Free radical activity of natural and heat treated amphibole asbestos
Journal of Inorganic Biochemistry, 2001The amphibole minerals amosite and crocidolite were subjected to calcination and to hydrothermal treatment in order to study the effect of these heat treatments on the ability of the minerals to trigger formation of free radicals, which is known to be a main factor causing asbestosis and other asbestos-induced diseases.

Effect of Size Fractionation on the Toxicity of Amosite and Libby Amphibole Asbestos
Toxicological Sciences, 2010Abnormally high incidences of asbestos-related pulmonary disease have been reported in residents of Libby, Montana, because of occupational and environmental exposure to asbestos-contaminated vermiculite. The mechanism by which Libby amphibole (LA) causes pulmonary injury is not known.

Surface chemistry and surface reactivity of fibrous amphiboles that are not regulated as asbestos
Analytical and Bioanalytical Chemistry, 2012Three fibrous amphiboles that are not regulated as asbestos--two from Biancavilla (Sicily, Italy) and one from Libby (MT, USA)--were studied in order to establish relationships between surface chemistry and surface reactivity. The three fibrous samples, plus one prismatic fluoro-edenite from Biancavilla that was used for comparison, were investigated ...

Surface Charge Heterogeneity in Amphibole Cleavage Fragments and Asbestos Fibers
Science, 1980Aspect ratio and electrophoretic mobility data for amphibole particles reveal that short fibers and blocky cleavage fragments have a smaller net charge than highly elongated particles. Asbestos fibers and cleavage fragments of the same dimensions exhibit the same net negative surface charge but positively charged ends and negatively charged lateral ...

The nature of electron diffraction patterns of amphibole asbestos and their use in identification
Environmental Research, 1979Abstract The reported insensitivity of electron diffraction patterns of single amphibole fibers to tilts of ±20° ( Skikne et al. , 1971 ; Chisholm, 1973 ; Seshan, 1976 ) does not occur when the fibers are thin enough, and Seshan's explanation of it is incorrect.

Proceedings of the Geologists' Association, 2007
An increase in the incidence of asbestos-related diseases in the general population from non-occupational exposure to the various asbestos fibre-types has been a concern since the identification of riebeckite asbestos (commonly referred to as blue asbestos or crocidolite in the medical literature) as an aetiological agent in human mesothelioma.

Annals of Occupational Hygiene, 1990
In an attempt to determine whether there exists a threshold asbestos dose below which asbestosis does not occur, data on 807 men who had worked on amphibole asbestos mines and undergone autopsy were analysed. When exposure was expressed as fibre-years no asbestosis was found at autopsy when exposure was up to 2 fibre-years, even after 31-45 years of ...

Biological activity of synthetic amphibole asbestos.
Polish journal of occupational medicine and environmental health, 1992The carcinogenic and fibrogenic activity of four samples of synthetic amphibole asbestos with different chemical structure was examined in white rats. Pleural mesotheliomas were found: in 11 out of 27 rats (37.8%) treated with magnesium asbestos; in 4 out of 24 animals (6.7%) for nickel asbestos; 13 out of 22 (59.1%) for cobalt asbestos; and in the ...

Research in optical and thermal˗optical properties of alkaline amphibole asbestos
Bulletin de Minéralogie, 1981This paper deals with the researches of the main species of Chinese asbestos — winchite asbestos, calcium-magnesioriebeckite asbestos, and magnesioriebckite asbestos. Examination of them by various methods — crystallo-optical, thermo-optical, chemical and crystallochemical, X-ray, weight loss, infra-red absorption and statistics has given some ...
