C8 and c6

222 Scientists call for the reduced use of stain and waterproofing chemicals in clothing. Highly fluorinated chemicals (also known as PFCs or PFASs or C8 and C6) are now everywhere – deep in the ocean, on mountaintops and in nearly all living creatures. A professor of environmental chemistry at the University of Toronto, has said that this class of chemicals will last in the environment for geological time – that is, millions of years – perhaps even longer than humanity. Making and using chemicals that could be harmful and persist longer than mankind is a serious matter, and it should not be undertaken lightly.
