Benzene health effects: Unanswered questions still not addressed

Data which could have helped answer many of the scientific questions posed in 1983 concerning the carcinogenicity of benzene are not yet available. Since we do not know of any safe level above zero, the problems that have been plaguing the health protection process relative to benzene can perhaps be best resolved by setting current recommended maximum levels of exposure to 0.004 to 0.1 ppm, and, to the extent possible, avoiding any exposure at all to benzene and benzene-containing products.
