Exposure to benzene can occur through inhalation, ingestion, or skin contact. The most common route of exposure is inhalation of air contaminated with benzene. This can happen in occupational settings, such as in factories that produce or use benzene, as well as in non-occupational settings due to automobile exhaust, cigarette smoke, and emissions from industrial facilities. Drinking contaminated water or eating contaminated food can also lead to benzene exposure.
