DESCRIPTION:Jenna Ditto\, Postdoctoral Fellow\nDepartment of Chemical Engin
 eering and Department of Chemistry\nUniversity of Toronto\n\nPollutant Tra
 nsport Across the Building Envelope: Emissions\, Chemistry\, and Impacts o
 n Indoor and Outdoor Air Quality\n\nAbstract: The transport of pollutants 
 across the building envelope plays a critical role in\ndetermining both in
 door and outdoor air quality. Gas- and aerosol-phase organic compounds of 
 outdoor origin may enter homes through doors\, windows\, and building crac
 ks\, and these intruding species and their chemical transformation product
 s are important to consider for human exposure. Conversely\, organic compo
 unds of indoor origin are vented outdoors\, and contribute to urban air po
 llution. Indoor and outdoor air are fundamentally interconnected and their
  relationship is critical for human and environmental health. However\, we
  still face many uncertainties about the magnitude and nature of these dyn
 amic indoor-outdoor pollutant fluxes\, competing chemical transformations 
 in variable environmental conditions\, and the ultimate fate\nand impacts 
 of these primary emissions and secondary reaction products.\nIn this talk\
 , I will focus on two case studies that explore the interconnection betwee
 n\nindoor and outdoor air systems in terms of primary emissions and second
 ary multiphase\nchemistry. I will discuss the combination of offline and o
 nline mass spectrometry techniques to probe detailed chemical composition 
 and temporal trends in evolving complex mixtures across gas and aerosol ph
 ases\, including: (1) leveraging high resolution tandem mass spectrometry 
 to investigate chemical transformations in aging boreal wildfire smoke and
  implications for outdoor and indoor smoke exposure in downwind communitie
 s\, and (2) integrating high temporal resolution and high chemical resolut
 ion mass spectrometry to understand functionalized emissions from food coo
 king and evaluate their impacts on indoor air and urban outdoor air qualit
 y.\n\nBio: Jenna Ditto is a postdoctoral fellow at the University of Toron
 to\, working jointly in the\nDepartment of Chemical Engineering and the De
 partment of Chemistry. Her research focuses on characterizing the emission
 s and chemical transformations of major sources of indoor air pollutants\,
  including cooking and smoking. She earned her Ph.D. from Yale University 
 in 2020\, where she developed and implemented non-targeted tandem mass spe
 ctrometry methods to investigate the emissions\, transformations\, and pro
 perties of functionalized gas- and aerosolphase organic compounds at a ran
 ge of ambient field sites in the U.S. and Canada.
