Scientists: Non-stick pot materials are harmful

China Coatings Online News Information:
say non-stick pot materials are potentially harmful. By the end of 2015, some of the most notorious polyfluorocarbons and perfluorocarbons (PFAS) will be completely discontinued in the United States. In 1961, a DuPont toxicologist warned colleagues that rats and rabbits had bigger livers after exposure to their company's increasingly popular Teflon chemicals. Subsequent decades of research have found that there are no safe levels of exposure for animals, and concluded that humans can also get sick after exposure to these chemicals -- and that these substances accumulate in the human body and are difficult to degrade in their natural environment. In other words, the so-called non-stick pot material tends to stick to death.
the Huffington Post reported on May 1st that some of the most notorious polyfluorocarbons (PFAS) will be completely discontinued in the United States by the end of 2015. But environmental health experts warn that another class of PFAS substances with worryingly similar properties is replacing those that have been deactived. "We know that these alternative materials will also be present in the natural environment for a long time," said Arlene Bloom, a chemist at the University of California, Berkeley and executive director of the green science policy institute, a nonprofit. Their degradation is far from over. On
1st, the State of the Environment Observer, a monthly academic journal, published a document entitled "Madrid Statement", signed by more than 200 scientists from 38 countries. The statement singled out the potential hazards of old and new PFAS chemicals. These substances may protect your carpet from getting dirty, keep your food from sticking to packaging or pans, and keep your coat from rain. If you eat a pastry snack over coffee in the morning, the wax paper used to house the snack may be covered with a layer of PFAS. "These chemicals can last in the environment for a long time, so producing them is a very dangerous decision, and using them in highly exposed consumer goods is a disturbing thing," Bloom said.
In an editorial with the statement, Linda Birnbaum, director of the National Poison Administration at the U.S. Department of Health and Human Services, and Philip Groening, a professor of environmental medicine at the University of Southern Denmark, cited the practice of replacing phased chemicals with structurally similar chemicals, such as the recent replacement of BPA with bisphenolS, according to

in an editorial with the statement. Other experts attributed the situation to outdated toxic chemicals legislation, which allowed chemicals to maintain the presumption of "innocence" until proven "guilty". Scientists are calling for global collaboration to limit PFAS production and find safer alternatives.
