title: Carcinogenicity and polarographic behavior of dibenz[a,h]anthracene, dibenz[a,h]acridine and dibenz[a,h]phenazine.
abstract: In a simultaneous test of carcinogenicity the authors have studied the activities of dibenz-[a,h]anthracene, dibenz[a,h]acridine and dibenz-[a,h]phenazine. These compounds were dispersed in paraffin disks and subcutaneously implanted in rats. Each experimental group consisted of 30 animals. The number of sarcomas induced by the above-mentioned compounds was 20, 5 and 3 respectively. Tumorigenicity of the aza analogues of dibenz[a,h]anthracene was proportional to their electron donation and inversely proportional to their electron acceptance in the performed polarographic test. The authors discuss the possibilities of using polarography as a screening test for the exclusion of carcinogenic polycyclic compounds.
