Surface reactivity of amphibole asbestos. A comparison between crocidolite and tremolite [PDF]
, 2017 Among asbestos minerals, fibrous riebeckite (crocidolite) and tremolite share the amphibole structure but largely differ in terms of their iron content and oxidation state. In asbestos toxicology, iron-generated free radicals are largely held as one of

Effects of chrysotile and acid-treated chrysotile on macrophage cultures [PDF]
Occupational and Environmental Medicine, 1971 Beck, E. G., Holt, P. F., and Nasrallah, E. T. (1971). Brit. J. industr. Med., 28, 179-185. Effects of chrysotile and acid-treated chrysotile on macrophage cultures. The addition of chrysotile asbestos to monolayer cultures of peritoneal and alveolar macrophages produces an increase in membrane permeability, as measured by eosin uptake and lactic ...

Cytotoxicity of Heated Chrysotile [PDF]
Environmental 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 ...

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

The Influence of Various Factors on Nanocatalyst Activity during Benzothiophene Hydrogenation
Applied Sciences, 2022 Herein, we disclosed a method of preparing a nanocatalyst containing nickel-cobalt by impregnation in a hydrochloric acid medium. Optimal conditions were established for all stages of nanocatalyst preparation using the method of probabilistic ...
