The hottest DuPont will face the highest environme

  • Detail

DuPont will face the highest environmental penalty in U.S. history on July 15, 2004, the U.S. Environmental Protection Agency said that DuPont had not reported a key raw material for Teflon manufacturing for 20 years that might bring potential harm to human health. Therefore, the Environmental Protection Agency decided to impose a huge fine of hundreds of millions of dollars on DuPont, This may become the largest environmental penalty in American history

the so-called Teflon (photoelectric induction is the relatively advanced technology Teflon) is the general name of all hydrocarbon resins developed by DuPont (commonly known as "TEFLON" registered by DuPont in the market), including polytetrafluoroethylene and perfluoroethylene. It has won one first prize, three second prizes and one third prize of China nonferrous metal industry science and technology progress award. Because of its unique excellent heat resistance (180 ℃ -260 ℃), low temperature resistance (-200 ℃), self lubrication and chemical stability, it is known as "Teflon that resists corrosion and never sticks". The US Environmental Protection Agency pointed out that DuPont had never reported that perfluorooctanoic acid (C-8), the main ingredient in the manufacturing process of Teflon, might be harmful to human body from june1981 to March2001, and had violated the poison control law. Perfluorooctanoic acid is a substance similar to soap, which can be used to make anti fouling surfaces and various consumer goods, including non sticky pots, anti fouling carpets, Goretex polyethylene fabrics, etc. However, according to the research of 3M company in the United States, the original manufacturer of perfluorooctanoic acid, a large amount of exposure to perfluorooctanoic acid may cause cancer or affect the reproductive function of mice. 3M company has stopped producing antifouling products with similar ingredients since 2000

the main drafters of this standard by the US Environmental Protection Agency: jiangbingnian, kangjianhua, baojunhai, gongjunfan and yangshiye show that as early as the early 1980s, DuPont had found perfluorooctanoic acid residues in a pregnant female worker in a West Virginia factory. In 1991, it found perfluorooctanoic acid residues in water sources in communities near the state and Ohio that exceeded the safety standards set by the company, However, they have not informed the environmental protection agency that perfluorooctanoic acid may cause significant harm to human body or the environment. According to the test of the environmental protection agency, perfluorooctanoic acid can remain in the human body for up to four years. On October 23, the environmental protection agency also found a small amount of perfluorooctanoic acid residues in many ordinary Americans

the US Environmental Protection Agency decided to take action against DuPont after being jointly pressured by the "environmental protection working group" of non-governmental environmental protection organizations and residents of Ohio and West Virginia who are suing DuPont. Residents in Russia and Western Virginia have accused DuPont of polluting the soil and drinking water near the paxsburg plant in western Virginia. Local community residents suffer from respiratory diseases and cancer, which may be related to the perfluorooctanoic acid discharged by DuPont

Skinner, head of the Executive Office of the environmental protection agency, said that the agency may impose heavy fines of hundreds of millions of dollars on DuPont, of which the daily fine for violating the law before January 30, 1997 was 25000 dollars, and then the daily fine was increased to 27500 dollars. It is roughly estimated that the total fine will reach about 300million dollars
