IRIS Toxicological Review of 2-Methylnaphthalene (2003, Final)
2-Methylnaphthalene is a polycyclic aromatic hydrocarbon which is a natural component of crude oil and coal, and is found in pyrolysis and combustion products such as cigarette smoke, coal tar residues, and combustion engines. 2-Methylnaphthalene is used in the manufacture of vitamin K and the insecticide carbaryl (1-naphthyl-N-methylcarbamate). Mixtures containing 2-methylnaphthalene are used to formulate various naphthalene derivatives (i.e., chlorinated naphthalenes used as solvents). 2-Methylnaphthalene has been detected at NPL sites. This was the first IRIS health assessment for 2-methylnaphthalene in the IRIS database. The IRIS Program prepared an assessment that incorporated health effects information available for 2-methylnaphthalene, as well as risk assessment methods. The IRIS assessment for 2-methylnaphthalene consists of a Toxicological Review and IRIS Summary. The Toxicological Review is a critical review of the physiochemical and toxicokinetic properties of a chemical; and its toxicity in humans and experimental systems. The assessment presents an oral reference value for the noncancer effects of 2-methylnaphthalene (RfD), and a qualitative cancer assessment. The Toxicological Review and IRIS Summary were subject to internal peer consultation, Agency review, and external scientific peer review. The final product reflects the Agency's opinion on the toxicity of 2-methylnaphthalene.
|April 2003||EPA released the draft report for external peer review|
|December 2003||EPA released the final tox report and summary document and posted these to the IRIS database.|
