ASSESSMENT OF AMBIENT AIR QUALITY INDEX FOR CHIDAMBARAM TOWN IN TAMIL NADU, INDIA | Journal of ....

The significance of seasonal fluctuations in air pollution concentrations in Chidambaram's urban, industrial, commercial, and agricultural regions is investigated in this paper. In Chidambaram, suspended particle matter (SPM), sulphur dioxide (SO2), and nitrogen oxides (NOx) were measured at eight different locations. The current study examines the impact of industry, urbanisation, and vehicular emissions on Chidambaram's ambient air quality. During the sampling time, meteorological factors such as temperature, relative humidity, wind speed, and rainfall were also measured simultaneously. During the months of January to December 2008, eight different pollution-prone areas were purposefully located, and 8 hour samplings were conducted. These contaminants' monthly and seasonal variations have been observed and reported. The annual average and range values were calculated as well. The concentrations of contaminants are higher in the winter than in the summer or monsoon seasons, according to research. The SPM and NOX levels at all of the sites studied in this study exceeded the statutory limits set by the Central Pollution Control Board (CPCB) in New Delhi, India. The air quality index was used to analyse the ambient air in Chidambaram in this study (AQI). This study looked at the 8-hourly average concentrations of three major criterion pollutants, namely suspended particulate matter (SPM), sulphur dioxide (SO2), and nitrogen dioxide (NO2), at eight distinct locations in Chidambaram in 2008.
