One interesting study is called, Specificity of asbestos-induced chromosomal aberrations in short-term cultured human mesothelial cells - Cancer Genetics and Cytogenetics Volume 41, Issue 1, August 1989, Pages 33-39 by Kenth Olofssona and Joachim Mark, a Department of Pathology and Cytogenetics, Central Hospital, Skövde, Sweden. Another study is called, Recovery of ingested asbestos fibers from the gastrointestinal lymph in rats - Environmental Research Volume 22, Issue 1, June 1980, Pages 201-216 by P. Here is an excerpt: Abstract - Using the transmission electron microscope, asbestos fibers have been assessed in lymph fluid collected from the thoracic lymph duct in five groups of rats previously exposed to asbestos fibers by ingestion . All the rats of the chrysotile group were positive animals with recovery rate values ranging from 6.9 10 7 to 3 10 5 90% of the fibers being recovered during the first 16 hr following the gavage . Of the 15 rats comprising this group, 13 were positive with maximum daily recovery rates ranging from 2.1 10 7 to 2.1 10 6. A group of eight rats fed the same kind of diet but containing a higher proportion of long fibers, showed only four positive animals, however, they had higher daily recovery rates ranging from 1.9 10 5 to 2.1 10 4. This study demonstrates the passage of chrysotile and crocidolite fibers across the gastrointestinal wall, with the passage rate being higher for long fibers than short ones. Here is an excerpt: Abstract - Studies on the behavior of asbestos fibers within tissues have shown that the only cells that regularly contain asbestos are macrophages and their derivatives. Another study is called, Static electrification of airborne asbestos: A study of its causes, assessment and effects on deposition in the lungs of rats - American Industrial Hygiene Association Journal, Volume 42, Issue 10 October 1981, pages 711 - 721 by J. Here is an excerpt: Abstract - The paper describes a series of experiments carried out in the laboratory to investigate how asbestos fibres might become electrostatically charged during the process of being made airborne, the magnitude and polarity of the charge per fibre, and the effect on lung deposition in rats.
