This study was aimed at utilizing Geo-information technology in assessing the ambient air
quality along some busy roads in urban Zaria. Samples were collected from ten (10) different
sites. Parameters measured include: PM10, CO, NO2 and NH3 were measured in this study.
Also included were: temperature, humidity and traffic volume/composition. The results
displayed in a hazard map indicates that the concentrations of pollutants measured at all
sampling points, with exception of the control site were within and above the hazard limits set
by FEPA. This reveals that transport-related pollution in urban Zaria can be potentially
hazardous to health. The main finding of this research is the comparison between spatial and
non-spatial analysis approaches, which indicates that correlation analysis and buffer analysis of
GIS using the concentration levels of detected air pollutants is relative method for assessing the
health effects of air pollution.
