Establishment of Vegetation on Serpentine Asbestos Mine Wastes, Southeastern Quebec, Canada
The Journal of Applied Ecology, 1977SUMMARY The serpentinic tailings from asbestos mines in southeastern Quebec cover 5.5 km2 and are largely devoid of vegetation. The wastes are close to settlements and are a potential health hazard; it is therefore desirable to develop revegetation techniques that will produce a sustained plant cover.

Meditsina truda i promyshlennaia ekologiia, 1999The article presents summarized data of long-standing research of work conditions, asbestosis occurrence, and epidemiology of malignancies in "URALASBEST" enterprises extracting and utilizing asbestos. The research served as a base to elaborate and put into practice a complex of sanitary, technical, medical and biologic measures in various asbestos ...

There is considerable evidence that alveolar macrophages play a pivotal role in the pathogenesis of asbestosis (Kagan 1985, Kagan 1988), since these phagocytic cells are a notable feature of histologic lesions at sites of asbestos deposition in the lungs (Davis 1963, Brody et al. 1981, Oghiso et al. 1984).

Serpentinitic sediments rich in chrysotile asbestos, from a natural landslide in the Sumas River Watershed in Washington State, are deposited on agricultural land during flooding events, creating a health concern for the rural population. The sediments have a chemical composition of high magnesium (Mg), nickel (Ni) and chromium (Cr) and high pH values ...

ABSTRACT Petrography of mélange matrix and clastic sedimentary rocks in coastal California reveals the occurrence of detrital serpentine and detrital asbestiform sodic amphibole (glaucophane). Many sandstones of the Franciscan Complex have small amounts of detrital serpentine, with amounts of up to several percent in some cases. Detrital

AbstractA chrysotile disc is proposed as the fundamental seed structure for the formation of chrysotile asbestos fibres, polygonal serpentine fibres and polyhedral lizardite spheres. The curvature, fivefold symmetry and hydrogen-bonding alignment of the layers in the seed disc control the formation of the 15 or 30 sectors in polygonal serpentine and ...

The authors followed changes in clinical course of asbestosis, comparing groups of individuals working in exposure to chrysotile-asbestos dust, patients having so-called late asbestosis and reference group (individuals with absent or minimal roentgenologic changes in lungs). Analysis of 530 case histories proved increase of average length of service in

Abstract The purpose of this study was to determine if minimal exposures to amphibole (crocidolite) and serpentine (chrysotile) asbestos fibers significantly increase the incidence and rate of malignant mesothelioma (MM) onset in mice with a germline heterozygous Bap1 mutation, and to assess the effect of the resulting gene × environment
