TS 7. Chemistry of Secondary Aerosol Formation

Presented By: Paul J. Ziemann

Location: Ruidoso/Pecos

Abstract: Secondary aerosol is an important component of atmospheric fine particles that generally consists of organic compounds, sulfates, and nitrates. The processes that lead to the formation of this material are often complex, and can involve gas- and particle-phase chemistry, nucleation, and gas-particle partitioning. In this tutorial I will discuss the major chemical reactions and partitioning processes involved in the formation of secondary organic and inorganic aerosol (with a strong emphasis on organic aerosol) using examples from laboratory and field studies.

Presenter Bio: Paul Ziemann is a Professor in the Department of Chemistry and a Fellow in the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder. He received a doctorate in chemistry from Penn State University and was a postdoctoral researcher in the Particle Technology Laboratory at the University of Minnesota. His research interests include laboratory studies of the kinetics, products, and mechanisms of organic oxidation reactions and their effects on the composition of gases, particles, and surfaces in outdoor and indoor air. He was a recipient of the AAAR Whitby Award in 2001 and served as President of AAAR from 2009–2010.
