Analysis of the mean concentration of air pollutants in different pick in Enugu Urban, Nigeria

This study analysed the mean concentration of vehicular air pollutants of some selected air pollutants which are majorly products of internal combustion in motor vehicles in Enugu urban. The objectives of the study include; to determine the mean concentration of air pollutants in different pick in the study area, to determine the mean concentration in the seasons of the year and to compare air quality index with USEPA standard limit. The methodology of the study was adopted using Ashley Crossman sampling technique. Data collected in this study were analysed using descriptive and inferential statistics. Findings from the study showed that during the rainy season, the highest mean concentration of PM2.5 (186.33 ± 30.7) and PM10 (385.33 ± 55.90) were respectively found at Abakpa junction. The study recommended urgent attention that seeks to minimise the level of emission of pollutants from vehicles in Enugu urban to protect the teeming urban population.
