Title Health risk of exposure to non-occupational sources of benzene

Abstract Repeated exposure to high concentrations of benzene is associated with the onset of leukaemia, and benzene is therefore classified as a human carcinogen. However, no case of benzene-induced leukaemia has been confirmed following repeated exposure at work to benzene at concentrations below 100ppm. Benzene also causes depression of blood formation, but again no case of benzene-induced depression of blood formation has been confirmed at below 25 to 30ppm. Benzene causes chromosal aberrations, but there is no evidence to link these with the occurrence of leukaemia. A maximum permissible time weighted average workplace exposure for benzene of 5ppm and an action level of 1.5ppm have been proposed in the EC.
