Teflon's scientific name is ammonium perfluorooctanoate, which was invented by DuPont in the United States half a century ago. It is an artificially manufactured fluorinated polymeric acid and is currently a must-have material for the production of nonstick coating. This material is highly stable, difficult to degrade in the environment, has anti-oxidation, anti-adhesion, rust-proof function, has been widely used in non-stick pans and other household kitchen utensils, steel anti-rust coating and other products for many years. However, in recent years, the scientific community has discovered that Teflon pollutes the environment and may also cause potential harm to the human body. According to research conducted by various agencies such as the US Environmental Protection Agency and the National Institutes of Health, Teflon pollutes water and air. Today, most Americans have traces of Teflon in their blood, and 95% of U.S. residents can detect their blood in the blood. This substance. Teflon can also accumulate in the fetus through the blood, and even found in wild polar bears. Although the effects of trace Teflon on the human body are not yet clear, in animal experiments, high-dose Teflon has been shown to induce liver cancer, suppress the immune system, cause fetal weight loss and developmental malformations.
In addition to DuPont, the largest production company of Teflon, and the US Environmental Protection Agency, there are chemical companies such as Swiss Ciba and Japan Daikin. These companies promised to reduce Teflon’s production and emissions by 95% in 2000 over the next four years. By 2015, the company will stop production globally and cease to emit Teflon. In addition, these companies also promised to disclose to the public the research results on the pollution mechanism and toxic and side effects of Teflon. Previously, DuPont was accused of concealing the side effects of Teflon for 20 years and concealed the fact that Teflon was polluting the Ohio River Valley. It was fined by the US Environmental Protection Agency for a massive fine of US$16.5 million. This is the The EPA has imposed the heaviest administrative fines in history. DuPont was also forced to pay more than 100 million US dollars to compensate local residents.
According to the “Scientific Times†report on February 7, 2006, the US Environmental Protection Agency recently reached an agreement with eight major chemical companies such as DuPont to stop production of Teflon, a chemical material that causes pollution, by 2015. This is the first time the United States has The controversial Teflon product took full action.
