Occitanie (France) — Ambient Air: A First‑of‑Its‑Kind Study Measuring Pesticides, Endocrine Disruptors and PFAS Simultaneously 🌬️🧪

Understanding what we breathe daily is essential for effective public policy.
For the National Air Quality Day, Atmo Occitanie published an unprecedented snapshot of combined exposures in the region: pesticides, potential endocrine disruptors and PFAS measured simultaneously across Occitanie.

📌 What Atmo Occitanie Published (10/10/2025)

✦ Monitoring of pesticides across 10 sites, including the metropolitan areas of Toulouse and Montpellier.
✦ Expanded monitoring on 5 of the 10 sites, adding measurements of potential endocrine disruptors and PFAS:
• Metropolitan environments: Toulouse, Montpellier
• Rural environments: Aude Viticole, Haute‑Garonne Grandes‑Cultures
• Industrial basin: Gard Urbain
✦ 192 molecules investigated.
✦ Objective: better characterise multi‑exposure, document spatio‑temporal variations and seasonality.
✦ Results available through La Lettre de l’Air and AtmoViz.
✦ Part of a long‑term monitoring strategy.

🔎 A Milestone for Local Action

✦ PFAS are not just a water issue: their presence in air also matters due to deposition and inhalation exposure pathways.
✦ Comparable data across sites and over time helps local authorities prioritise action, whether through agricultural practices, planning decisions or public information.

“Everyone has the right to air that does not harm their health,” notes Emilie Dalix, President of Atmo Occitanie.
