| Zusammenfassung |
| The Göte–2005 measurement campaign aimed at studying the influence of
the winter thermal inversions on urban air pollution. Elemental speciation
of PM2.5 aerosol particles, collected on Teflon filters at three urban
sites and one rural site in the Göteborg region, was a major part of the
study. Trace element analysis was done by Energy Dispersive X-Ray
Fluorescence (EDXRF) spectrometry and the concentrations of S, Cl, K, Ca,
Ti, V, Mn, Fe, Ni, Cu, Zn, Br and Pb were determined. The elemental content
of the particles, local wind speed and direction, and backward trajectories
were used to investigate possible sources for the pollutants. We concluded
that S, V, Ni, Br, and Pb had their main sources outside the central
Göteborg area, since elevated concentrations of these elements were not
observed during an inversion episode. Sea traffic and harbour activities
were identified, primarily by the S and V content of the particles. This
study showed that the elemental analysis by EDXRF presents valuable
information for tracing the origin of air masses arriving at a measurement
site. |
