Asbestos: The Chemistry of the Dust and of the Pulmonary Pathology

This was a textbook chapter, not a research study. It reviewed the chemistry of asbestos dust and of the lung disease asbestosis. It described the main fiber types (chrysotile, anthophyllite, amosite, crocidolite, tremolite and actinolite) and how asbestos bodies form in the lung. The chapter said the coating around an asbestos needle was probably a protein. It said that the longer a patient survived after last exposure, the fewer large particles and the more small ones were found in the lungs. It noted that benzpyrene, a cancer-causing compound, had been found with crocidolite but not with chrysotile or silica, and called this a provocative finding. It said a higher than expected proportion of asbestosis cases developed carcinoma or mesothelioma of the lung or pleura, and that advanced cases tended to be short of oxygen. The authors concluded that asbestosis is progressive, has no effective curative therapy, and becomes established in the lung before warning signs appear, so the basic approach should be prevention. The authors noted that the human significance of the guinea pig work was unclear.

From J-M's medical library

This copy comes from the Johns-Manville medical library. It was among the papers J-M kept in its medical library without an index entry.

We publish pages from a book for research and commentary: it shows what the medical literature in a leading asbestos company's own library said on the subject, and when. Our summary above is our own reading of it. The copyright stays with the publisher.
