The Toxicological Review concludes that chronic benzene exposure may pose several types of noncancer human health hazards. Hematotoxicity, e.g., progressive deterioration of hematopoietic function, has been consistently reported to be the most sensitive indicator of noncancer toxicity in both experimental animal studies and occupationally exposed humans. The hazards can result from inhalation, oral or dermal exposure, though the exposure circumstances vary. The Toxicological Review includes estimates of chronic exposure levels for oral exposure (RfD) and inhalation exposure (RfC) that are thought to be without appreciable risk.
