Asbestos : technical information sheet : ATSDR evaluation of community-wide exposure of naturally occurring asbestos

El Dorado Hills is one of many areas throughout the United States that has naturally occurring asbestos (NOA) in local soil and rock formations. Research on people who worked with commercial asbestos in the past has proven that breathing in asbestos increases the risk of cancer and respiratory disease. Some researchers believe the type of asbestos found in El Dorado Hills\u2014amphibole asbestos\u2014is more potent in causing disease than other types of asbestosATSDR was involved in evaluating NOA exposuresat Oak Ridge High School in El Dorado Hills in 2004- 2006. Local residents, academic researchers, and environmental and public health agencies have expressed concern about potential community exposures to NOA in the wider community aroundEl Dorado Hills. Activity-based sampling conducted by the U.S. Environmental Protection Agency (EPA) in 2004 showed that people performing typical outdoor recreational activities could breathe in high levels of NOA, compared to reference samples. Community members asked ATSDR what this finding meant to their health and what they should do to protect their health.Publication date from document properties.CS225087-Atechinfosheetrev72011508.pdf201
