The holy city of Haridwar is now emerging as a key industrial destination of the north India due to the presence of IIE Haridwar. Due to increased anthropogenic activities like vehicular emissions and industrial discharges in the Haridwar region, air pollution levels has raised greatly. The objectives of the study were (1) to determine the Spatial and seasonal variations of air quality in and around IIE, Haridwar and (2) to find out the Air Pollution Index (API). For this monthly monitoring of pollutant gases (SO₂ and NO₂) and particulate matter (SPM and RSPM) for two years (2012 and 2013) were done at six ambient air quality monitoring locations, one at each land use area (rural/agricultural, urban residential, protected area, industrial and commercial land use). The average SPM, RSPM, SO₂, NO₂ in the study area were found as 86.92 µg/m³, 81.04 µg/m³, 23.23 µg/m³, 24.73 µg/m³, respectively. It was observed that the average SPM levels exceed WHO standard limit of 120 µg/m³ at IIE Haridwar during study period. The average API during study period was 50.14 which indicates light air pollution. Meteorological conditions along with the distance from sources, particularly road transportation play a major role in deciding the ambient air quality over a region.
