Analytical and Atmospheric Chemistry
My main research interests are focussed on the study of atmospheric aerosols, their chemical composition (organic and inorganic) and their effects on environment and human health.
Aerosols are suspended particles in air and are ubiquitous. Dependending on the production or formation process aerosols will show different composition and cover different sizes. In fact, the chemical composition of an atmospheric aerosol can tell something about its source and/or travel path. Generally it can be distinguished between natural and anthropogenic (man-made) sources and some elemental species are directly associated to these sources: Al, Si and Fe, for instance, are indicators for wind blown soil dust, and Na and Cl are found in the marine atmosphere as constituent of sea salt. Anthropogenic tracers are: V, Pb and Ni, which are commonly associated with fossil fuel combustion.
We are collecting aerosols with high temporal resolution (1-2 hours) at the "Loyola University Chicago Air Monitoring Station" (LUCAS) and analyze these samples for different species. A procedure for quantification of elemental species has been developed employing total reflection X-ray fluorescence (TXRF. In addition, ionic species are quantified by using ion chromatography. The high time resolution provides us with information about transport patterns of air masses during one day, when considered together with local meteorology. Our measurements and collection station -LUCAS- is located close to Lake Michigan on the Lake Shore Campus of the University. It is equipped, besides the aerosol sampling units, with a meteorological station, an UV photometric spectrometer for ozone analysis and an chemiluminescence analyzer for NO-NO2-NOx analysis.
Field projects our group participated include the Phoenix Sunrise Experiment 2001 and the Chicago Land-Lake Breeze Experiment 2002/2003. Currently we are in the process of analyzing the data obtained at LUCAS during the last five years.
In the future we plan to extend our sampling capabilities and study organic species in particulates as well as health effects related to particulate air pollution.
