Nowadays, it is observed that urban activities are responsible for increasing levels of pollution. This study presents the status of ambient air quality in the urban area of Latur city. Three monitoring sites were selected in the study region representing residential, commercial, and industrial areas. These sites were chosen according to the guidelines of the Maharashtra Pollution Control Board (MPCB) and the Central Pollution Control Board (CPCB), New Delhi, to ensure proper coverage of the area. Air quality was evaluated by measuring four major air pollutants: SO₂ (oxides of sulfur), NOₓ (oxides of nitrogen), RSPM (repairable suspended particulate matter), and SPM (suspended particulate matter). The assessment was carried out over a period of one year, from January 2025 to December 2025. Monitoring was conducted continuously for two days (48 hours) per week using a Repairable Dust Sampler (RDS) machine. After one year of investigation, the results showed that the concentrations of RSPM and SPM value close to the standards prescribed by the CPCB in residential and commercial, industrial site areas. The levels of NOₓ and SO₂ at all three locations were within the CPCB standards, though comparison among the sites indicated that their concentrations were slightly higher in the Industrial area.
