Human Mobility Disproportionately Extends PM2.5 Emission Exposure for Low Income Populations

Chao Fan, Yu-Heng Chien, Ali Mostafavi

Ambient exposure to fine particulate matters of diameters smaller than 2.5μm (PM2.5) has been identified as one critical cause for respiratory disease. Disparities in exposure to P…
