Jan 13, 2005· INTRODUCTION. Inhalation of dust containing crystalline silica has long been recognized as a cause of pulmonary fibrosis (silicosis). Measurement of the airborne concentration of respirable crystalline silica (RCS) is required to provide the exposure data, which are essential for the successful implementation of exposure limits and control measures and for a proper assessment of the health risk.
respirable dust sample collected, which may contain both coal and silica dust as well as other minerals. Currently, the two fundamental techniques used for routine estimation of the silica content of a respirable dust sample are X-ray diffraction (XRD) and infrared (IR) absorption analysis.
