      abstract     = {Trace elements contribute typically only a few percent to
                      the total mass of air pollutants, however, they canaffect
                      the environment in significant ways, especially those that
                      are toxic. Furthermore, they are advantageouswith respect to
                      a refinement of source apportionment when measured with high
                      time resolution and appropriatesize segregation. This
                      approach is especially advantageous in an urban environment
                      with numerous time-variantemission sources distributed
                      across a relatively narrow space, as is typically the
                      setting of a megacity.Two 1-month long field campaigns took
                      place in the framework of the Megapoli project in Paris,
                      France, in thesummer of 2009 and in the winter of 2010.
                      Rotating drum impactors (RDI) were operated at two sites in
                      eachcampaign, one urban, the other one suburban. The RDI
                      segregated the aerosols into three size ranges
                      (PM10-2.5,PM2.5-1 and PM1-0.1) and sampled with 2-hour time
                      resolution. The samples were analyzed with
                      synchrotronradiation induced X-ray fluorescence spectrometry
                      (SR-XRF) at the synchrotron facilities of Paul
                      ScherrerInstitute (SLS) and Deutsches Elektronen-Synchrotron
                      (HASYLAB), where a broad range of elements (Na, Mg,Al, Si,
                      P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Se, Sr, Zr,
                      Cd, Sn, Sb, Ba, Pb) was analyzed for each sizerange.Time
                      series of the analyzed elements for the different sites and
                      campaigns were prepared to characterize theaerosol trace
                      element composition and temporal behavior for the different
                      weather situations and urban environments.They allow for the
                      distinction of regional vs. local sources and transport, and
                      provide a basis for sourceapportionment calculations. Local
                      and regional contributions of traffic, including
                      re-suspension, break wear andexhaust, wood burning, marine
                      and other sources will be discussed. Indications of
                      long-range transport fromPolish coal emissions in the city
                      center of Paris were also found.},
