Silica is a common naturally occurring mineral, also known as silicon dioxide. Silica can be found or manufactured in different forms, broadly divided into crystalline and non-crystalline (amorphous). The most common form of silica is quartz. Silica is found in some stones, rocks, sand, gravel and clay. Silica dust can also be found in: concrete.

Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen. There is no cure for silicosis. Silicosis typically occurs after 15–20 years of occupational exposure ...

Silica dust is made up of small particles that can become airborne during work activities with materials that contain silica. Particles that are small enough to be inhaled deep into the lungs are called respirable. The most common form of crystalline silica is quartz. However, it can also occur in the form of cristobalite and tridymite.
