Facts about Serpentine Rock and Soil Containing Asbestos in California [PDF]
, 2009 Author(s): Frazell, Julie; Elkins, Rachel; O'Geen, Anthony Toby; Reynolds, Robert; Meyers, James | Abstract: Serpentine and related rocks sometimes contain naturally occurring asbestos (NOA). When these rocks break down into soil, the NOA comes with them, and that creates a health hazard. Learn to recognize serpentine soils and keep health risks

Mechanical and Durability Studies on Ficus exasperata Leaf Ash Concrete
Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022 This paper reports the effect of snake grass (SG) fibers in Ficus exasperata Leaf Ash (FELA) concrete. Snake grass fibers of percentages 0.5, 1, 1.5, and 2 were used in this investigation. Tests of compressive strength, split tensile strength, and flexural strength and durability studies of salt resistance, sulphate resistance, and impact energy ...

Fungal diversity is not determined by mineral and chemical differences in serpentine substrates.
PLoS ONE, 2012 The physico-chemical properties of serpentine soils lead to strong selection of plant species. Whereas many studies have described the serpentine flora, little information is available on the fungal communities dwelling in these sites. Asbestos minerals,

Comparative Studies on the Cytotoxicity of Amphibole and Serpentine Asbestos
Environmental Health Perspectives, 1980 The chemical and physical properties of serpentine and amphibole asbestos are considered in the context of their interaction with tissue of the tracheobronchial tree and lungs. In vitro studies in cultures of several types are evaluated and work with the erythrocyte hemolysis system is reviewed.

Chrysotile asbestos treated with phosphoric acid as an adsorbent for ammonia nitrogen
Heliyon, 2020 The purpose of this study was to find an alternative application for chrysotile asbestos, given that there is a complete structure of extraction and production of this class of serpentine minerals, but its use is banned for many applications.

FOREST PHYTOCOENOSES FORMATION ON SERPENTINE DUMPS OF ASBESTOS DEPOSIT, MIDDLE URALS, RUSSIA
, 2022 The mineral deposits’ development is accompanied by significant disturbances of soil and vegetation in large areas. The study of initial stages of disturbed lands natural overgrowing makes it possible to assess patterns of vegetation formation. Forest phytocoenoses formation on serpentine substrates in the Middle Urals, Russia (taiga zone, subzone of ...

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.
