Learn about crystalline silica, a natural material found in stone, soil, and sand, and its link to lung cancer. Find out how people are exposed to it, which products contain it, and how to reduce exposures.
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO2, commonly found in nature as quartz. It can be divided into two categories: crystalline and non-crystalline (amorphous), with different crystal structures, properties, and applications.

Learn about crystalline silica, a common mineral found in many materials and products, and its health effects. Find out how OSHA regulates worker exposure to respirable crystalline silica dust in construction, general industry and maritime.
21 Δεκ 2021 · Respirable crystalline silica stimulates (1) release of cytokines and growth factors from macrophages and epithelial cells, (2) release of reactive oxygen and nitrogen intermediates, and (3) oxidative stress in the lungs. All of these pathways contribute to lung disease.
Crystalline silica, commonly known as quartz, is an abundant mineral in rock, sand, and soil. Silica exposure refers to respirable (< 5 μm) and chemically uncombined (free) silica, which is widely known to cause chronic inflammation and fibrosis in the lung and other organs (American Thoracic Society, 1997).
