial sites or firefighting areas, workers handling PFAS, pregnant people, and infants (especially if formula is mixed with contaminated water) [1][2].

Test private wells for PFAS; consider certified filters (reverse osmosis or activated carbon certified for PFAS). Limit stain‑resistant treatments, clean dust with HEPA/ wet methods, and follow workplace protections [1][2][5].
