Local- and regional-scale racial and ethnic disparities in air pollution determined by long-term mobile monitoring

Abstract: Disparity in air pollution exposure arises from variation at multiple spatial scales: along urban-to-rural gradients, between individual cities within a metropolitan region, within individual neighborhoods, and between city blocks. Here, we improve on existing capabilities to systematically compare urban variation at several scales, from hyperlocal (<100 m) to regional (>10 km), and to assess consequences for outdoor air pollution experienced by residents of different races and ethnicities, by creating a… Show more

“…Increasing spatial resolution from the tract to finer scales (i.e., block group, block) generally had only a minor impact on estimated national exposure disparities between groups. Those findings are consistent with a recent mobile-monitoring air pollution study 25 in one US metropolitan region, which reported that between-neighborhood differences (rather than finer between-block differences) in pollution and in segregation were a main contributor to between-group racial/ethnic disparities in exposure.…”

“…(3) The analysis focuses on between-group exposure disparities. Future studies could address these limitations by incorporating other types of air pollution data (e.g., from other empirical statistical models, 13 chemical transport models, 26 reduced complexity models, 27 satellite-based observations, 9 , 28 mobile monitoring, 25 low-cost sensor networks 29 ), accounting for mobility 30 and indoor 31 environments in exposure assessment, and analyzing other spatial scales (e.g., postal codes, parcels, etc. 32 ) and metrics (e.g., within-group disparities, inequality metrics 23 , 33 ).…”

“…Previous work has shown local and regional spatial heterogeneity of air pollutants within urban and often rural industrial regions [23][24][25], pointing out the inadequacy of the sparse monitoring network in the area for determining attainment in a highly heterogeneous region. The US Environmental Protection Agency's (USEPA) current monitoring infrastructure in the region relies largely on three reference-grade monitors in Ohio and West Virginia (blue 'E'symbols, Figure 1).…”
