Ethylene oxide is a hazardous air pollutant. Because ethylene oxide is emitted in Texas and has been determined to be a carcinogen, the Texas Commission on Environmental Quality (TCEQ) undertook an inhalation carcinogenic dose-response assessment to derive a toxicity factor for ethylene oxide. An ad hoc committee of the National Academies of Sciences, Engineering, and Medicine will review TCEQ’s Ethylene Oxide Carcinogenic Dose-Response Assessment Development Support Document.
