Asbestos exposure during uncontrolled removal of sprayed-on asbestos
…bronchoalveolar lavage (lung-washing) fluid held 349 and 50 asbestos bodies per milliliter, versus under 1 expected in people of the general population without obvious asbestos exposure, and all fibers analyzed by electron microscopy were amosite…

Fiber size and number in amphibole asbestos-induced mesothelioma
…of crocidolite fibers, 0.2 X 10(6)/g; these values represent an approximately 250-fold increase over those found in the general population. Crocidolite fibers were significantly narrower than amosite fibers (mean width, 0.13…

A technical comparison of evaluating asbestos concentration by phase-contrast microscopy (PCM), scanning electron microscopy (SEM), and analytical transmission electron microscopy (ATEM) as illustrated from data generated from a case report
…333 asbestos fibers per gram of deparaffinized wet tissue. Both laboratories found asbestos bodies above the level the authors cite as the upper limit expected in the general population. The authors calculated that 97% of the…

Pleural mesothelioma and lung cancer risks in relation to occupational history and asbestos lung burden
We have conducted a population-based study of pleural mesothelioma patients with occupational histories and measured asbestos lung burdens in occupationally exposed workers and in the general population. The relationship between lung burden and risk, particularly…

Kinetics of deposition and clearance of inhaled mineral dusts during chronic exposure
…Nevertheless, the general pattern exhibited by our results for asbestos is markedly similar to that found elsewhere for rats inhaling diesel fume, leading to the suggestion that it is general (and not specific to fibrous dust)…

Tyler asbestos workers: A mortality update in a cohort exposed to amosite
…196, 300), suggesting that exposed workers from this cohort were nearly 2.5-fold (244 %) more likely to die from this cause as the general referent population. The analysis also showed that exposures of short duration (

Mortality experience of amosite asbestos factory workers: dose-response relationships 5 to 40 years after onset of short-term work exposure
…job that the worker had in the factory. Whichever measure of dosage is used, it was found that, in general, the lower the dose, the longer it took for adverse mortality to become evident and, also…

Effects of asbestos on the random migration of rabbit alveolar macrophages
…indicates that fibers can be toxic for AM through extracellular membrane contact. In general the results from the viability studies paralleled the migration inhibition observations. None of the asbestos preparations induced a burst in the hexose…

Human mesothelioma cells and asbestos-exposed mesothelial cells are selectively resistant to amosite toxicity: a possible mechanism for tumor promotion by asbestos
…cells that were only immortalized by SV40. The sensitivity of normal mesothelial cells to asbestos does not appear to be simply a result of general fragility of the mesothelial cells, since similar levels of hydrogen peroxide…
