Early results from HOMEChem, a collaborative field campaign on indoor chemistry

Seminar Abstract 

In the United States, as well as in most of the developed world, people spend about 90% of their time in indoor environments. Although many research efforts have focused on assessing the presence and quantity of chemical air pollutants that affect the indoor air quality, few comprehensive studies have attempted a deeper exploration into how indoor air chemical compounds may interact and transform throughout a normal day of activities. The HOMEChem (House Observations of Microbial and Environmental Chemistry) study was a month-long collaborative investigation into the chemistry of indoor environments that took place in the summer of 2018 at the University of Texas at Austin’s test house, a three-bedroom, 2-bathroom manufactured home. This study investigated the effects of building occupants and their activities, such as cooking and cleaning, on the chemistry of the gas phase, particle phase, and surfaces in a simulated home environment. This study incorporates state-of the art atmospheric chemistry instrumentation from multiple research groups to build a shared dataset from those measurements. This presentation will focus on size-resolved particulate matter measurements, ranging from 1 to 20,000 nm, as well as black and brown carbon optical absorption measurements.

Marina Vance
Assistant Professor, Mechanical Engineering and Environmental Engineering , University of Colorado Boulder

Dr. Marina Vance is an Assistant Professor in Mechanical Engineering and Environmental Engineering at the University of Colorado Boulder. Her research is focused on applying engineering tools to better understand and minimize human exposure to novel environmental contaminants, especially nanoparticles or ultrafine aerosols, from the use of consumer products and other everyday activities. Before joining CU Boulder, she was the Associate Director of the Virginia Tech Center for Sustainable Nanotechnology (VTSuN) and Deputy Director of the VT National Center for Earth and Environmental Nanotechnology Infrastructure (NanoEarth). Dr. Vance received her Ph.D. in Civil and Environmental Engineering from Virginia Tech in 2012 for studying the release of nanomaterials from the use of everyday consumer products. She received her Bachelor’s and Master’s in Environmental Engineering by the Universidade Federal de Santa Catarina (Brazil).
