Perfluorinated Chemicals (PFCs) |
Many of us have probably seen news stories about something commonly referred to as PFCs or perfluorochemicals. You may not know exactly what they are, but can probably guess that they have something to do with the environment and your health. The National Institute of Environmental Health Sciences (NIEHS) and the National Toxicology Program (NTP), an interagency testing program headquartered at NIEHS, are studying many of these compounds. |
