Crystalline silica is harmful when respirable-sized dust of less than 10 microns is breathed deep into the lungs, as this can cause lung scarring known as silicosis. The lungs become less flexible, making it difficult to breathe and do hard work. The fibrosis of the lungs and the associated inflammation may lead to lung cancer.
