摘要

Before introducing manganese containing additives for Diesel fuel, it is necessary to estimate the manganese concentrations in ambient air which are to be expected and to compare these concentrations with threshold values for possible adverse health effects. A literature search for health effects made by the Fraunhofer Institute (FhG) is integrated as part 2 of this report. The highest concentrations will occur along highways and in street canyons. Therefore, dispersion calculations were made for both situations. For a hypothetical car inventory of 100% Diesel cars as the worst case the manganese concentrations along highways and in street canyons during rush hours will be about a factor of more than 100 lower than the threshold limit value (TLV) for manganese tetroxide. The real manganese concentrations will be a factor of thousand below the TLV of 1 mg Mn/m/sup 3/ because a fraction of 10% of the light duty car inventory is a more realistic assumption for the Diesel car population and because a considerable amount of manganese is retained on the particle filter.
