"Blackwater" - a film based on true events, about the environment, about human nature. During the viewing process, there is naturally admiration for the protagonist lawyer Robert who insisted on investigating the environmental and human health problems caused by the chemical company DuPont for more than ten years despite people's incomprehension and the risk of touching the interests of big companies and his life. . But at the same time, it was cool. First, DuPont knew that PFOA (a dispersant used in the production process of Teflon), although good in hydrophobicity, could be carcinogenic and have a huge impact on human health. But instead of disposing of leaked PFOA, they use it to make raincoats, carpets, nonstick paint, and hide the truth for profit. After the truth was revealed, they also said that there was nothing in the water, but the truth was obvious. Disregarding health for the sake of profit, the government can also do things against its will for the sake of profit. Why a case takes more than ten years, the darkness and entanglement of interests behind it can be imagined. The second is to worry about our health. PFOA already exists in 99% of people's body and cannot be broken down in the body. Although the film shows that people living downstream of chemical plants and chemical plant workers have obvious symptoms, the European Union and the United States have banned PFOA, but we are still using it. , will it increase the incidence of cancer because of the accumulation of small amounts? Could the increase in cancer incidence in recent years have something to do with this? Or are there other substances causing this? We don't know, but in the continuous development of science, pollution is the only way to go. All we can do is to protect ourselves more and pay attention to and urge the state to manage industrial pollution. ps: Now the non-stick pan coating is mainly Teflon, but the ones produced by big manufacturers will not contain PFOA, and Teflon will decompose and be harmful at temperatures above 260 °C, so as long as the temperature is suitable, there is no problem. In the movie, PFOA and Teflon are a bit confusing, and I was wondering if the pot could be used...
