摘要：Highway passing through the industrial area of Mysuru constantly experiences emissions from vehiclesand industries situated in close proximity to the highway. Prediction of the seasonal variations on the air pollutantsconcentrations at three receptor locations along the highway contributed from line source; point sources, and combinedline and point sources using CALINE4 and AERMOD air pollutant dispersion models, respectively, have beenstudied.CALINE4 model predicted PM10 concentration was found to be in good agreement when compared withmonitored values showing R2 value of 0.943, whereas, the model marginally underpredicted NOx concentration with R2value of0.901. Further, CALINE4 model was sensitive to changes in wind speed. At location 2, the measuredPM10concentration of 140.5 μg/m3was found to be maximum during summer season, which was mainly due tovehicular emission sources. The AERMOD predicted PM10, NOx and SO2 pollutants concentration emitted from pointsources at different averaging time periods were found to be within the NAAQ Standards. AERMOD was found to beunderpredicted the PM10 concentration contributed from combined point and line sources with R2 value of0.260.Maximum contribution of PM10 and NOxconcentration wasfound to be from vehicular sources when compared toindustrial sources at the receptor locations.
