Date/Time: Thu Oct 10 2024 at 14:00<br/><br/>Location: Auditorium/Remote<br/><br/>Speaker: Nadine Borduas-Dedekind (UBC)<br/><br/>Title: Introduction to atmospheric chemistry: Which molecules are we breathing and how do they impact air quality and climate?<br/><br/>Abstract: The atmosphere is a fascinating place to observe chemical reactions! There are gas phase reactions governed by radicals and which lead to ozone and smog formation. There are surface reactions on particles, on buildings, and even on your skin! There are aqueous phase reactions in clouds, in rain drops. All these chemical reactions are affected by meteorological conditions where they can be warmed by the sun, stirred by the wind and solvated by water. In this talk, I?ll present an overview of the field of atmospheric chemistry and my group?s most recent contributions to our chemical understanding of the evolution of organic and inorganic molecules travelling through the atmosphere. We?ll talk about how me measure volatile organic compounds in real time with our ?super-nose? instrument the proton-transfer-reaction time-of-flight mass spectrometer, and how we?ve applied this technique to measure unique molecules in the gas phase with impacts on outdoor and indoor air quality. I hope to leave you with a greater appreciation of the air that you breathe and its impact on air quality and climate.
