title: A comparison of the cellular toxicity of exhausts from cars driven on present and future fuels.
abstract: A cellular test system (brown-fat-cell-test) (BFC-test) has been used to evaluate the toxicity of the particulate phase of exhaust emission from vehicles fuelled with gasoline and alcohol-mixed fuels. The results were evaluated by an analysis of variance with multiple contrasts. The exhaust extracts from cars driven on commercially available gasoline were found to be significantly more toxic to the cellular oxygen consumption than a similar extract of exhausts from cars driven on alcohol-mixed fuels. The lowest toxicity was found with extracts from catalyst processed exhausts.
