The study assessed the spatio-temporal and seasonal variation in the concentration of CO, NO2­, SO2 and PM10 in Gboko, Benue State, Nigeria. Data on the air pollutants were collected at four points between 8:00am-10:00am and 3:00pm-5:00pm daily, from 16th January to 24th February (dry season) and 5th June to 14th 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

The mean concentrations of CO, NO2 and SO2 were higher in rainy season, and the mean concentration of PM10 was higher in dry season, with the mean concentrations of NO2, SO2 and PM10 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.
