Nitrogen dioxide (NO2) is the only widely prevalent coloured pollutant in the atmosphere. The assessment of ambient air quality with special reference to NO2 was carried out in this study at the waste dump site in Osisioma Ngwa Local government Area in Nigeria during the morning and Evening hours of the dry season. Average Air Quality Index (AQI) Pollutant values obtained where within the moderate level as values ranged from Umuigwe Station during morning reading as NO2 (0.04) AQI (86.588); Umujima Station {NO2 (0.05) AQI (89.598)}; Niger Stone Station {NO2 (0.08) AQI (89.838)}; Uratta Amaise Station {NO2 (0.06) AQI (86.894)}; Eyimba market {NO2 (0.06) AQI (79.999)}; Owerrita {NO2 (0.04) AQI (12.36)}; Asaema {NO2 (0.04) AQI (81.580)}.
