Abstract

The study analysed air quality in Yola Metropolis in relation to vehicular emission. The study combined air quality monitoring and Air Quality Index (AQI) assessments to analyze data on key vehicular pollutants (namely PM2.5, CO, NO2, and SO2) from 13 monitoring locations. First, an attempt was made to clarify daily temporal variation of vehicular pollutant where findings revealed that average pollutants concentration was usually low during the morning hours but experiences rise in the evening. Findings also showed that the overall concentrations of CO, NO2 and PM2.5 have health effects on the public while SO2 was considered satisfactory. Findings also revealed that most of the activity hotspots have high pollutant concentration, hence, the risk of adverse health outcome. In conclusion, high pollutants concentration prevails in most of the activity hotspots of the Metropolis and prolonged exposure to such pollutants possesses health risk. The study therefore recommends the need to introduce stricter emission standards for petrol-vehicles so as to reduce higher emissions; moderating automobile dependency and prioritizing HOVs to alternate the low carrying capacity public transports; need to consider active transport by engendering a walkable environment; supporting tree planting programs in the Metropolis among others things.
