AIR QUALITY ASSESSMENT ALONG THE TRANSPORT CORRIDORS OF KADUNA METROPOLIS KADUNA NIGERIA

ABSTRACT In this study an assessment of air quality along the transport corridor of Kaduna metropolis was carried out with significant results. Data for the work were collected using instruments for measuring air quality, that is, commercial samplers. Three gases were actually collected from ten sample locations. The air samples were analysed statistically using the mean of the distribution, and descriptively interpreted. In this study, it was revealed that air quality vary across the sample points, for instance, reference to the grand mean line 0.2221 for SO2 at two major intersection points of Leventis and Stadium varies, higher value in the mornings and lower values in the evenings, above and below the grand mean, respectively. For CO21308 grand mean point,four locations had higher values above the Grand Mean (GM) point and lower values below the grand mean are six locations. For Carbon monoxide levels, seven locations had higher values above the grand mean of 22.25 while three locations had lower values below the grand mean. Therefore, all areas with low level of carbon monoxide and carbon dioxide were associated with thick vegetation as against areas of scanty vegetation with high levels of CO and CO2. It was thus recommended that possible planting of trees and horticultural activities along the transport corridors of Kaduna metropolis should be carried out in order to reduce the presence of pollutants and degraded air.
