Abstract

To provide an estimation of asbestos exposure among normal Koreans and a criterion for determining occupational asbestos exposed diseases, pulmonary fiber contents of both asbestos and nonasbestos types were evaluated in 20 Korean subjects with no known occupational history of asbestos exposure. Pulmonary fiber contents were analyzed by transmission electron microscopy with energy dispersive X-ray analysis after using the low temperature ashing procedure. Chrysotile fiber (65.5%) was the major fiber type found in the lungs of Korean subjects. Asbestos fiber concentrations found in males and females were 0.30 x 10(6) fibers/g of dry lungs and 0.15 x 10(6) fibers/g of dry lungs, respectively,showing a geometric mean concentration of 0.26 x 10(6) fibers/g of dry lung tissue. Non-asbestos fiber contents found in males and females were 8.02 x 10(6) fibers/g of dry lungs and 7.85 x 10(6) fibers/g of dry lungs, respectively, with a geometric mean concentration of 7.98 x 10(6) fibers/g of dry lungs. There was no difference in asbestos content in lungs among various age groups. Comparing these results with Japanese male (2.11 x 10(6) fibers/g of dry lung) and female subjects (1.38 x 10(6) fibers/g of dry lung), Korean male and female subjects had much less asbestos in their lungs.
