The research studies have shown that air pollution has been well thought-out as the main warning to health globally. It requests the participation of researchers from time to time to address and revive the problem sincerely. In India concentration of air pollutants has become a serious issue. In most Indian cities, the level of air pollutants is above the prescribed level as per the CPCB. Gwalior City of Madhya Pradesh (India) is at the entrance of speedy urbanisation and industrialisation which causes the worsening air quality of the city. As per the reports of 2015, Gwalior is listed among the top polluted city in India. To address this problem an investigation of air pollutant concentration was carried out at three stations in Gwalior. In this study SO₂, NO₂ and RSPM and SPM were collected over three stations categorised as residential, industrial and commercial and estimation was done by chemical methods. Meteorological parameters like temperature and relative humidity were also recorded during the sampling period. Seasonal variations of these pollutants have been analysed and noted. From the study, the concentrations of the pollutants were observed to be high in summer and winter than in monsoon and post-monsoon seasons. In this study, it was noticed that the RSPM and SPM levels at all selected sites exceed the prescribed limits. While the level of gaseous SO₂ and NO₂ are observed to remain under prescribed limits. The main objective of this study was to know the quality of air in Gwalior and study its health impacts as the city has been selected as one of the hundred Indian cities that can be developed into a smart city under PM Narendra Modi’s flagship Smart Cities Mission.
