Chrysotile biopersistence in the lungs of persons in the general population and exposed workers
…form, with both fibers and fibrils > 5 microns in length. Comparison of the lung fiber content of occupationally exposed persons with that of the general population showed marked qualitative and quantitative differences. Fibers are durable…

Asbestos Lung Burden in Necroscopic Samples from the General Population of Milan, Italy
…No AB were found in subjects younger than 30 years. Our study demonstrated detectable levels of asbestos fibres in a sample taken from the general population. The significant increase with age confirmed that amphibole fibres are…

Fiber size and number in workers exposed to processed chrysotile asbestos, chrysotile miners, and the general population
…chrysotile ore, 20 long-term chrysotile miners, and 20 members of the general population (controls). Significantly greater amounts of both chrysotile and tremolite were found in processed-ore workers and miners than in controls. On average…

Nature of exposure to chrysotile
Fibres in general, and chrysotile fibres in particular, have properties that set them apart from other airborne particles in terms of their aerodynamic behaviour and the nature of their interactions with cells and fluids in vivo…

Tissue burden of asbestos in nonoccupationally exposed individuals from east Texas
The potential for asbestos exposure among members of the general population is appreciable, considering its widespread use in many products. This study examined tissue burden of asbestos in such a population. A group of 33 individuals…

Asbestos lung burden and asbestosis after occupational and environmental exposure in an asbestos cement manufacturing area: a necropsy study
This necropsy (autopsy) study examined lung tissue from the consecutive autopsies done at the General Hospital of Casale Monferrato, Italy, home to a large asbestos cement factory, from July 1985 to July 1988. Of 55 autopsies…
