Carcinogenicity
A: General Product Information
CRYSTALLINE SILICA: The International Agency for Research on Cancer (IARC) concluded that there was
“sufficient evidence in humans for the carcinogenicity of crystalline silica in the forms of quartz or cristobalite from
occupational sources”, and that there is “sufficient evidence in experimental animals for the carcinogenicity of
quartz and cristobalite.” The overall IARC evaluation was that “crystalline silica inhaled in the form of quartz or
cristobalite from occupational sources is carcinogenic to humans (Group 1).” The IARC evaluation noted that all
“carcinogenicity was not detected in all industrial circumstances studies. Carcinogenicity may be dependent on
inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution
of its polymorphs.”
IARC noted that increased rates of lung cancer were reported among some workers in ore-mines, quarries,
foundries, ceramics, granite and stone cutting industries. The workers in some of these occupational studies were
exposed to other potential respiratory carcinogens such as arsenic, radon, diesel exhaust, polycyclic aromatic
hydrocarbons or cadmium. The IARC reviewed animal studies and concluded that there is sufficient evidence in
experimental animals for the carcinogenicity of quartz.
Silica-crystalline quartz has resulted in liver, blood, and lung tumors in rats by inhalation, intraperitoneal and
intravenous injection, intratrachael, and intrapleural administration.
