Abstract

ASSESSMENT OF AMBIENT AIR QUALITY IN THE CAMPUS OF UNIVERSITY OF HORTICULTURE AND FORESTRY NAUNI-SOLAN HIMACHAL PRADESH

The present study aims at finding out the seasonal variation of air quality parameter in the campus of University of Horticulture and Forestry, Nauni and calculate the air quality index (AQI) by selecting four sites namely traffic, residential, farming and forest. The air quality parameters under study were TSPM, PM10, NOx, SO2 and VOCs. For all the air pollutants, the maximum concentration was found at traffic area while the minimum concentration was found at forest area. The pollutant concentration was highest at traffic followed by residential, farming and forest sites. Seasonally, the concentration was highest during autumn followed by summer and monsoon. The AQI of the campus ranged from good to moderate. The highest AQI was observed during autumn at traffic site while the lowest AQI was observed during monsoon at forest site. Seasonally, monsoon showed the best air quality while the autumn showed the highest AQI. The AQI of traffic showed a moderate air quality during all the three seasons while the rest of the study areas showed a good air quality. The study revealed that the concentrations of the air quality parameters were within the permissible limits in the University campus. However, the traffic site had the highest concentration of the pollutants and also showed a moderate air quality index
