For example, larger particles of dust can be an irritant to the eyes and throat, while smaller respirable dust particles less than 5 microns can be inhaled, deposited in the lung and cause respiratory problems. News · Equipment and Services ·
Respirable crystalline silica is a chemical compound present in stone dust, soil, granite and many other minerals. It has been classified as a human lung carcinogen, which can potentially cause silicosis.
Dust particle size is a key determinant of potential hazard to human health. Particles larger than 10 μm are not breathable, thus can only damage external organs – mostly causing skin and eye irritations, conjunctivitis and enhanced susceptibility to ocular infection.
Dust includes tiny particles of debris and dead skin. Its small size means it can be inhaled and potentially evoke an immune reaction. Such allergic reactions may be minor or major depending on the
The type and size of a dust particle influences how harmful dust is to human health. The possible amount of dust present in the air and how long you have been exposed to it are also important factors. There is stronger evidence of long term health effects from PM2.5 captured particles, which includes ultrafine particles.

Crystalline silica has been classified as a human lung carcinogen. Additionally, breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. The respirable silica dust enters the lungs and causes the formation of scar tissue, thus reducing the lungs’ ability to take in oxygen.
