Chronic effects and carcinogenicity
Silicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis (symptoms include cough, shortness of breath, wheezing, non-specific chest illness, and reduced pulmonary function), exacerbated by smoking; individuals with silicosis are predisposed to develop tuberculosis.
Cancer status: IARC (1997) concludes there is sufficient evidence in humans for carcinogenicity of inhaled crystalline silica from occupational sources (Group 1), noting that carcinogenicity was not detected in all industrial circumstances studied and may depend on characteristics of the crystalline silica or on external factors affecting its biological activity (see IARC Monograph 68, June 1997). NTP classifies respirable crystalline silica as "Known to be a human carcinogen." ACGIH classifies crystalline silica, quartz, as a suspected human carcinogen (A2).

Further information
In 1997, IARC concluded that crystalline silica inhaled from occupational sources can cause lung cancer in humans; however, in making the overall evaluation, IARC noted that carcinogenicity was not detected in all industrial circumstances studied and may be dependent on inherent characteristics of the crystalline silica or on external factors affecting its biological activity or the distribution of its polymorphs (IARC Monographs, Vol. 68, 1997).
In June 2003, SCOEL (the EU Scientific Committee on Occupational Exposure Limits) concluded that the main effect in humans of inhaling respirable crystalline silica dust is silicosis, and that there is sufficient information to conclude that the relative risk of lung cancer is increased in persons with silicosis; therefore, preventing the onset of silicosis will also reduce the cancer risk (SCOEL SUM Doc 94-final, June 2003).
According to the current state of the art, worker protection against silicosis can be consistently assured by respecting the existing regulatory occupational exposure limits. Occupational exposure to respirable dust and respirable crystalline silica should be monitored and controlled. Workers (and your customers or users in the case of resale) should be informed of the potential presence of respirable dust and respirable crystalline silica as well as their potential hazards.
