Occupational exposure to silica dust and risk of lung cancer: an updated meta-analysis of epidemiological studies

摘要

BackgroundCrystalline silica is considered as one of the most common and serious occupational hazards to workers’ health. Although its association with lung cancer has been studied for many decades, the conclusion remains somewhat controversial. Our objectives are to review and summarize the epidemiological evidence on the relationship between occupational silica exposure and risk of lung cancer and to provide an update on this major occupational health concern.
