Abstract |
A face mask was fitted with inspiration and expiration valves equipped with filter-frame and micropore filtering membranes (8µm pores). A dust sampler was thus created which was used to measure the gravimetric dust concentration in the laboratory (calcite powder) and in an asbestos mill. The performance of this apparatus was compared with that of a personal dust sampler. The device gave good performance, particularly in the laboratory tests, even for relatively long sampling times. The variability of the results obtained with the two methods fell within an acceptable range (±20%), similar to that observed in repeated tests, especially those carried out in industrial environments. When the mask was used in an asbestos mill, the dust concentration values were slightly lower, probably because the mask selects a finer dust size. It is hoped that this study will be of value in establishing methods for airborne dust measurement on the basis of the real daily or hourly dose inhaled. |
