4 Average PM Composition: Influence of Site Type

5 Average PM Composition: Carbonaceous Fraction (EC+OM)
of PM10

6 Average PM Composition: Secondary Aerosol
of PM10

7 Change factor for episodes <30 µg/m³  >50 µg/m³
7 Berlin + 3 NRW + 4 R.-P. decrease < prop. increase = prop. increase > prop. increase Episode 2006 B.-W.

8 Outlook: German Contribution (UBA/IUTA)
PM10 gradients rb  ub  hot-spot for major agglomerations in Germany Evaluation of information on mass closure/ compound gradients Results of source apportionment studies THANKS!
