Abstract
A method is provided for rapidly and reliably determining the potential carcinogenic activity of hydrocarbon mixtures which is especially useful for those of petroleum origin. A sample of the mixture is extracted with dimethylsulfoxide (DMSO). An inoculum of Salmonella typhimurium tester strain T98 is incubated in the presence of an aliquot of the extract together with an optimal amount of induced rat liver homogenate S9. The excessive production of revertant colonies is a measure of the mutagenic activity of the oil, and this measure is shown to correlate with dermal carcinogenic activity.
