# PFAS: Camille Etienne publishes 'Factor X', legal action against Daikin > In late October 2026, the publication of Camille Etienne's investigative book 'Factor X', devoted to PFAS and the health consequences of the chemical industry, particularly around the Chemours plant, is announced and then presented as published. On October 27, an assessment indicates that, a year and a half after the law restricting PFAS, controls have intensified in France but that industrialists continue to discharge these persistent molecules into the environment. The same day, five associations challenge before the Lyon administrative court of appeal a prefectural order authorizing Daikin to replace a toxic PFAS with another in the Chemical Valley. **In brief**: Ongoing story bringing together 4 events nationwide, followed from 25 October 2026 to 31 October 2026. 11 articles from 9 sources (environment); last updated on 31 October 2026 at 10:00. - Status: ongoing - Category: Environment - Place: Nationwide - First detected: 25 October 2026 at 18:30 - Updated: 31 October 2026 at 10:00 - Web page: https://acturadar.com/en/stories/80-pfas-camille-etienne-publishes-factor-x-legal-action-against-daikin ## Coverage angles Left-wing media focus their articles on activist and associative mobilization (Camille Etienne's book, legal action against Daikin) and on health consequences, while center media concentrate on the legal procedure and the industrialist's response. **Common ground** - Five associations (or four NGOs and The Ecologists) challenge before the Lyon administrative court of appeal a prefectural order authorizing Daikin to use a new PFAS in the Chemical Valley - Camille Etienne's book 'Factor X' is published on October 29 by Les Arènes editions - A year and a half after the law restricting PFAS, controls have intensified but industrialists continue to discharge these molecules **Differences** - The left highlights the book's health and generational dimension and the presidential campaign, an angle absent from center articles - The center gives a voice to Daikin, which defends its project, an element absent from left-wing articles - The left presents the appeal as a request to ban a new pollutant, while the center describes it as a challenge to an order regulating operations ## Timeline (4 events) ### 25 October 2026 — [Parution d'un livre-enquête sur les PFAS et l'industrie chimique](https://acturadar.com/en/events/1208-parution-d-un-livre-enquete-sur-les-pfas-et-l-industrie-chimique.md) Le livre-enquête « Facteur X » de Camille Etienne, à paraître le 29 octobre, revient sur l'histoire de l'industrie chimique et ses conséquences sanitaires, notamment autour de l'usine Chemours. 1 sources, 1 articles · Nationwide ### 27 October 2026 — [Camille Etienne publie « Facteur X », enquête sur les produits chimiques](https://acturadar.com/en/events/1550-camille-etienne-publie-facteur-x-enquete-sur-les-produits-chimiques.md) La militante écologiste Camille Etienne publie un livre-enquête consacré aux effets des produits chimiques sur les organismes et l'environnement. 2 sources, 2 articles · Nationwide ### 27 October 2026 — [PFAS : où en est la France dans la lutte contre les polluants éternels ?](https://acturadar.com/en/events/2201-pfas-ou-en-est-la-france-dans-la-lutte-contre-les-polluants-eternels.md) Un an et demi après la loi restreignant les PFAS, les contrôles se sont intensifiés mais les industriels continuent de rejeter ces molécules persistantes dans l'environnement, selon un bilan. 1 sources, 1 articles · Nationwide ### 27 October 2026 — [PFAS: Associations' appeal against authorization of a new PFAS at Daikin near Lyon](https://acturadar.com/en/events/2397-pfas-associations-appeal-against-authorization-of-a-new-pfas-at-daikin-near-lyon.md) Five associations are contesting before the Lyon administrative court of appeal a prefectural order authorizing Daikin to replace a toxic PFAS with another in the Chemistry Valley. 6 sources, 7 articles · Vallée de la chimie, Lyon — Rhône --- Cite as: Acturadar, “PFAS: Camille Etienne publishes 'Factor X', legal action against Daikin”, https://acturadar.com/en/stories/80-pfas-camille-etienne-publishes-factor-x-legal-action-against-daikin Methodology: https://acturadar.com/en/methodology
