[Evaluation of acute toxic effect of 3-cyanopyridine]

General acute toxicity, irritating, and allergic effects of 3-cyanpyridine were studied. LD50 after oral administration amounts to 1185 mg/kg of body weight, 3-cyanpyridine is absorbed through the intact skin: administration of 3-cyanpyridine solution into rabbit skin caused death of animals. Histopathologic studies showed reversible liver and kidney injuries after single administration of lethal and sublethal doses. 3-cyanpyridine significantly irritates damaged skin and in a solid state produces an irreversible cornea opacity. Allergic effect was not found.
