Geostatical Analysis of Pollutant Gases Across Urban Zaria, Nigeria

This study aimed at utilizing Geo-information technology in assessing the ambient air quality along some busy roads around urban Zaria, Nigeria. Concentration level of air pollutants such as: PM, CO, NO2, SO2, H2S, FL and NH3 were determined. Also included were: noise levels, temperature, humidity and traffic count. The results displayed in a hazard map indicated that the concentrations of pollutants measured at all sampling points, with exception of the control site were hazardous. It was within and above the hazard limits set by Federal Environmental Protection Agency (FEPA). This implies that traffic emission within urban Zaria is not within the safe limits, revealing that transport-related pollution in Zaria urban area 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.
