Abstract: In the present study, ambient air quality of Rohtak city (Haryana) was monitored by High Volume Sampler .The selected parameters to judge the quality of air were Sulphur dioxide (SO2), Nitrogen dioxide NO2), Ozone (O3) and Suspended particulate matters (SPM) which give a fair idea of pollution load carried by the air. The monitoring data were collected from six sites randomly selected in Rohtak city. Sulphur dioxide was found below the permissible limits of National Ambient Avo Quality Standards (NAAQS) at all the sites. Higher concentration of SO2 was observed during winter in comparison to summer and monsoon seasons. Nitrogen dioxide concentration was found to be above the prescribed standards of NAAQS at four sites in winter season. Ozone concentration was found below the prescribed standards (NAAQS), but its concentration was higher in summer season as compared to winter. Suspended particulate matter concentration was observed above the safety limits at all the sites in all three seasons.

Key words: SPM, Sulphur dioxide, Nitrogen dioxide, Ozone
