Abstract

Abstract Several petroleum crude oils and shale- and coal-derived petroleum substitutes have been fractionated by chemical class and the fractions have been tested for mutagenic activity. Crude petroleum substitutes tend to exhibit greater mutagenicities than do petroleum crude oils but the mutagenicity is reduced to comparable levels in low-boiling distillates and samples which have been hydrotreated. The mutagenicity is caused by alkaline and neutral constituents of the petroleum substitutes, but only neutral constituents for the petroleum crudes. The mutagenic components constitute less than ten per cent of the mass of the samples.
