Definition

Silicosis is a lung disease. It is caused by breathing dust that has crystalline silica in it. In acute silicosis, the disease happens after weeks or months of being around high levels of silica.

Causes

Silica dust can come from cutting, drilling, breaking, or grinding soil, sand, granite, or other items. When the dust gets into the air you breathe, it may become trapped in your lungs. This can harm them and make it hard for you to breathe.
