Abstract
The mutagenicity of dichloromethane extracts of diesel participate exhaust, collected while the engine was running at steady state on diesel fuel alone was higher than when 10% ethanol, butanol, and a middle distillate fraction of SRC-II (a solvent refined coal liquid) were added to the fuel (Salmonella strains TA-98 and TA-100). Although the three fuel extenders decreased the specific mutagenicity of the extracts, they increased the amount of particle-associated organic material 2 to 4-fold, resulting in higher estimates of mutagenicity emitted from the exhaust than that calculated for diesel fuel alone. Small increases in total hydrocarbons and carbon monoxide emissions were measured when butanol and SRC-II were added. Particulate emissions were 15% lower for the three fuel extenders compared to diesel fuel alone. The results point to the need for further research using different engine types and simulated urban and highway driving cycles.
