Examination of the Thermal Decomposition of Chrysotile [PDF]

, 2005
The decomposition of pure chrysotile from Thetford, Quebec heated at constant temperature in air from 200-1000°C for 4 to 720 hours was studied by using X-ray diffraction and optical microscopy techniques.

Assessment of asbestos exposure in Kyrgyzstan through analysis of raw and processed materials, air samples and human lung tissue

Scientific Reports
Asbestos still represents a major public health problem on a global scale. In Central Asia chrysotile is still mined and used, claiming that it is safer with respect to amphibole asbestos within certain concentrations.

Filling of Chrysotile Nanotubes with Metals

, 2017
Nanowires were produced by injection of molten Hg and Pb into chrysotile nanotubes. The breakdown of chrysotile and the surface tension of the molten metals are the limiting factors for the filling procedure. The thermal stability of chrysotile nanotubes

Use of the Ellipsoid of Variographic Anisotropy as a Kinematic Indicator in Rock Massifs Fractured by Faults - the Example of the Cana Brava Chrysotile Asbestos Deposit (Minaçu, GO) [PDF]

Geologia USP. Série Científica, 2011
The parameters of a variogram depend on which direction it is calculated, such as the ellipsoid of variographicanisotropy, whose axes indicate the directions of higher, medium and lower continuity of the variable used to calculate thevariogram ...

Selective Detection and Automated Counting of Fluorescently-Labeled Chrysotile Asbestos Using a Dual-Mode High-Throughput Microscopy (DM-HTM) Method

Sensors, 2013
Phase contrast microscopy (PCM) is a widely used analytical method for airborne asbestos, but it is unable to distinguish asbestos from non-asbestos fibers and requires time-consuming and laborious manual counting of fibers.

AKT/mTOR and C-Jun N-terminal Kinase (JNK) Signaling Pathways Are Required for Chrysotile Asbestos-Induced Autophagy

Free Radical Biology & Medicine, 2014
Chrysotile asbestos is closely associated with excess mortality from pulmonary diseases such as lung cancer, mesothelioma, and asbestosis. Although multiple mechanisms in which chrysotile asbestos fibers induce pulmonary disease have been identified, the

Understanding exposure risk using soil testing and GIS around an abandoned asbestos mine

Annals of Global Health
Background: Abandoned asbestos mines are a potential source of environmental contamination and exposure for nearby residents. The asbestos exposure risk may persist even after the cessation of mining activity if the mine is not properly closed.
