What struck me most about the film was that it was actually a very recent event, and it has continued to this day. Looking at the years in the movie that kept sliding one after another, in addition to cold hands and feet, I was deeply disappointed. PFOA, which is constantly mentioned in the film, is a synthetic surfactant used in the manufacture of non-stick coatings such as Teflon, and is also widely used in daily necessities such as kitchenware, food packaging bags, car seals, etc. . The problem with this synthetic chemical is that it may cause cancer (probably link). In the internal data of chemical giant DuPont, as early as decades ago, research data continued to show that PFOA caused cancer and tumors in animal experiments, and at least two cases of fetal facial deformities occurred in pregnant female workers exposed to PFOA. DuPont has never published any information on the toxicity of PFOA and continues to dump and release this industrial waste in drinking water sources, soil, and air.
