Air pollution causes about seven million premature deaths globally each year and accounting for 20% death in India, posing a major environmental and public health concern in semi-arid North Indian cities due to industrial activity, vehicle emissions and fast urban growth. This study evaluated the seasonal and spatial variability of PM2.5, PM10, NO2 and SO2 at five representative land-use sites in Rohtak, Haryana, India and integrated pollutant measurements with AQI evaluation and GIS- based spatial mapping. Ambient monitoring was performed with an Ecotech AAS127 sampler for PM2.5 and PM10 Envirotech APM 411High Volume Sampler for samplers for gaseous pollutants. At each site, 24-hour samples were collected every other day in winter (October 2021-February 2022) and summer (April-July 2022).Concentrations of pollutantswere higher duringwinter, with PM2.5 ranging from 72.33-92.76 µg m-³, while lower summer concentrations were observed across sites. Industrial and traffic locations consistently recorded the highest pollutant loads and AQI values (183.80-207.71), whereas control site showed the lowest concentrations. GIS-based AQI mapping showed spatial concentration of poorer air quality in traffic and industry-influenced zones. These findings yield site-specific baseline evidence for seasonal degradation of air quality in a semi-arid Tier-II city and support targeted urban air quality management.
