Dès que l’aménagement de la zone fut fini, DuPont commença à rejeter du PFOA, substance toxique utilisée dans la production du Téflon, dans la rivière Ohio. Le PTFE étant alors extrêmement coûteux, les faibles quantités commandées à DuPont étaient conservées dans le coffre-fort d'une banque[4]. When DuPont began transferring women workers out of Teflon, the company did send out a flier alerting them to the results of the 3M study. L'isolant en Téflon permet de supporter des températures de −90 à 260 °C[13]. “Neither clears away the legal hurdles that prevent the EPA from banning chemicals like asbestos, which we already know are dangerous.” Faber is also concerned that the reforms might interfere with regulatory laws introduced by states and other local governments to make up for the lack of effective federal oversight of chemicals. In 2011 and 2012, after seven years of research, the science panel found that C8 was “more likely than not” linked to ulcerative colitis — Wamsley’s condition — as well as to high cholesterol; pregnancy-induced hypertension; thyroid disease; testicular cancer; and kidney cancer. Ces produits pratiquement indestructibles s'accumulent dans le corps humain et dans l'environnement, créant une série de risques de santé publique particulièrement l'affaiblissement du système immunitaire, le dysfonctionnement du foie et les malformations congénitales[11]. DuPont elected not to disclose its findings to regulators. In one, drafted in 1989, after DuPont had bought local fields that contained wells it knew to be contaminated, the company spokesperson in the script winds up in an outright lie. Mais le revêtement antiadhésif est aujourd’hui dans le viseur des autorités sanitaires: un composant du revêtement miracle, marque déposée par la multinationale américaine DuPont, est soupçonné d’affecter gravement la santé humaine. The House and the Senate introduced separate TSCA reform bills this year and while the House passed its bill (HR 2576) in June, and the Senate was yet vote on its bill (S 697) as this story went to press. DuPont pourrait ainsi encourir des amendes totalisant 300 millions alors que la production des PFOA lui rapporte 100 millions par an. De plus, cette substance se dégrade très peu : elle a une demi-vie de 5,4 ans[15]. In 1954, the very year a French engineer first applied the slick coating to a frying pan, a DuPont employee named R. A. Dickison noted that he had received an inquiry regarding C8’s “possible toxicity.” In 1961, just seven years later, in-house researchers already had the short answer to Dickison’s question: C8 was indeed toxic and should be “handled with extreme care,” according to a report filed by plaintiffs. Because of its toxicity, C8 disposal presented a problem. Sometimes, between napping or watching baseball on TV, Wamsley’s mind drifts back to his DuPont days and he wonders not just about the dust that coated his old workplace but also about his bosses who offered their casual assurances about the chemical years ago. Il devrait être interdit d’ici 2015. Dupont doit faire appel et en passer par la Cour Suprême pour s’en sortir, même si parallèlement, il accepte des compromis avec des milliers de plaignants. En outre, le PFOA a été associé à une augmentation du taux de cholestérol et du nombre de cancers de la prostate en milieu professionnel. “I mean, it was [called] the Heckert-Eckhardt bill,” Steven D. Jellinek, the EPA’s first-ever assistant administrator for toxic substances, told the Chemical Heritage Foundation’s Oral History Project, referring to Richard Heckert, then a DuPont vice-president and the chair of the Manufacturing Chemists Association. In May 1984, DuPont convened a meeting of 10 of its corporate business managers at the company’s headquarters in Wilmington, Delaware, to tackle some of these questions. If the health effects on humans could still be debated in 1979, C8’s effects on animals continued to be apparent. Le revêtement miracle utilisé notamment dans la composition des poêles antiadhésives est accusé d’être dangereux. “I said, ‘I was in Teflon. Et comme c’est souvent le cas lorsqu’il y a des soupçons, des études sont réalisées un peu partout dans le monde et forcément…..elles sont contradictoires. That’s all it takes to support the journalism you rely on. Il accusa la société d’avoir contaminé plus de 70 000 personnes sur six districts différents. N’hésitez pas à choisir ce matériau pour vos cocottes par exemple. The settlement comes ahead of DuPont’s planned $130 billion merger with Dow Chemical, which is due to close later this year. Is this what happened to my baby?’” Bailey remembered. In some ways, C8 already is the tobacco of the chemical industry — a substance whose health effects were the subject of a decades-long corporate cover-up. C8 would prove to be arguably even more ethically and scientifically challenging for Haskell. DuPont employees knew in 1979 about a recent 3M study showing that some rhesus monkeys also died when exposed to C8, according to documents submitted by plaintiffs. Do Not Sell My Personal Information, Your California Privacy Rights Generation Forever War: Biden’s National Security Picks Herald Return to Hawkish Normalcy. L'évaluation scientifique lancée par l'EPA devrait permettre de savoir si la contamination des eaux et des sols par les PFOA a des impacts sur la santé humaine et l'environnement. In 1930, DuPont created Freon, making mass-market refrigerators and air conditioners possible for the first time. “Under the terms of the settlement, the company wasn’t even obliged to pull C8 from the market… the best the agency could negotiate was a voluntary phase-out by 2015,” the watchdog organization Environmental Working Group says in its May 2015 report “Poisoned Legacy.”. Do Not Sell My Personal Information. In October 2015, a jury awarded a kidney cancer patient $1.6 million after finding DuPont was liable for the leak. Like Wamsley, Sue Bailey, one of the plaintiffs whose personal injury suits are scheduled to come to trial in the fall, remembers having plenty of contact with C8. Malheureusement, les études indépendantes sur sa toxicité sont encore en cours et le principe de précaution n’est pas appliqué partout. Le Téflon fut donc d'abord appliqué par couches, comme de la peinture, avant que des modifications chimiques le rendent plus facilement utilisable[Lesquelles ?][4]. Une étude danoise de 2009 a même montré une corrélation entre taux de PFOA dans le sang et la stérilité masculine. But in 1980, when she was in the first trimester of her pregnancy with Bucky, she moved to Teflon, where she often sat watch over a large pipe that periodically filled up with liquid, which she had to pump to a pond in back of the plant. It was a problem”. Concerns about the hazards posed by Teflon and C8 began to garner public attention only about 15 years ago. The next year, an in-house DuPont attorney named Bernard Reilly helped open an internal workshop on C8 by giving “a short summary of the right things to document and not to document.” But Reilly — whose own emails about C8 would later fuel the legal battle that eventually included thousands of people, including Ken Wamsley and Sue Bailey — didn’t heed his own advice. Depuis des années les plaintes fusent sans résultats. As the meeting summary noted, “We are already liable for the past 32 years of operation.”. Il appliquait un revêtement de Téflon à ses moules pour que les mandrins se défassent plus facilement. October 10, 2020 [12] Electron beam processing is one example of radiation processing.
