Abstract
The Bureau of Mines particulate mineralogy unit, in cooperation with the Environmental Protection Agency (EPA), conducted a round robin program to evaluate the reliability of analyses of asbestos- containing building materials by polarized light microscopy. This microscopic technique was selected by EPA as the principal analytical method for asbestos identification and quantification in their program to evaluate the potential health risks from exposure to airborne asbestos in public buildings. Results of the round robin show a need for monomineralic reference samples of asbestos and non-asbestos components of these materials to aid in identification training. Also necessary are bulk standards containing known amounts of asbestos to be used in verification and quality control of quantification techniques.
