Is silica harmful to humans

Silica can be harmful to humans, particularly in its crystalline form, which is associated with respiratory diseases such as silicosis and lung cancer when inhaled in significant amounts over time. Occupational exposure, especially in industries like construction and mining, poses the greatest risk. However, silica in its non-crystalline form, such as in food and some cosmetics, is generally considered safe in typical exposure levels. Always following safety guidelines and regulations can help mitigate risks associated with silica exposure.
