silica. Silica is a basic component of sand,
quartz, brick clay, granite and numerous
other minerals and rocks. Exposure to
excessive amount of such dust can cause:
Respiratory disease (affecting your ability
to breathe), including chronic bronchitis,
silicosis and pulmonary fibrosis from
exposure to silica. These diseases may be
fatal;
Skin irritation and rash.
Cancer according to NTP* and IARC* */
National Toxicology Program, International
Agency for Research on Cancer.
