How did so-called lockdown or stay-at-home orders designed to slow the spread of the coronavirus impact air pollutant concentrations, particularly in underserved communities? That's the question Davyda Hammond, Ph.D., ORAU environmental engineer, and researchers at the University of Houston Air Quality Forecasting and Modeling Lab are working to answer. They are investigating and characterizing the human health risk disparities due to air pollutant exposures prior to and during the COVID-19 pandemic. Hammond's research was funded through the ORAU-Directed Research and Development program. In this episode of Further Together, Hammond discusses her research in-depth and talks about next steps for her and the research team.
