...sols. How toxic is Teflon? After years of the production companies like Dupont insisting that Teflon is safe, the scientific community is anticipates that Teflon may not be as safe as once thought. Research suggests that while the solid form of Teflon may not be toxic, the off-gas chemicals released from the material breaking down are. I could not find the LC50 or LD50 values in relation to humans but I managed to find a LC50 value for a rat which was 40000 ppm/4h. A SAX toxicity evaluation reported Teflon as mildly toxic by inhalation. According to test studies, A Teflon coated cooking pan can reach 721 degrees F under normal cooking conditions in just five minutes. This temperature is hot enough for Teflon to start breaking down releasing its toxic off gases. Dupont throughout the years, have insisted that under normal cooking conditions the temperatures for which the Teflon coated pans would start breaking down are unable to be reached. Teflon coated pans start off gasing toxic particles at 446 degrees F. At 680 degrees F the six toxic gases, including 2 carcinogens (cancer causing chemicals), 2 global pollutants and MFA which is a chemical lethal to humans at even low doses. Over the Past 50 years Dupont has denied that Teflon coating produce hazardous vapors by normal use. To humans the off gases from Teflon coated cook wear can cause polymer fume fever. Polymer fume fever consists of common flu like symptoms which dissipate after a couple of days. Due to the similarity to the common flu most cases of polymer fume fever go unreported. The gases released by Teflon can however have a deadly effect on pet birds. After years of denying Teflon releases toxic gases, the Dupont Company within the last few years acknowledges that the Teflon off-gases can kill pet birds, but side tracks the information in public service brochures. As of now Teflon is not listed as a carcinogen although tests have shown that 2 chemicals released as off-gas (PFOA and TFE) are linked to causing cancer or tumors in lab studies. The culmination of off-gas chemicals in food and the potential effects of inhalation exposures to humans have yet to be studied, but several off the off-gas components are considered highly toxic to humans relati...
