| Research Abstract |
This study aimed to elucidate the reason why the number of mesothelioma patients with low pulmonary asbestos and nonasbestos mineral fiber concentrations had increased recently. The results of the study suggested that it was derived from not only the clearance of inhaled fibers but also the decrease of cumulative exposure amounts of fibers due to the improvement of working place environments and shortening of exposed years. It would be very important to pay attention to early detection of mesothelioma among workers exposed to relatively small amount of asbestos and to prevent further asbestos exposure in working places.
