Associated minerals in chrysotile deposits and their potential health risks [PDF]

open access: yesFrontiers in Public Health
Chrysotile samples from different deposits and the UICC-A and UICC-B standards have been analyzed by a procedure in which the chrysotile is removed by successive treatments in hydrochloric acid and sodium hydroxide, followed by transmission electron ...

Cytotoxicity of Heated Chrysotile [PDF]

open access: diamondEnvironmental Health Perspectives, 1974
Cytotoxicity and hemolysis were studied in chrysotile and quartz. The biological activity of the surface seemed to be different between chrysotile and quartz. Quartz lost its cytotoxicity on heating over about 500 degrees C. However chrysotile showed remarkable toxicity and induced hemolysis on heating between 650 and 800 degrees C, compared with the ...

Design and application of environmentally effective concrete with usage of chrysotile-cement waste

open access: yesMATEC Web of Conferences, 2016
Construction is resource-demanding industry, characterized by a large volume of waste. Particularly chrysotile cement waste obtained both in production and in dismantling over age chrysotile-cement products: corrugated asbestos boards and flat sheets ...

Tubular-Shaped Stoichiometric Chrysotile Nanocrystals

open access: yesChemistry - A European Journal, 2004
Stoichiometric chrysotile tubular nanocrystals have been synthesized as possible starting materials for applications toward nanotechnology, and as a standard reference sample for the investigation of the molecular interactions between chrysotile, the ...

Health risk of chrysotile revisited [PDF]

open access: yesCritical Reviews in Toxicology, 2013
This review provides a basis for substantiating both kinetically and pathologically the differences between chrysotile and amphibole asbestos. Chrysotile, which is rapidly attacked by the acid environment of the macrophage, falls apart in the lung into short fibers and particles, while the amphibole asbestos persist creating a response to the fibrous ...

Modification of Chrysotile Surface by Organosilanes: An IR–Photoacoustic Spectroscopy Study

open access: yesJournal of Colloid and Interface Science, 2001
Chrysotile and its dimethylsilyl (DMS) and dimethylphenylsilyl (DMPS) derivatives were studied by Fourier transform infrared–photoacoustic spectroscopy. In the Si–O stretching region of chrysotile a new band was revealed at 985 cm−1, besides absorptions ...

Research progress on mechanism of epithelial mesenchymal transition induced by chrysotile exposure

open access: yes环境与职业医学, 2023
As a mineral material widely used in life, chrysotile is a public health concern for its fibrogenicity and carcinogenicity. Currently, more than 50 countries have completely banned the import and use of chrysotile, but China is still the world's largest ...
