Lay Summary (German)

Lead
Feinstaub setzt sich chemisch überwiegend aus organischen und anorganischen Verbindungen zusammen. Daneben enthält er noch Elemente (vor allem Metalle) in Spurenkonzentrationen. Wegen ihrer geringen Konzentrationen braucht es eine hochempfindliche Messmethode zu ihrer präzisen Bestimmung: Röntgenfluoreszenz Spektrometrie mit Synchrotronlicht. Damit wird eine verfeinerte Quellenzuordnung des Feinstaubs für optimierte Reduktionsstrategien bei der Luftreinhaltung ermöglicht.
Lay summary

Unser Ziel ist es, die Quellenzuordnung von Feinstaub mit Hilfe der Spurenstoffe zu verbessern, damit Emissionsreduktionen gezielt und kosteneffizient vorgenommen werden können. Dazu sammeln wir Feinstaub in drei verschiedenen Grössenklassen und mit einer zeitlichen Auflösung von einer bis zwei Stunden. Dadurch werden Tagesgänge von Stoffkonzentrationen erfasst. Feldkampagnen zum Sammeln von Feinstaub werden vor allem in grossen Städten (‚Megacities’, z.B. Paris, Los Angeles, London) durchgeführt, weil dort die Konzentrationen normalerweise höher sind und die Zusammensetzung stark von anthropogenen Aktivitäten (Verkehr, industrielle Prozesse, Gebäudeheizungen) geprägt wird. In diesem Umfeld sind gewisse metallische Spurenelemente verantwortlich für vermehrt auftretende gesundheitliche Belastungen von Bevölkerung und Umwelt. Die chemischen Analysen werden an den Synchrotron-Anlagen des PSI in Villigen und am DESY/HASYLAB in Hamburg durchgeführt.

Abstract

The project aims at identifying possible sources of ambient aerosols in metropolitan environments with the help of trace elements. Methodologically this will be done with current statistical source apportionment methods based on factor analysis, like positive matrix factorization (PMF), and with meteorological trajectory modeling for the verification of possible geographic source areas. The methods will be applied to time series of elemental composition of aerosols sampled with three-stage rotating drum impactors in the field. The samples are subsequently analyzed with synchrotron radiation induced X-ray fluorescence spectrometry (SRXRF) and X-ray absorption near edge structure (XANES) spectrometry. Ambient aerosol composition is still rather poorly explained with respect to its sources. This is in clear contrast to the demand for precise knowledge of aerosol chemical and physical characteristics to develop optimum mitigation strategies to reduce negative environmental or health effects. Trace elements comprise a relatively small amount of the total aerosol mass, however they are very well suited for source attribution. One caveat is, however, their low abundance in ambient air that requires laborious techniques for their quantification.We propose the analysis of ambient aerosol samples collected with time resolutions of 1 - 2 hours and segregated into three different size fractions (aerodynamic diameters 0.1-1, 1-2.5 and 2.5-10 micro-meter). The samples have been collected during integrated field campaigns in Barcelona, Paris, and Los Angeles in 2009 and 2010. A 4-season field campaign will be performed in combination with an aerosol chemical speciation monitor (ACSM) in Zurich in 2011, allowing a comparison of PM1 elemental concentrations. SRXRF measurements shall be performed at different synchrotron beamlines (SLS Villigen, Switzerland; HASYLAB Hamburg, Germany).
