Asbestos textile production linked to malignant peritoneal

Background: Chrysotile had been used in asbestos textile workshops in Southeast China but a clear relation to mesothelioma is lacking. Methods: All patients diagnosed with mesothelioma from 2003 to 2010 at Yuyao People's Hospital were re-evaluated by multiple expert pathologists with immunohistochemistry and asbestos exposure data were collected.

Thermal Modification of Chrysotile Asbestos CORE

Similarly, asbestos toxicity, expressed as fibroblast growth inhibition, was inversely related to the asbestos pretreatment temperature in the following manner, 700C> 2000C>4000C = unexposed fibroblast controls. Pretreatment of chrysotile asbestos to 4000C reduced its adsorptive capacity for bovine serum albumin by 25%.
