Decreased lung function in long-term asbestos cement workers: a cross-sectional study
…The primary type of asbestos used was chrysotile and the general dust level in the two decades 1950-1970 seems to have been around 10 mg/m3 while the asbestos fiber concentration averaged 2 fibers/ml…

A comparison of the ferruginous body and uncoated fiber content in the lungs of former asbestos workers
…2 million uncoated amphibole fibers per gram. Light microscopy examination of adjacent tissues confirmed mild fibrosis in both workers. Ferruginous bodies serve as a general marker for asbestos exposure. However, our data suggest that their absence…
