F. Knox and J. Beattie Arch Ind Hyg & Occ Med 10 30-36 . July 1954 - The particle distributions in the incombustible and insoluble residues from the lungs of 27 persons who had been exposed to asbestos dust were determined The number of particles with greatest lengths in excess of 26 microns was considerable up to the eighth year after the last exposure to asbestos dust and then sharply fell The number of particles within the size ranges of five microns and less and between five and 15 microns remained constant over a very long period in those cases which showed no sign of asbestosis or minimal fibrotic change The cases of severe asbestosis showed a significant rise in the numbers of such particles It is considered that the mechanism which is concerned with the production of human asbestosis is not the same as that which is responsible for the production of asbestotic changes in experimental animals exposed to high concentrations of asbes- tos dust The appearance of such changes seems to be related to the breakdown of asbestosis bodies which may liberate some fibrogenic agent -- Authors summary t mie Way it. ji et fit i iD We Nj I 222 Mineral Content of the Lungs after Exposure to Asbestos Dust J.
