Abstract
The presence of asbestos (1332214) bodies, including chrysotile (12001295) fibers, in the lungs of city dwellers was studied. Lung sections from 3000 consecutive autopsies in New York City were examined microscopically for inorganic fibers and the presence of asbestos bodies. Electron microscopic studies were performed on 28 consecutive cases to determine the presence of chrysotile fibers. Uncoated inorganic fibers were present in almost all lungs, and fibers smaller than 1 micron in diameter were found in 35 percent of the cases. Asbestos bodies were identified in about half of the cases. Chrysotile fibers were present in all 28 cases examined, and the number was greater than could be explained by background counts in 24 cases. The authors conclude that chrysotile asbestos is a common contaminant in the lungs of New York City residents and is probably present in lungs of residents in other urban areas. Direct search for chrysotile fibers and fibrils in the lungs is recommended instead of analysis for asbestos body cores.
