| Abstract | With the introduction of the catalyst technique in the 80s and the associated necessity to offer lead free gasoline methyl tertiary butyl ether (MTBE) was added as the anti-knock improver. However, recently MTBE increasingly turns into the focus of interest, because it was found in groundwater in the USA. In concentrations of 30 mug/l MTBE has a strong unpleasant smelling and it is under suspicion to be carcinogenic. It is it prohibited as additive for gasoline in California since 2002. Alternatively ethyl tertiary butyl ether (ETBE) can also be used to increase the anti-knock behaviour. If ETBE is produced from bioethanol, it is indirectly a good application of an oxygen-containing renewable energy source. In France the use of ETBE is already subsidised by tax exemptions. However, only the renewability of a fuel or a fuel's component does not justify the application, because the combustion process can lead to a lot of hazardous components in the exhaust. So the emissions and their effects on human health have to be analysed for renewable fuels as well. In a preliminary study health relevant emissions from the combustion of fuels containing ETBE- were analysed and compared with commercial fuels. Especially the emissions of benzene, toluene, ethyl benzene and xylenes (BTEX) and the mutagenicity and cytotoxicity of the particulate matter and the condensed phase of the exhaust gas were analysed. The investigations were carried out at an Opel gasoline engine. It was fueled with different blends of gasoline/ETBE. The ETBE content varied between 0 and 30%. In the result the emissions of BTEX decrease with increasing ETBE content in the fuel. Comparing ETBE-gasoline with commercial fuels, high emissions of toluene by Optimax(R) and of xylene by DEA gasoline were noticeable. Mutagenicity and cytotoxicity were found to decrease when gasoline is blended with ETBE. Furthermore the mutagenicity of the emissions of Optimax(R) is noticeable lower than of gasoline without ETBE. |
