Community District Pollution Charts
The charts below summarize the range of estimated wintertime average concentrations for each pollutant (PM2.5, EC, NO, NO2,O3, SO2) across the area within each residential community district. Further information on how monitoring data is used to generate estimates is provided within the methods section of the report. Importantly, concentrations of all pollutants vary within each community district.
