Comments
Crystalline silica is the most widely occurring of all minerals. The most common form of silica is sand. The International Agency for
Research on Cancer (IARC) has designated crystalline silica in the form of quartz or cristobalite a Group 1 (carcinogenic to
humans). This designation was based on an increased risk of lung cancer among crystalline silica exposed workers. IARC did
note that carcinogenicity of crystalline silica in humans was not detected in all industrial circumstances studied. Further,
carcinogenicity of crystalline silica may be dependent on inherent characteristics of the crystalline silica or external factors affecting
its biological activity or distribution of polymorphs. (IARC Vol. 68, 1997, p. 41). The National Toxicology Program (NTP) classifies
crystalline silica as "reasonably anticipated to cause cancer in humans" (6th Annual Report on Carcinogens, 1991). Long term
inhalation of crystalline silica can also result in the lung disease, silicosis. Symptoms of this disease include coughing and
shortness of breath. (NJ HSFS, January 1996).
Percentages (concentrations) represented as a range are due to batch-to-batch variability. The exact percentage (concentration) of
composition has been withheld as a trade secret.
