Asbestos Mining Chrysotile
ASBESTOS (CHRYSOTILE, AMOSITE, CROCIDOLITE,
One possible explanation for these negative findings for chrysotile is that South African chrysotile asbestos may contain relatively little tremolite (Rees et al., 1992). Another possible explanation is that chrysotile mining began later, and production levels were lower than in

Mortality in a Chinese chrysotile miner cohort
Background: Few data were available to address cause-specific mortality in asbestos miners in China. This study observed a cohort of workers from the largest chrysotile asbestos mine to evaluate the association between asbestos exposure and cause-specific mortality. Methods: The cohort consisting of 1,539 male workers was observed from 1981 to ...

The San Vittore Mount (45°17'32"N 7°31'01"E), an asbestos-rich serpentinitic outcrop, has been exploited over a long period of time for chrysotile asbestos extraction and constituted the largest and most productive chrysotile asbestos mine in western Europe (e.g. Virta, 2005). The mining area is nowadays characterised by an open pit which is ...

Chrysotile: Mineral information, data and localities.
This mineral is known to be a respirable carcinogen, and is the most common form of asbestos. Exposure to very dusty air or long-term exposure to low level airborne dusts containing fine fibres of chrysotile has been found to cause a high risk of serious lung disease including mesothelioma and lung cancer.

Asbestos Exposure of Chrysotile Miners and Millers in ...
Introduction. The Balangero (Italy) chrysotile asbestos mine, the largest in Western Europe, started activity in 1917 (Rubino et al., 1979; Silvestri et al., 2001).Ghezzi et al. described the occurrence of asbestosis, whereas Rubino et al. first reported on cause-specific mortality of Balangero miners and millers. Later updates were published (Piolatto et al., 1990; Pira et al., 2009, 2017).

Objective: This study was conducted to assess the relationship of mortality from lung cancer and other selected causes to asbestos exposure levels. Methods: A cohort of 1539 male workers from a chrysotile mine in China was followed for 26 years. Data on vital status, occupation and smoking were collected from the mine records and individual contacts.
