Data on the air pollutants were collected at four points between 8:00am-10:00am and 3:00pm-5:00pm daily, from 16 th January to 24 th February (dry season) and 5 th June to 14 th July (rainy season) in 2017 using Gasman hand-held gas monitors. Data were analysed using mean, coefficient of variation (CV) and Analysis of Variance (ANOVA). The result showed highest and lowest mean concentrations of CO of 21.86ppm (rainy season) and 17.00ppm (dry season) in the town center (Point 2, GBKC) and 2.46ppm (rainy season) and 2.45ppm (dry season) in the suburb (Point 1, YRA). The mean concentrations of CO, NO 2 and SO 2 were higher in rainy season, and the mean concentration of PM 10 was higher in dry season, with the mean concentrations of NO 2 , SO 2 and PM 10 higher than the national acceptable levels in both seasons. The spatial variation in concentration of the air pollutants was significant with respect to land use/land cover types than seasons. There should be regular monitoring of air quality as the population and human activities increase in the town. Keywords air pollution, pollutants, land use/land cover, season, anova 1. Introduction Air pollution, one of the key environmental problems associated with urbanisation (Cho & Choi, 2014), is the first observable and oldest environmental impact on climate by cities (Landsberg, 1981) and is a crucial challenge of the anthropocene threatening the stability of earth systems, thereby driving global climate change, destroying ecosystems and endangering human health (Power et al., 2018). The atmosphere can be regarded as polluted when it contains, to a considerable content, some extraneous 38
