The Environmental Protection Agency (EPA) monitors concentrations of air toxins in the US, including particulate matter smaller than 2.5 micrometers (PM2.5). These fine particles are able to enter the lungs and bloodstream, posing a significant health risk. There is also evidence that people of color in the US are at increased risk for adverse health effects due climate change and pollution (see review article: Berberian et al. 2022). Our goal is to create a model that uses 2021 ACS 5-Year Estimates Data Profiles and EPA data to identify tracts likely to be at risk of high PM2.5 levels. This is intended as a screening tool to inform further research on the climate related health risks and pollution sources that are affecting marginalized communities.
