Pulmonary asbestos and non-asbestos fiber concentrations in autopsied inhabitants in Pohang, Korea.
To establish reference values for pulmonary asbestos and non-asbestos fiber concentrations in rural Korean residents, and their comparison with those of urban Korean residents and the Japanese, autopsied lung samples from 22 subjects (20 males and 2 females), in Pohang, without known occupational asbestos exposure histories, were analyzed for asbestos and non-asbestos fibers, using transmission electron microscope equipped with an energy dispersive X-ray analyzer. Chrysotile was the major fiber type found in the lungs of the subjects. The residents in Pohang had significantly lower asbestos and non-asbestos fiber concentrations than the Korean urban residents. The Koreans had significantly lower asbestos and non-asbestos fiber concentrations than the Japanese.
