About the Seminar:

Between time spent at work, commuting, and in the home, humans spend most of their time indoors. Because of this, indoor air serves as an exposure pathway to a wide range of air pollutants. Indoor environments also have significantly more surface area than outdoor ones which increases the partitioning of molecules into surface reservoirs, even for molecules that would be considered volatile outdoors. Researchers use a variety of techniques to understand indoor air chemistry, resulting in major uncertainty in key chemical and physical properties of indoor spaces and the chemicals that reside in them. As a result, models struggle to accurately predict the chemistry of indoor environments. One route to remedy this is by using stable isotope labelled compounds across volatility-reactivity space as tracers to measure their lifetime and chemical evolution to better understand the chemistry of indoor spaces.
