Autopsy lung tissue specimens of occupationally and nonoccupationally exposed people are examined for number of mineral fibers in the optical range and submicronic (electron microscopic) range, number of fibers less than 5 microns in length, and number of chrysotile (12001295) fibers. No relationship appears between the concentration of mineral dust and the concentration of mineral fibers in the lungs. The percentage of chrysotile fibers in lungs from nonoccupationally exposed people average only about 7 percent as compared to an estimated 95 percent or more for asbestotic lungs. The concentration of asbestos (1332214) fibers associated with early asbestotic inflammation is not determined.
