This study investigated air pollution high risk zones with hot spot map of air quality status in Abuja, the Federal Capital Territory of Nigeria. The study period was 2013. The research utilized satellite imagery from NigeriaSat-X 2011 with spectral ranges 0.7-0.9 μm, 0.63-0.69 μm and 0.52-0.62 μm of band 2, 3, 4. Using a geographic information system (GIS), the study developed a relationship between air pollutants and the land use/ land cover of Abuja city. These pollutants include carbon (ii) oxide (CO), and sulphur (iv) oxide (SO2), nitrogen (iv) oxide (NO2) and ozone (O3). The concentrations of the pollutants were obtained from satellite sensors for six (6) measuring locations classified into industrial, commercial, residential and traffic point, distributed within the city of Abuja. The results indicated that the most polluted area was identified as Idu. Using statistical analysis, the study also established a relationship between the concentration of air pollutants and the land use/ land cover classification (industrial, commercial, residential and traffic point) for Abuja city. The result obtained from this study provided substantial evidence to suggest a strong link between air pollutants derived from satellite sensor and land use/land cover (LU/LC).
