Anthracene, fluorene, carbazole, dibenzofuran, and dibenzothiophene are five typical by-products of coal conversion that are potential environmental pollutants. These by-products were radiolabeled to high specific activity and purity by simple tritium exchange and assessed for environmental fate in model laboratory ecosystems. Anthracene and fluorene were biologically converted to hydroxy and keto analogs. Carbazole was N-methylated and N-acetylated. Dibenzothiophene was microsomally oxidized to sulfoxide and sulfone. Dibenzofuran was relatively inert to biodegradation. (1 graph, 15 references, 7 tables)
