Abstract
Examination of asbestos fibers by analytical electron microscope enables to distinguish fiber types by morphological, structural and chemical characteristics. An attempt was made to use the ternary diagram of system MgO-total iron+MnO-CaO+Al2O3+Na2O+K2O, for the characterization and identification of asbestos types. The particulate materials present in lungs have been investigated. The results of energy dispersive X-ray analysis for mineral compositions of these particulate materials are comparable to those obtained by X-ray diffraction study on the lung dusts extracted from the same lung tissues.
