Mineral Fibersunderline

The International Environmental Research Foundation is involved in the characterization of mineral particulates by analytical transmission electron microscopy, powder x-ray diffraction and polarized light microscopy. The mineral particulates can occur as bulk powders collected for example chrysotile asbestos at a mine in Asbest City, Urals Region of the Russian Federation or tremolite asbestos from a whitewash used in Metsovo, Greece. Mesothelioma - a rare cancer associated with asbestos exposure - has occurred among the individuals living in homes containing such whitewash. Mineral particulates may also be recovered from the lung parenchyma of an individual exposed to a pathogenic mineral. Crocidolite asbestos fibers were recovered from the lung of a South African miner with a pleural mesothelioma. Airborne particulates can be characterized for type and concentration such as the gypsum fiber found to be airborne near Ground Zero after the collapse of the Twin Towers.
