Commentary on Notification and Recordkeeping of Occupational Mesothelioma in India. [PDF]

open access: yesAm J Ind Med
ABSTRACT In India, some occupational diseases are notifiable under the Mines Act, 1952, and the Factories Act, 1948. Mesothelioma, primarily attributable to asbestos exposure, has been listed specifically as one of the notifiable diseases under the Mines Act, 1952, and is notifiable under the category of occupational cancer in the Factories Act, 1948 ...

Chrysotile, tremolite and fibrogenicity [PDF]

open access: yesThe Annals of Occupational Hygiene, 1999
Abstract Recently published analyses have shown that the risks of mesothelioma and lung cancer in Quebec chrysotile miners and millers were related to estimated level of fibrous tremolite in the mines where they had worked. An analysis has therefore been made of radiographic changes in men who in 1965 were employed by companies in Thetford Mines ...

Tremolite and Mesothelioma [PDF]

open access: yesThe Annals of Occupational Hygiene, 2002
Exposure to chrysotile dust has been associated with the development of mesothelioma and recent studies have implicated contaminating tremolite fibers as the likely etiological factor. Tremolite also contaminates talc, the most common non-asbestos mineral fiber in our control cases.We examined 312 cases of mesothelioma for which fiber burden analyses ...

Surface reactivity of amphibole asbestos. A comparison between crocidolite and tremolite [PDF]

open access: yes, 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

Chrysotile, tremolite and carcinogenicity [PDF]

open access: yesThe Annals of Occupational Hygiene, 1997
It has been suspected for many years that amphibole fibres in the tremolite series, a low level contaminant of chrysotile asbestos, may contribute disproportionately to the incidence of mesothelioma and perhaps other exposure-related cancers. A cohort of some 11,000 Quebec chrysotile workers, 80% of whom have now died, provided the opportunity to ...

Crystal-chemistry and short-range order of fluoro-edenite and fluoro-pargasite: a combined x-ray diffraction and ftir spectroscopic approach [PDF]

open access: yes, 2013
In this study we address the crystal-chemistry of a set of five samples of F-rich amphiboles from the Franklin marble (USA), using a combination of microchemical (EMPA), SREF, and FTIR spectroscopy methods. The EMPA data show that three samples fall into

Surface and bulk modifications of amphibole asbestos in mimicked gamble's solution at acidic PH

open access: yesScientific Reports, 2021
This study aimed at investigating the surface modifications occurring on amphibole asbestos (crocidolite and tremolite) during leaching in a mimicked Gamble’s solution at pH of 4.5 and T = 37 °C, from 1 h up to 720 h.

Carbonate alteration of ophiolitic rocks in the Arabian–Nubian Shield of Egypt: sources and compositions of the carbonating fluid and implications for the formation of Au deposits [PDF]

open access: yes, 2016
Ultramafic portions of ophiolitic fragments in the Arabian–Nubian Shield (ANS) show pervasive carbonate alteration forming various degrees of carbonated serpentinites and listvenitic rocks.
