Characteristics of air pollutants at near and far field regions of a national highway located at an industrial complex

The CALPUFF, EPA regulatory model was set up to understand the dynamics of air pollutants at the industrial complex. The predicted PM10, SO2 and NO2 concentrations at NFR and FFR were found to be 32.31 ± 1.56 μg/m3 and 31.35 ± 1.27 μg/m3; 0.37 ± 0.21 μg/m3 and 0.06 ± 0.04 μg/m3; 12.83 ± 6.55 μg/m3 and 4.67 ± 2.77 μg/m3, respectively. The model showed moderate predictions for PM10 (R2 = 0.44-0.52), SO2 (R2 = 0.41-0.51) and NO2 (R2 = 0.45-0.61) concentrations.
