U.S. EPA. IRIS Toxicological Review of 2-Hexanone (Interagency Science Discussion Draft). U.S. Environmental Protection Agency, Washington, D.C., 2009.
The draft Toxicological Review of 2-hexanone provides scientific support and rationale for the hazard identification and dose-response assessment pertaining to chronic exposure to 2-hexanone. 2-Hexanone has been used as a solvent for lacquers, ink thinners, nitrocellulose, resins, oils, fats and waxes. The only U.S. producer of 2-hexanone, the Tennessee Eastman Company division of Eastman Kodak, discontinued its production of 2-hexanone in 1979 and sold its remaining reserves by 1981. Exposure to 2-hexanone is most likely to occur from living near or working in plants that make gas from coal, process oil shale, or produce wood pulp. People living near hazardous waste sites with 2-hexanone can also be exposed. This chemical has been found in at least 199 of 1,416 National Priority List Superfund sites identified by the EPA.
This assessment contains [the derivation of a chronic reference dose and a chronic reference concentration, as well as a cancer characterization.
