PFOAs, also known as perfluoro-octanoic acid, which is used the manufacture of stain-resistant fabrics and carpets, may make people more allergic to other things in their environment according to Jean Meade and colleagues at the National Institute for Occupational Safety and Health in Morgantown, West Virginia. In an animal experiment, those who were exposed to PFOAs produced a greater allergic response to egg allergens than those who went unexposed.

Dupont, the leading user of PFOAs of course denied this report vehemently. What I found interesting that while they denied this issue, they did admit that their assertion was not based on any research they did on the subject. PFOAs are found in the blood of everyone out there, but according to researchers, is only found in very small amounts from carpets and upholstery.

My thought on where it comes from is the same as the issue of global pollution; a little bit doesn’t harm the environment, but a little here and a little there and pretty soon you don’t have a little anymore.
