Abstract
Issues related to sampler selection for dust monitoring in mining were reviewed. Specific topics included the evolution of a dust standard, definition of respirable dust, recent developments in the respirable dust definition, deposition or penetration, sampling and analysis for crystalline silica (14808607), mixed dust exposures and radon (10043922), exposure sampling strategies, compliance sampling strategies in the US, problems with compliance sampling, research exposure sampling strategies, and exposure to dusts containing silica. Questions which need to be addressed in selecting a sampler included whether the effects which will be caused in the alveolar air spaces are calling for respirable dust sampling or are they upper airways problems calling for a thoracic fraction sampler. If the effects are systemic, an inhalable fraction sampler would be more appropriate. The types of chemical analyses required on the sample once it is collected must also be collected. Sample tampering and the quality of historical mine dust exposure estimates were considered.
