摘要：Rapid urbanization has lead to increase in the vehicular emissions into the atmosphere and deterioratingthe ambient air quality. This paper focuses on the effects of industrial as well as vehicular emissions along the highwaypassing through the industrial area of Mysore city, India. Results of windrose plots indicate that, wind directionsgradually changed from North-East to South-West from December, 2014 to July, 2015. During winter, windpredominantly blows towards the residential layouts in the outskirts of Mysuru City, however, during pre-monsoon andmonsoon period wind blows away from the residential layout. During the study period results of ambient air qualitymonitored data for SO2, NOX and PM2.5 were found to be well below the NAAQ Standards. PM10 concentration wasexceeding the NAAQ Standards at Location 2 during winter and pre-monsoon seasons found to be 140 μg/m³ and 165μg/m³, respectively. During pre-monsoon, winter and monsoon period the vehicular traffic count along the highwayfound to be 26,526, 24,491 and 24,441, respectively. CALINE4 Model, marginally over-predicts the PM10concentrations with the monitored data and under-predicts the NOX concentration. Sensitivity analysis of the CALINE4Model showed, when wind velocity is less than 2 m/sec PM10 concentration was found to be 169 μg/m³ which is greaterthan the NAAQ Standards.
