| Popis: | Airborne soot concentrations in fine dust up to 10 μm mean particle diameter were measured in seven buses and tramways during regular rides in 4 h periods at different daytimes in Munich. With regard to the traffic-related measurements, the main part of particle emissions is caused by motor vehicles. Between March 1995 and July 1996, a total of 105 analyses were accomplished and total as well as elemental carbon were measured. The average value of all measurements amounted to 32.1 μg total carbon/m3 and 14.8 μg C/m3 for elemental carbon. In the mean, 45.2% of the total carbon belonged to the elemental carbon. |
