Abstract
Air pollution monitoring studies have been proven inevitably important in developing the future roadmaps for sustainable cities and society. In this context, many researchers have reported ambient air quality-based research programs, to get insight into air pollution and associated health issues. With this context, a study was carried out by ambient air quality monitoring program in major urban cities of Gujarat (most economically stable state), India. A total of fifteen years (2004–2018) data were collected in terms of fine particulate matter (PM2.5), coarse particulate matter (PM10), sulfur dioxide (SO2) and nitrogen dioxide (NO2) from Ambient Air Quality Monitoring (NAAQM) program, initiated by Central Pollution Control Board. Results revealed that PM2.5 and PM10 contributed to pollution over the state as compared to SO2 and NO2. The trend showed that PM2.5 and PM10 levels are decreasing as per the National Ambient Air Quality Standards (NAAQS), 2009. On the other side, PM2.5 and PM10 levels are lowered during 2012–2015, but after 2015, increased trends were observed again for these parameters. Overall, the AQI category of particulate matter was observed from satisfactory to moderately polluted. Authors suggest that decision makers and urban planners should investigate the primary sources of particulate matter for better control.
