摘要：This study compared Carbon Monoxide concentrations in Urban core and Control station in Kaduna Metropolis, Nigeria. USB-CO data loggers were used for data acquisition for a period of one month. 1hour mean of Carbon Monoxide concentrations for Urban core and Control station were subjected to student "t" test to determine any significant difference in Carbon Monoxide concentration between the two sampled sites. Analysis of Variance (ANOVA) test was employed to test the temporal variability in Carbon Monoxide concentrations in the Urban core. The "t" test results showed a significant difference in Carbon Monoxide concentrations, between the Urban core and the Control station. The ANOVA results showed that there is a significant difference in Carbon Monoxide concentrations level between different times of the day. The 1 h mean WHO recommendation for Carbon Monoxide concentration was occasionally exceeded, while the 8 h mean was daily exceeded in the evening periods in Urban core. In the Control station, there was no time both 1 h and 8 h means WHO recommendation were exceeded. These imply that the Rural environment is relatively more livable than the Urban environment in Kaduna metropolis in terms of Carbon Monoxide concentration levels.
