The goal of this assessment is to evaluate both carcinogenic and non-cancer toxicity based on the proposed July 1999 Cancer Guidelines and other relevant guidance. This approach will provide a better understanding of the toxicity and will aid in making informed risk-based decisions for protection of human health. This assessment will be provided in the form of a Toxicological Review and IRIS summary sheets in the IRIS Database. Please refer to IRISTrack - 1,2-Dichlorobenzene, IRISTrack - 1,3-Dichlorobenzene, and IRISTrack - 1,4-Dichlorobenzene for the latest schedule updates.
Dichlorobenzene (DCB) was first evaluated by the Environmental Criteria and Assessment Office (ECAO), Office of Research and Development (ORD), Cincinnati, OH in 1987 for non-cancer and cancer endpoints. It was also evaluated by IRIS in 1996 (inhalation RfC; 1,4-DCB), 1992, 1990 (carcinogenicity and oral RfD respectively; 1,3-DCB), and 1991 (carcinogenicity and oral RfD; 1,2-DCB).
