Bioassay of Coke Oven Coal Tar Carcinogenic Activity.

PB82230236

Publication Date	1982
Personal Author	Bingham, E.
Page Count	12
Abstract	The carcinogenicity of coke oven coal tar was investigated. C3H-mice were treated dermally twice a week with 50 milligrams of various benzo(a)pyrene (50328) (BaP) solutions in toluene, whole coal tar containing different amounts of BaP, the light oil coal tar fraction, or coal tar with the light oil removed. The authors suggest that coal tar contains additional carcinogens whose potency is masked in the presence of high BaP concentrations or that act as carcinogens.
