Drug and chemical toxicology

Health and ecological effects of adiponitrile.


PMID 15198072

Abstract

Adiponitrile (ADN) has moderate acute toxicity with an oral LD50 in rats of 100 to 500 mg/kg and a 4-hr LC50 in rats of 1.71 mg/L (vapor plus aerosol). ADN produced slight eye but no skin irritation in rabbits. Repeated exposures by inhalation produced changes in the hematologic profile with effects seen at 100 or 300 mg/m3. The hematologic changes were reversible upon cessation of further inhalation exposures. Dogs fed up to 500 ppm (equivalent to 12-15 mg/kg) showed no effects but 1,000 ppm produced vomiting and nausea which limited further testing at that concentration. ADN was not a genetic toxin, developmental toxin, reproductive toxin nor did it produce an increase in tumors in a 2-yr drinking water study in rats. Human experience reports are limited to one accidental poisoning case and a few skin exposures resulting in transient irritation and inflammation. ADN is rapidly absorbed and excreted by mammals, and is metabolized to some extent although unchanged ADN is readily detected in urine, and does not bioaccumulate.
