Amphibole fibres in Chinese chrysotile asbestos

Investigation of the chrysotile fibres in an asbestos cement sample

Desquamative interstitial pneumonia associated with chrysotile asbestos fibres.

The drywall construction trade has in the past been associated with exposure to airborne asbestos fibres. This paper reports a drywall construction worker with 32 years of dust exposure who developed dyspnoea and diminished diffusing capacity, and showed diffuse irregular opacities on chest radiography. He did not respond to treatment with corticosteroids. Open lung biopsy examination showed de...

Cancer Mortality in Chinese Chrysotile Asbestos Miners: Exposure-Response Relationships

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. Causes and dates of death were further verif...

Chrysotile Asbestos and Mesothelioma

Assuming an average latency of 42 years, the authors predict that incidence rates will peak in 2009 and that diagnoses will peak in 2014. However, they caution that ongoing use of chrysotile asbestos (which has been implicated but not conclusively established as a cause of mesothelioma) and the release of asbestos fibers from older buildings during demolition or reno­ vation may slow the projec...

Role of associated mineral fibres in chrysotile asbestos health effects: the case of balangeroite.

OBJECTIVES To evaluate the biodurability of balangeroite, present as contaminant of chrysotile asbestos in the Balangero mine, in order to have indication whether it might have been a confounding factor in the association of the mesothelioma cases reported among mine workers and employees. METHODS The modifications taking place following incubation of the fibres in simulated phagolysosomal fl...
