Perfluorochemicals
Perfluorochemicals (PFCs) are a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. Fluoropolymer coatings can be used in such varied products as clothing, furniture, adhesives, food packaging, heat-resistant non-stick cooking surfaces, and the insulation of electrical wire. Many chemicals in this group, including perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), have been a concern because they do not break down in the environment, and they build up in wildlife. PFCs have been found in rivers and lakes and in many types of animals on land and in the water. Human
health effects from exposure to low
environmental levels of PFCs are unknown. Studies of laboratory animals given large amounts of PFCs have found that some PFCs may affect growth and development, reproduction, and injure the liver. More research is needed to assess the human
health effects of exposure to PFCs. During the last 15 years or so, scientists have found trace levels of perfluorinated chemicals (PFCs) nearly everywhere in the environment. Low levels are found in people and animals around the globe. In 2004 in Minnesota, PFCs were first found to have contaminated drinking water supplies in parts of the eastern Twin Cities.
