Estimating past inhalation exposure to asbestos: a tool for risk attribution and disease screening [PDF]

, 2017
Introduction: Late presentation is common in mesothelioma. Reliable assessment of past exposure to asbestos is a necessary first step for risk attribution and for the development of a future screening programme. Such a programme could maximise access

Health risk of chrysotile revisited [PDF]

Critical 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 ...

Characterization of Serpentines from Different Regions by Transmission Electron Microscopy, X-ray Diffraction, BET Specific Surface Area and Vibrational and Electronic Spectroscopy

Fibers, 2019
Serpentinite powdered samples from four different regions were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), SBET and porosity measurements, UV-Vis and Infrared Spectroscopy of the skeletal region and surface OH groups.

Occupational cohort study of current and former workers exposed to chrysotile in mine and processing facilities in Asbest, the Russian Federation: Cohort profile of the Asbest Chrysotile Cohort study.

PLoS ONE, 2020
A historical cohort study in workers occupationally exposed to chrysotile was set up in the town of Asbest, the Russian Federation, to study their cause-specific mortality, with a focus on cancer. Chrysotile has different chemical and physical properties

Ethanol fermentation of a diluted molasses medium by Saccharomyces cerevisiae immobilized on chrysotile

Brazilian Archives of Biology and Technology, 2003
In this work, the catalytic role of chrysotile support on the acceleration of alcoholic fermentation under non-aseptic conditions by Saccharomyces cerevisiae was investigated. The fermentation medium employed consisted only of diluted sugar-cane molasses.

Phyllosilicate Infrared Spectral Features as Tracers of Aqueous Alteration in CM Chondrites and Implications for Remote Sensing of Hydrated Asteroids

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract CM (Mighei‐type) carbonaceous chondrites host abundant OH/H2O‐bearing phyllosilicates formed from water‐rock reactions in primitive planetesimals. Their infrared (IR) spectral features resemble those of C‐type asteroids, making laboratory analyses of CMs essential for interpreting asteroid observations.

Synthesis and performance of polyurethane/silicon oxide nano-composite coatings

Science and Engineering of Composite Materials, 2019
Chrysotile asbestos has excellent physical and chemical properties, but its high biotoxicity is very damaging to human health, due to its durability, high aspect ratio, and the exist of iron.

Trace element geochemistry of peridotites from the Izu-Bonin-Mariana Forearc, Leg 125

, 1992
Trace element analyses (first-series transition elements, Ti, Rb, Sr, Zr, Y, Nb, and REE) were carried out on whole rocks and minerals from 10 peridotite samples from both Conical Seamount in the Mariana forearc and Torishima Forearc Seamount in the Izu ...

Electrical Conductivity During Controlled Deformation at Upper‐Mantle Conditions: First Experimental Achievements in a Griggs‐Type Apparatus

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Electrical conductivity measurements on well‐characterized materials in the laboratory allow accurate interpretations of high‐conductivity anomalies within the lithosphere and asthenosphere, both affected by substantial deformation over geological times.

Petrography of phosphates in CI and CY carbonaceous chondrites

Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2594-2622, November 2025.
Abstract Phosphate minerals are significant carriers of volatiles (e.g., OH) and halogens in chondritic material; however, their origin in most groups of carbonaceous chondrites remains poorly characterized. We have determined the abundance, morphology, texture, and composition of phosphate grains in aqueously altered CI chondrites and in hydrated and ...
