Respirable Crystalline Silica

Respirable Crystalline Silica


Because of the potential health hazard of the crystalline forms of silica in the industrial environment, federal regulations require monitoring the presence of silica forms in the workplace atmospheres and marketed products. The inhalation of dust as a primary cause of pulmonary disease has been a problem in the mining industry since antiquity.

X-ray powder diffraction is one of the most sensitive methods for the analysis of crystalline forms of silica. In addition to detection and quantification, it can determine the specific crystalline species in the sample. The X-ray diffraction patterns of quartz and cristobalite are distinct from each other and from other minerals with which they may be associated. Most hazard labels are required for products that contain more than 0.1% wt. crystalline silica.|

Analysis procedures of legal standing for the determination of respirable crystalline silica contained in bulk material and air filter samples are primarily designed by governmental safety and health agencies to meet the requirements of federal health regulations. In the United States, the principal organizations are the Occupational Safety and Health Administration, OSHA, and the National Institute for Occupational Safety and Health, NIOSH.
