in its recently published environmental science and technology, the American Chemical Society, the world's largest science and Technology Association, pointed out that in the blood of nearly 500 respondents around the world, substances suspected to be carcinogens by the US Environmental Protection Agency were found The processing aid of Teflon coating -- the residue of perfluorinated compounds. The Research Report of the US Environmental Working Group shows that ammonium perfluorooctanoate (PFOA) is harmful to animals. At a time when consumers are disturbed by the DuPont non stick pot incident, the news is like a heavy bomb

perfluorinates proved harmful

the Journal of environmental science and technology of the United States revealed that since last year, the American Chemical Society has organized experts and scholars to conduct blood tests on 473 volunteers from the United States, Colombia, Brazil, Belgium, Italy, Poland, India, Malaysia and South Korea. The results showed that all of these volunteers' blood contained the residue of perfluorooctanoic acid (PFOA)

the US Environmental Working Group claims that the latest animal experiments have shown that PFOA is harmful to animals. After eating food containing PFOA, the growth and development of mice are obviously slow, and the nervous system, immune system and reproductive system are also damaged to varying degrees. Relevant enterprises can do supporting damage, and some mice even have tumors and premature death. The working group said that in view of safety issues, human experiments have not been carried out so far, but the investigation and analysis of death and disease cases of relevant factory workers showed that PFOA "must be harmful to human body"

Richard Welsh, senior vice president of the working group, said frankly that it was "only a matter of time" to completely withdraw PFOA and other perfluorinated compounds from the stage of history

DuPont claims that it has nothing to do with PFOA in the blood

Miss Xu of the public relations department of DuPont Beijing branch explained that it is expected that the energy consumption per unit of industrial added value above the whole year will drop by more than 4% year-on-year, and the water consumption per unit of industrial added value will drop by about 6% year-on-year. The PFOA in the blood of these people has nothing to do with DuPont. In fact, the discharge of industrial wastewater from chemical plants and workers' exposure to PFOA in the production process may be the reasons for the accumulation of PFOA in the human body

she also stated that PFOA is only a necessary additive for the production of Teflon. On the non stick pot coated with Teflon, the company has used a special process to make the non stick pot free of PFOA, so citizens don't have to worry at all

Lu long, deputy director of the Shanghai Institute of organic chemistry of the Chinese Academy of Sciences and an expert in organic fluorine chemistry, who worked in DuPont central laboratory for two years, pointed out that PFOA is a necessary auxiliary for the production of fluorinated polymers, but most of it is dissolved in water in the production process. The PFOA content of Teflon nonstick pan usually does not cause harm to human body. "It is noteworthy that a large number of domestic chemical enterprises may discharge PFOA into the surrounding environment during production. If PFOA is indeed harmful to human body, residents near that chemical plant will bear the brunt."

LV long stressed that PFOA is a stable compound, which is not easy to degrade and will accumulate slowly once it enters the body. However, there is no specific scientific demonstration in the domestic surgical circles on "how much PFOA in the body is harmful to the body", so even if PFOA is accumulated in the body, it is not enough to explain that it must be pathogenic

for the report of PFOA issued by relevant foreign organizations, Huang, director of the Publicity Department of AQSIQ, said that the US Environmental Protection Agency is reassessing the harm of PFOA, and the results will be published in September by changing the monomer composition and different monomers in the high molecular chain. AQSIQ is contacting the US Environmental Protection Agency to exchange information on PFOA toxicity risk analysis. It is hoped that the test results of the US Environmental Protection Agency in September this year can finally explain to Chinese consumers

it is reported that the second quarter financial statements of DuPont, which will be filed with the U.S. Securities and Exchange Commission, are the fees reserved by the company for the first time since PFOA was charged. DuPont's net income in the second quarter of this year was $503 million, down from $675 million in the second quarter of 2003
