Determinants of Exposure to Respirable Quartz Dust in the Construction Industry

摘要

Because most masonry building materials contain quartz and because these materials are subjected to a variety of treatments during the building process, quartz is encountered every- where in building operations. The level of exposure to respirable quartz has been measured for some highly exposed groups of employees. At 30 construction sites personal air sampling (PAS) measurements of respirable dust and quartz have been performed and 171 samples have been taken.
