Air pollution is defined as the presence of dangerous or excessive amounts of pollutants in the Earth's atmosphere. These compounds, known as pollutants, can be naturally occurring or man-made, and they can harm human health, the environment, and the climate. There are many different sources of air pollution, including industrial operations, vehicular emissions, etc. Particulate Matter (PM), carbon monoxide (CO), Nitrogen oxides (NOx), Sulphur oxides (SOx), volatile organic compounds (VOCs), and Ozone (O3) are examples of common pollutants. Tirupati which is a pilgrimage city along with its increasing population these two substantial increases in levels of pollution in the air. Four sampling sites are selected for analysis, i.e. Regional Science Centre, Municipal Office, Tirupati, APPCB, RO, Tirupati, S.V.U Guest House, Tirupati. The pollutants data were obtained from the APPCB Office and the pollutants were analyzed through a Respirable Dust Sampler (RDS). This study quantifies various pollutants and Particulate Matter concentrations present in Tirupati city which also focuses upon in and around the city. In the present work, four regions were selected that specify the variations. Here, PM concentrations according to different seasons i.e. Summer (April-June), Monsoon (August and September), and Winter (December to February) are discussed. Results are based on reports of two years 2021-22. The importance of this work is to summarise the data on Air pollution in Tirupati city, which is also one of the world's biggest pilgrimage sites.
