Figure 7.

Environmental justice analysis showing mean (yellow diamond) and standard deviation (whiskers) at each site. Site 2 was not included in the PM_2.5 analysis due to the impact of the local restaurant emissions at that site. (a,b) show the lack of correlation between PM_2.5 concentrations and percent of the population who (a) belong to a minority group or (b) are living below the poverty line. (c,d) similarly show the lack of correlation between NO₂ concentrations and the same two socio-economic variables.
