Abstract: In this study, spatial and temporal distribution of the concentration of gaseous air pollutants (CO, NO2, and SO2 O3) was carried out using ArcGIS in the wet season of 2016. The study was aimed at assessing the pattern of pollutants distribution in the atmosphere using GIS in the study area. Twelve sampling stations were identified, and calibrated air quality meters were used to measure air quality data during the morning, afternoon, and evening hours respectively for five days. The average concentration of the air pollutants in the morning hours ranged from 25.73 to 4.97 ppm for CO, 0.430 to 0.063 ppm for SO2, 0.275 to 0.021 ppm for NO2 and 0.011 to 0.019 ppm for O3, in the afternoon hours from: 0.257 to 0.040 ppm, 0.492 to 0.027 ppm, 27.60 to 9.57 ppm and 0.069 to 0.012 ppm for SO2, NO2, CO and O3 respectively and in the evening hours. The average evening concentrations of the pollutants ranged from 0.497 to 0.087ppm, 0.305 to 0.064 ppm, 32.27 to 4.60ppm and 0.021 to 0.011ppm for SO2, NO2, CO and O3 respectively. However, higher concentrations of the pollutants were mostly observed in the evening period followed by the morning period then the afternoon period. Mapping of different concentration of air pollutants was carried out using kriging and inverse distance weighting type of interpolation method in GIS environment. This study has established that the quality of air in the study area is very poor and polluted with CO, NO2, O3. The deterioration in air quality could be attributed to the heavy presence of industries within the area, high volume of traffic and slow traffic flow experienced in the area and other anthropogenic activities like meat processing using tire in the slaughter area etc. going on within the Trans-Amadi area. Many residents in this area are exposed to dangerous level of air pollution by pollutants such as NO2, SO2, O3 and CO which has a tremendous effect on health.
