SILICA EXPOSURE MEASUREMENT IN REAL-TIME FOR

Silica is expressed as a mass concentration of the contents of a total dust sample. To determine the silica content of an aerosol, a sample is weighed and analyzed by a lab to determine what amount of silica is present. If the sample only contains respirable dust, than the silica contained within is respirable silica.
