dc.description.abstractAsbestos is a group of hazardous particles used in construction works due to its fireand water-proof properties. It is often used for thermal insulation, fire proofing, acoustic insulation, roofing, flooring and in a variety of other building materials. The inhalation of asbestos can cause serious health problems like malignant lung cancer, mesothelioma (a formerly rare cancer strongly associated with exposure to amphibole asbestos), and asbestosis (a type of pneumoconiosis) (1). Currently there are several techniques for detecting asbestos: Phase Contrast microscopy (PCM), Polarized light microscopy (PLM), Transmission Electron microscopy (TEM) and Scanning electron microscopy (SEM). PCM is the most commonly used method of imaging asbestos fibers even though it has several disadvantages. The main disadvantage is that PCM cannot distinguish asbestos from other particles (ex: gypsum, mineral wool, fiberglass, cellulose etc.). Secondly, relatively poor resolution of Phase contrast microscopy does not allow imaging of the finest asbestos fibers that may be as small as 0.02 μm in diameter. Thirdly, Phase contrast optics produces halos around particles, in which those halos can be wrongfully distinguished as fibers. Also, the last one is poor contrast between fibers and background.-
