Raw and hydrotreated product liquids from process demonstration units of experimental ''H-coal'' and ''solvent-refined coal'' processes were examined for acute toxicity monitored as population growth impairment of Tetrahymena exposed to aqueous extracts and for mutagenic activity monitored as revertants of Salmonella exposed to metabolically activated chemical class fractions. With both systems, deleterious effects are generally reduced as the severity of hydrotreatment is increased. The major exception appears to be with the low severity hydrotreated H-coal distillate where mutagenicity in the polyaromatic fraction is slightly enhanced over that of the raw distillate. However, medium to high severity hydrotreatment appears to be an effective means of reducing biological activity monitored presumably by reducing aromaticity and heteroatom content.
