Abstract
His study examined urban landuses as catalysts to ambient air quality problems in Calabar metropolis, Nigeria. Data on emission level of CO, NO2, SO2, H2S, and SPM2.5 were acquired using Gasman, while point coordinates were collected using Garmin GPSMap 60CSx device. Student's t- test statistics and Analysis of Variance (ANOVA) were employed to test the hypothesis. From findings, the null hypothesis was rejected for all the test parameters (CO, NO2, SO2, H2S, and SPM2.5) because it could not be concluded that the concentration of parameters measured were higher than the FEPA permissible limits for all the parameters. In order to help identify which ones were significantly higher or lower, the column of mean difference and t-value, where the mean difference is on the negative was consulted.
