Researchers find EDC levels are higher indoors than outdoors

Excerpt: Concentrations of endocrine-disrupting chemicals (EDCs) -- found in many everyday products and of concern due to potential health hazards -- are higher indoors than outdoors, according to a new study.

But they are equally present, the researchers found, in an urban, low-income community near an oil refinery and in a rural, affluent coastal community without much industry.

"The higher your exposure to consumer products, the higher your exposure to endocrine-disrupting chemicals," researcher Ruthann Rudel, director of research at the Silent Spring Institute, Newton, Mass., tells WebMD.

''The indoor consumer product exposure [to these chemicals] is more pervasive and consistent than we thought," she says of the study findings. "It cuts across geography and demography, based on this somewhat limited sample."

The study is published online in Environmental Science & Technology.
