title: Tumorigenic activity of non-alternant polynuclear aromatic hydrocarbons in newborn mice.
abstract: The tumorigenic activity of benzo[b]fluoranthene, benzo[j]fluoranthene, benzo[k]fluoranthene, and indeno-[1,2,3-cd]pyrene was evaluated in newborn CD-1 mice. The total doses of these non-alternant polycyclic aromatic hydrocarbons employed in this study ranged from 0.5 to 2.1 mumol per mouse. The results of this assay indicate that both benzo[b]fluoranthene and benzo[j]fluoranthene exhibit significant tumorigenic activity. In contrast to these results, neither benzo[k]fluoranthene nor indeno[1,2,3-cd]pyrene were tumorigenic under these assay conditions.
