Teflon Chemicals Found in Humans

Chemicals used in Teflon and Scotchguard are showing up in the bloodstream of humans throughout the world, with higher levels in the United States and other highly developed nations, according to a new study.

The chemicals -- perfluoronated compounds -- have been used for decades with very little government oversight. Scientists say they are surprised at the chemicals' pervasiveness in the environment, which they said raises concerns about their potential impact on public health.

Perfluoronated compounds have been found in the blood of virtually every person tested for them in the United States, including children as young as 2. The compounds have been linked to cancer, developmental problems, liver damage and other ailments in animals, though there is no general agreement about their effects on humans.
