Chrysotile effects on human lung cell carcinoma in culture: 3-D reconstruction and DNA quantification by image analysis

BMC Cancer, 2008
Background Chrysotile is considered less harmful to human health than other types of asbestos fibers. Its clearance from the lung is faster and, in comparison to amphibole forms of asbestos, chrysotile asbestos fail to accumulate in the lung tissue due ...

Identifying the reactive sites of hydrogen peroxide decomposition and hydroxyl radical formation on chrysotile asbestos surfaces

Particle and Fibre Toxicology, 2020
Background Fibrous chrysotile has been the most commonly applied asbestos mineral in a range of technical applications. However, it is toxic and carcinogenic upon inhalation. The chemical reactivity of chrysotile fiber surfaces contributes to its adverse

Evaluation of Mineral Carbonation of Asbestos-Tex and Analysis of Airborne Asbestos Concentrations

Buildings, 2022
Asbestos is a human carcinogen that causes diseases, such as lung cancer and malignant mesothelioma. In Korea, approximately 1.23 × 109 kg of asbestos raw materials was imported for about 30 years.

Mesothelioma risk among those exposed to chrysotile asbestos only and mixtures that include amphibole: a case–control study in the USA, 1975–1980

Occupational and Environmental Medicine, 2020
Objectives Occupational asbestos exposure is causally linked to mesothelioma. However, whether exposure to only chrysotile asbestos is associated with mesothelioma risk, and the heterogeneity in risk by different fibre types/lengths remains unclear.

The incidence of malignancies in asbestosis with chrysotile exposure: a large Chinese prospective cohort study

Frontiers in Oncology, 2023
BackgroundAsbestos exposure is closely related to the occurrence and development of various malignancies. This prospective cohort study aimed to evaluate the incidence rate and potential risk factors in a cohort of asbestosis patients in China.MethodsThe

Asbestos and insurance interests continue to use discredited scientific argument to sell asbestos and to deny justice to asbestos victims

The Journal of Scientific Practice and Integrity, 2019
Chrysotile asbestos represents ninety-five percent of all asbestos sold over the past century. For more than two decades the global asbestos trade has consisted entirely of chrysotile asbestos.

Carbonation of Chrysotile under Subduction Conditions

Engineering, 2019
In order to understand the role of serpentine minerals in the global carbon cycle, high-pressure X-ray diffraction (XRD) experiments were performed on chrysotile (Mg3Si2O5(OH)4) using carbon dioxide (CO2) as a pressure medium.

ROS-mediated genotoxicity of asbestos-cement in mammalian lung cells in vitro

Particle and Fibre Toxicology, 2005
Asbestos is a known carcinogen and co-carcinogen. It is a persisting risk in our daily life due to its use in building material as asbestos-cement powder.
