Title of Lecture
Possible links between marine microorganisms, cloud-albedo and sea ice-melt in the Arctic?
Chairs: Astrid Kiendler-Scharr and Urs Baltensperger
Abstract
In the Arctic clouds are very important for determining the melting of the sea ice. Marine gels have been proposed to dominate the available cloud condensation nuclei (CCN) population. But does marine gels predominately control the optical properties of the clouds? Could there be other biological controls on the formation of the cloud over the Arctic sea ice, and if so will biological activity and production of CCN increase or decrease with melting of the ice? To help answering these questions a review of our present knowledge concerning possible links between Arctic marine biology, cloud properties and ice-melt will be given.

Title of Lecture
Toxicology and Risk Assessment of Airborne Nano-sized Particles
Chairs: Denis Boulaud and Ian Colbeck
Abstract
A typical 4-modal ambient particle size distribution contains very little mass in the ultrafine particle (UFP) mode, but by number UFP exceed all other modes. The definition of their size as <100 nm matches that of engineered nanoparticles (NP), and lessons learned from studies with either UFP or NP will both contribute to the understanding of effects and underlying mechanisms of inhaled nano-sized particles. Results of such studies have shown that particle size, size distribution, concentration, composition, diverse particle surface properties (specifically surface reactivity or particle bound ROS), solubility, aggregation/agglomeration, sources, aging can all influence toxicity. Some of these (e.g., mass, number, surface reactivity) serve as dosemetrics which is useful for comparative hazard ranking of UFP from different sources, or for providing mechanistic information.

Title of Lecture
Particulate air pollution in Europe: main drivers and control strategies
Chairs: Sabine Wurzler and Xavier Querol
Abstract
Particulate matter (PM) is one of the most sensitive air pollution issues in the world and in Europe, because of the evident harmful effects of this pollutant on human health. The presentation aims at giving an overview of PM pollution in Europe nowadays and in the future. What are PM pollutions levels and patterns in European countries, their main drivers and the most efficient control strategies that are or should be implemented? Management options investigated in European and national legislations will be discussed and illustrated with modeling and measurement results. Linkages with global scale patterns and with climate change will be considered as well.

Title of Lecture
The potential of aerosol technology for structuring and characterizing multi-scale functional material
Chairs: José Castillo and Mansoo Choi
Abstract
Within a framework of continuous integrated processing of functional nanomaterials, the lecture describes aerosol based chemical, photochemical, thermal and electrical processing steps which are used to structure the building blocks of these materials and to manipulate their physico-chemical surface properties. Interwoven with the discussion on process design are examples of highly sensitive, aerosol based techniques to characterize particle structure as well as the relationship(s) between structure and functionality.

Title of Lecture
Characterization of residential indoor aerosols and their sources
Chairs: Joakim Pagels and Vladimir Zdimal
Abstract
Indoor aerosols are a mix of ambient aerosols that have infiltrated indoors, aerosols emitted indoors and aerosols formed indoors through reactions of precursors emitted both indoors and outdoors. For reasons of energy saving, air exchange rates between the indoor and outdoor environment have considerably decreased over the years. Therefore, indoor related processes such as combustion, cooking, household activities, electrical appliances, biogenic substances, and secondary organic aerosol formation are often the dominant sources of indoor aerosols. Their concentration, size distribution and chemical composition may vary within a wide range, which makes human exposure assessment a sophisticated task.
