- Quinoline is considered likely to be carcinogenic in humans in accordance with proposed EPA carcinogen risk assessment guidelines (U.S. EPA, 1996) on the basis of observations of exposure-related increased incidence of an unusual malignant tumor in multiple strains of rats and mice, multiple experiments using oral, i.p. and s.c. dosing at an early age. This determination is supported by studies that demonstrate that quinoline is genotoxic.
