Special session #1

Atmospheric Aerosol Processes in a Developed Mega-City: The REPARTEE Study in London.

For more information
please contact:
Roy M. Harrison

 

 

Major air sampling campaigns took place in London in 2006 and 2007 as part of the REPARTEE experiment. Measurements were made at urban roadside, urban background (park) ground-level locations and 175 metres aloft on a tower. Extensive aerosol characterisation took place including traditional measurements of size distribution and chemical composition, but also involving the use of three types of aerosol mass spectrometer. The results are interpreted in terms of aerosol processes occurring in the urban atmosphere.

 

 

 

 

Special session #2

Modelling of Nanoparticle Formation in Industrial-Scale Reactors
Cancelled

For more information
please contact:
Frank Einar Kruis

 

 

The modelling of the synthesis of nanoparticles as well as the unwanted formation in high-temperature downstream processes is of major importance for the understanding and control of nanoparticle size and properties. It is essential to account for nonuniformities in the reactor volume as well as concurrent mechanisms taking place. Realistic models require advanced techniques such as PDF-modelling, DNS, kinetic Monte-Carlo techniques or CFD solvers with integrated particle dynamics models. This special session deals both with industrial-scale reactors as well as lab-scale prototypes intended to study industrial-scale reactors.


 

 

 

 

Special session #3

Aerosol Sampling and Aerosol Analytics

For more information
please contact:
Yoshi Iinuna

 

 

Recent advances in aerosol sampling and analytical techniques have enabled us to obtain highly time and size resolved physical and chemical characteristics of aerosols. Such characterisation is an essential step towards better understanding of sources and processing of atmospheric aerosols. This session aims to focus on the latest development and application of sampling techniques and analytical methods for better characterisation of atmospheric aerosols. Sampling and analytical artefacts are also discussed. Particular emphasis is put on organic aerosols.

 

 

 

 

Special session #4

Atmospheric Aerosol in the Polar Regions. Origin, Properties and Impact on Regional and Global Climate

For more information
please contact:
Kostas Eleftheriadis

 

 

Aerosol characterization in the remote troposphere is of high importance due to the direct and indirect effects of aerosol parameters on climate. The physicochemical mechanisms governing atmospheric processing of particles, new particle formation, as well as interactions with climatic feedback are only partly understood. Over the last years intensive efforts have been undertaken towards achieving these goals, while many projects were realized as part of the Recent International Polar Year Programme (2007-2008). As new results from the IPY projects are still in the pipeline, this session with fresh results from Aerosol Research in the Polar Regions may become a forum for interesting discussions.

 

 

 

 

Special session #5

Special EUCAARI Session

For more information
please contact:
Urs Baltensperger

 

 

This sessions deals with results obtained in the framework of the EC project EUCAARI (European Integrated project on Aerosol Cloud Climate and Air Quality Interactions). The objectives of EUCAARI are:
(I) Reduction of the current uncertainty of the impact of aerosol particles on climate by 50% and quantification of the relationship between anthropogenic aerosol particles and regional air quality, and
(II) Quantification of the side effects of European air quality directives on global and regional climate, and provide tools for future quantifications for different stakeholders.

 

 

 

 

Special session #6

Upscaling and Downscaling in aerosol Process Modelling

Cancelled

For more information
please contact:
Elisabetta Vignati
or
Sabine Wurzler

 

 

The aim of the session is discussing multi-scale aerosol process studies. Size and time resolutions in models have an important impact on the results; understanding of model scale effects on processes and development of particle properties are essential for the correct handling and interpretation of model applications and results.

 

 

 

 

Special session #7

Test Materials in Toxicological and Health Effect Studies

For more information
please contact:
Michael Riediker

 

 

Understanding the health hazards of nanomaterials is very important for a good risk assessment of products containing nanomaterials. However, many methodological questions need to be solved if one wants to obtain reliable toxicological and health effect data. Consequently, this session invites presentations about methodological aspects when using nanomaterials in toxicological and health effect studies. These include safe handling protocols, nanoobject dispersion in media, characterisation of nanomaterials in complex matrices, interferences of nanomaterials with measurement methods, and strategies to compare material data between studies.

 

 

 

 

Special session #8

Artifacts in Measuring PM

For more information
please contact:
Harry ten Brink

 

 

The basis for PM10-measurements is sampling with the obligatory quartz fibre filters and weighing. Very recently it was found that water-vapour is retained in the filters after these sampled at high relative humidities. This leads to appreciable overestimation of PM10-mass. Experts will present their latest results on this artifact. Also, adsorption of volatile carbon-compounds occurs. This adsorption depends on the brand of filter and the pre-conditioning applied.
For measuring PM2.5 the new EU-guideline allows use of glass-fibre filters. We are anxious too hear about adsorption artefacts with this notorious filter material. The new legislation also requires measurement of the composition of PM2.5. The possible necessity of longer-term storage of filters may lead to artefacts such as loss of components by bacterial activity.
The EU-guidelines allow the use of “equivalent” automated instrumentation. Instruments may suffer from their own artifacts.
We look forward to contributions in any of the mentioned fields.
