Asbestos in the air: a housing boom stirs up natural asbestos in California
Article Abstract:
Increased housing development in the Sierra foothills of Northern California has exposed the threat of asbestos poisoning from the asbestos-rich hills of the area. High levels of tremolite and other high-asbestos rocks are present in the area. The need for legislation regulating naturally-occurring asbestos is highlighted, and state reforms in Virginia and California are considered.
