Mineral Found in Roads Causes Mesothelioma

According to information presented at the 2010 Chicago Multidisciplinary Symposium in

Thoracic Oncology, people who have been exposed to an organic mineral called erionite

found in over 300 miles of North Dakota road have a significantly increased risk of developing mesothelioma. Mesothelioma is a malignant form of lung cancer that develops from the protective lining of organs and is usually caused by exposure to asbestos. Like asbestos exposure, the erionite found in the pavement of North Dakota roads can cause malignant mesothelioma by simply inhaling small fibers of the mineral.

Erionite deposits are also present in California, South Dakota, Oregon, Arizona and Nevada. It is an organic mineral whose chemistry has become altered by weather and ground water. It is usually white or clear and may look like translucent grass blades.
