Abstract

The characteristics of different anthropogenic emissions that degrade air quality in the presence of biogenic emissions were studied. The biogenic emissions in combinations with on-road source emissions, non-road source emissions, and point source emissions individually in the Houston-Galveston-Brazoria (HGB) and Dallas-Fort Worth (DFW) areas that are non-compliant with the 2008 8-hr O3NAAQS were investigated. Outputs from Comprehensive air quality model with extensions were analyzed to predict ambient pollutant concentrations of NO, NO2, CO, SO2, O3, and isoprene to determine the impacts of different emission sources on air quality in HGB and DFW areas. NOx and CO emissions were extensive in both areas. NO and NO2 ambient concentrations were more in HGB than in DFW area, while isoprene concentration was reasonably high in HGB than in DFW. CO ambient concentrations were close for both areas and SO2 ambient concentration was higher in HGB compared to DFW. The combination of biogenic and on-road emission sources was expected to produce maximum O3 concentrations. This is an abstract of a paper presented at the 108th AWMA Annual Conference and Exhibition (Raleigh, NC 6/22-25/2015).
