A fuel distillate blend and a heavy distillate cut from SRC-II and a Paraho shale oil were chemically fractionated by Sephadex LH-20 chromatograhy, TLC and HPLC. Fractions were assayed for mutagenic activity by the Ames assay using Salmonella typhimurium TA98 with S9 and MFAO as metabolic activators. Fractions exhibiting mutagenic activity were characterized by GC-MS. The unfractionated Paraho shale oil was least mutagenic followed by the distillate blend and finally the heavy distillate cut. After Sephadex LH-20 chromatography, non-polar mutagens could not be detected in any of the synfuel samples; moderately polar mutagens made a small contribution to the samples total mutagenicity; most of the mutagenic activity appeared to be due to polar mutagens. After HPLC fractionation, the distillate blend exhibited non-polar mutagenic activity. The shale oil's mutagens ranged from moderately polar to polar. In contrast, the mutagens of the distillate blend and the heavy distillate cut were almost exclusively moderately polar. On the basis of the Ames assay with MFAO and the GC-MS analyses, primary aromatic amines appear to play a central role in the mutagenicity of the coal liquids. In contrast, amines do not appear to contribute as much to the activity of shale oil.
