Crocidolite dissolution in the presence of Fe chelators: implications for mineral-induced disease
… as asbestosis, mesothelioma, and lung cancer. Crocidolite, the asbestiform counterpart of the amphibole riebeckite, is particularly dangerous in cases of chronic exposure. Its pathogenic activity may result from the interaction of the fiber surfaces with physiological fluids. Fe removed from …

The genesis of the blue amphibole asbestos of the Union of South Africa.
The blue amphibole asbestos, crocidolite, which occurs as interbedded seams in banded ironstones of the Lower Griquatown stage of the Transvaal System in the Northern Cape Province, is the finely fibrous form of the soda-amphibole riebeckite. Despite the widespread occurrence of the Precambrian …

The Role of Silicates in Interstitial Lung Disease
… of asbestos induced ILD. A cell model to study crocidolite-induced toxicity was developed using LA-4 cells, previously characterized as alveolar type II cells. LA-4 cells when exposed to crocidolite had a decrease in viability and an increase in the release of LDH and 6-keto PGF1α, a …

Problems associated with the quantitative estimation of asbestos.
… of the two U.I.C.C. standard reference samples, Crocidolite and Anthophyllite, as internal standards in X ray analytical methods. 3) The examination of the X ray diffraction pattern of the dust collected from an asbestos worker's lungs and the use of the U.I.C.C. standards as internal and …

A case-control study of mesothelioma in South Africa
… exposure, 20 were from the NW Cape (a crocidolite mining region). Fifty eight percent had occupational exposure, three of whom had mined amosite. The relative risks associated environmental exposure in the NW Cape were larger than for environmental exposure in the NE Transvaal: 21.9 …

THE ROLE OF THE MACROPHAGE IN ASBESTOS INDUCED AUTOANTIBODY PRODUCTION
… stress in murine macrophages similar to crocidolite asbestos. However, Libby asbestos induces distinct cellular effects compared to crocidolite asbestos. Therefore, the cellular effects of amphibole asbestos may be a combined consequence of its chemical composition as well as the …

Raman spectroscopic characterisation of inorganic fibres and particles and their coverage by wetting agents.
… such as amosite, anthophyllite, chrysotile, crocidolite and tremolite gave distinct spectra. There were no very distinct differences between the spectra of asbestos fibres and their non-fibrous forms except sometimes in the v(OH) stretching region or band width in the case of tremolite. The …

Caratterizzazione chimica e microstrutturale di minerali fibrosi ad alto impatto per l'inquinamento ambientale
… (crisotilo, tremolite, actinolite, amosite, crocidolite, antofillite), ampiamente utilizzati nel passato per la produzione di materiali contenenti asbesto. In Italia, la normativa vigente (L. 257/92) vieta l’estrazione, l’uso e la commercializzazione dell’asbesto e di tutti i materiali …
