Abstract
This study was aimed at determine the contribution of motor vehicle emissions along some busy roads in Kaduna metropolis. The Crowcon Tetra III was used to measure the concentrations of air pollutants such as CO, NO2, and SO2. Also Vehicle count was conducted manually to determine the vehicle volumes at the sampling points. The results indicated that the concentrations of CO, NO2, and SO2.measured were ranged 29.1-37.0ppm, 0.03-0.05 and 0.0037-0.051 respectively. With few exceptions, at some sampling points were all above the National Environmental Standards and Regulatory Enforcement Agency (NESREA) recommended safe limits especially during the afternoon-evening periods. Also the level of pollutants across all the sampling points increases with traffic volume. The study therefore established strong statistical evidence that traffic volume affects the pollutants concentrations at all sampling points. This implies that motor vehicle emissions in Kaduna metropolis is not within the safe limits, and that motor traffic-related pollution in Kaduna metropolis is a potential hazard to the environment and human health. It was recommended that, for the benefit of public health and sustainability of the natural functioning of ecosystems motorization growth should be largely checked by environmental regulations. Also construction of inner roads and bridges that would link Kaduna North and South can be valuable to reduce the number of vehicles on major roads, which in turn will help reduce the concentration of pollutants if there are no serious traffic holdups in a particular area at every point in time
