Group for Air & Particle Analysis

Airborne pollutants such as aerosols and engineered nanoparticles pose severe threats on human health and the environment. The air quality and particle research group develops novel techniques for the characterization, abatement and remediation of airborne pollutants for a sustainable and responsible technology development. Research topics include and are not limited to the development of novel nanoparticle filtration strategies, simulations of aerosol transport and fate, and laboratory and field measurements of particle emission rates and properties

Main Projects

European Standardization regarding Airborne Nanoparticle Filtration. Filtration is one of the most effective ways of mitigation release of nanoparticles into the environment and exposure to human. Filtration testing for nanoparticles, especially those down to single-digit nanometers, is a challenging task which necessitates generation of a large amount of exceedingly small particles, and accurate sizing and quantification of such particles. Partners of the project include University of Minnesota, USA; Politecnico di Torino, Italy; Camfil Company, Sweden and Unifil Company, Switzerland. (Ph.D.s theses of Y. Bahk, P. Sachinidou, funding: European Commission).

Particulate Matter and Gas Phase Emission Measurement of Aircraft Engine Exhaust. Commercial aviation is a unique source of particulate matter (PM) emissions in the upper troposphere. It also contributes to elevated background PM levels in the urban areas close to airports. Up-to-date emission inventories and physico-chemical characteristics of the PM are needed for the emissions quantification as well as the global and health impact assessments. This project is an international effort to quantify and characterize aircraft PM emissions in an engine test cell at Zurich airport using a standardized sampling system and state-of-the-art instruments. It directly contributes to development of a global certification standard for non-volatile PM emissions from commercial aviation. (Ph.D. thesis of L. Durdina, funding BAZL).

Measuring and controlling coexistent airborne particles and persistent organic pollutants: Gaseous persistent organic pollutants (POPs) are serious concerns for their impacts on the health and environment. These effects can be magnified with the coexistence of aerosol particles, due to the potential absorption and mobility for long-range transport provided by the latter. The aim of this project is to identify and quantify the organic species in gas phase or on aerosol particles with suitable sorbents or with an aerosol collecting instrument (nanoMoudi, etc), from locations with potentially high concentration of POPs and aerosol particles, such as the nanomaterial manufacturers and the exhaust of aircraft engine. With the knowledge of the chemical component/distribution in airborne form, appropriate methods can then be suggested to control and reduce the airborne organic pollutants. (PhD thesis of Y.Y. Kuo).
