The effect of chronic ethanol consumption by Syrian golden hamsters (SGH) on the carcinogenicity and target tissue metabolism of N-nitroso-pyrrolidine (NPYR) and N'-nitrosonornicotine (NNN) has been examined. Ethanol-consuming hamsters treated with NPYR developed more nasal cavity and tracheal tumours than controls. Ethanol consumption did not affect the carcino-genicity of NNN. When the metabolism of NPYR and NNN by isolated tracheal rings was examined, it was observed that tracheal rings isolated from ethanol-consuming SGH metabolized NPYR at a higher rate than similar preparations from control animals. In contrast, no differences in the rates of metabolism of NNN were observed.
