Development of Analytical Techniques for Trace Quantitation of Atmospheric Analytes in Remote and Indoor Atmospheres
Trevor VandenBoer
Visiting Professor
Dept of Chemistry
York University
Abstract: Reactive nitrogen plays key roles in atmospheric chemistry, catalyzing the production of ozone
and formation of new particles from volatile precursors. Emissions of reactive nitrogen from the combustion of fossil fuels and inefficient use of agricultural fertilizers has resulted in a modern world with reactive nitrogen levels never seen before. Its
transport to sensitive and remote ecosystems can result in increased primary productivity or deleterious effects where nitrogen saturation occurs. Quantitative collection and speciation of reactive nitrogen in remote locations poses analytical challenges from
sampling through quantitative and speciated detection. The development of custom off-grid sampling equipment and extensive quality control practices allowed us to capture reactive nitrogen biogeochemical inputs from wet and dry deposition processes at the
atmosphere-biosphere interface across four field sites in the Newfoundland and Labrador Boreal Ecosystem Latitudinal Transect from 2013-2017. The indoor atmosphere poses different yet similar analytical challenges with needs to measure many of the same reactive
nitrogen species in order to characterize relevant chemical processes. Recent developments in reactive-nitrogen instrumentation and measurement techniques by our research group will be presented.
Dr. Trevor VandenBoer is currently a Visiting Professor and Adjunct Faculty member of the Department of Chemistry at York University. He is investigating reactive nitrogen atmospheric
chemistry with the Atmospheric Chemistry Laboratory and is funded by the Alfred P Sloan Foundation to develop new analytical techniques for measuring reactive nitrogen as part of the Chemistry of the Indoor Environment program. He completed a combined Honours
Bachelor of Science degree in Analytical Chemistry and Forensic Science from Laurentian University in 2007. He has subsequently completed an MSc (2008) and PhD (2012) in Environmental and Atmospheric Chemistry with Dr. Jennifer Murphy from the University of
Toronto. He held a Banting Postdoctoral Fellowship with Dr. Susan Ziegler at Memorial University in St. John’s, Newfoundland. Trevor’s ongoing research examines the biogeochemical interactions of nitrogen between the biosphere and the atmosphere. Trevor has
previously received funding from the Harris Centre at Memorial University, the Newfoundland and Labrador Department of Forestry & Agrifoods Centre for Forestry Science and Innovation, and the Canadian Forestry Service.
