Stack-collected coal fly ash from western low-sulfur coal was extracted with 60:40 benzene/methanol. This extract was fractionated by preparative-scale high performance liquid chromatography (HPLC) and the mutagenic activity of 14 fractions was evaluated by microbial assay with Salmonella typhimuruim TA1538. A widespread distribution of direct-acting mutagens, which probably includes both mono- and di-nitroaromatics, was detected.
