Ultrafine Particles in Urban Areas is an initiative dedicated to the research of the smallest airborne particles that can be found in urban atmospheres.

+++ Düsseldorf Workshop in March 2013 +++

A scientific workshop will be held in Düsseldorf on February 26 and 27, 2013.

Please click here to download a draft of the position paper "Ambient ultrafine particles – what are the current perspectives to elucidate health effects and include these particles in legal regulations?". We plan to finalise this document on the Düsseldorf workshop, and submit it as a "perspective paper" for publication.

Some scientific questions

  • UFPs - how can we measure and/or simulate their spatial and temporal distribution in a complex city?
  • Which are the sources of UFPs in urban areas, and how can the emission/production rates of these sources be quantified?
  • UFPs - do they differ from larger particles with respect to chemical composition?
  • Can we separate exposure to primary and secondary UFPs?
  • Abatement measures for PM - do they also contribute to reduced exposure of UFPs?
  • How can current frontiers of UFP measurement be overcome?
  • Are contrasts between indoor and outdoor exposure more pronounced for UFPs than for bigger particles?
  • How can personal exposure and "personal dose" be estimated from ambient measurements?
  • What are the designs of future studies to elucidate UFP health effects?
  • Could UFPs ever be a pollution metric to be regulated?

Working groups of the previous workshop in 2011

Health-related studies:

  • Epidemiology: Epidemiological long term studies for UFPs, BC, organic carbon; epidemiological short-term studies using UFP and BC exposure measurements (Coordination: Annette Peters, Kathi Wolf, Josef Cyrys, HMGU)

Connecting dispersion modelling and atmospheric measurements:

  • Particle fluxes: experimental determination; application in urban scale and mesoscale dispersion models (Coordination: Stephan Weber)

Experimental techniques:
