Air Pollution and Environmental Implications in Kano Metropolis Nigeria

The study employed both quantitative and experimental approaches, CO and CO₂ was sensed and recorded with the aid of Carbon Monoxide Analyzer and Handheld GPS. Four hundred (400) structured questionnaires was administered and Volumetric traffic count was conducted along seven (7) major junctions across the study area. E. View 8 was adopted for the analysis. Carbon Sensing results depict that Fagge local government area recorded the highest out door CO of 012Ppm. On the other hand, Gwale local government is the top indoor carbon emitters with10Ppm. The field survey indicates that types of land uses, densities and nature of socio-economic activities significantly affect both CO and CO₂ in the metropolis. It indicates that Tarauni local Dangi Junction's average daily carbon sensed records is the highest with exactly 19.5 Ppm. Fagge, Dala and Gwale local governments areas precisely record the same of 14 Ppm. The quantitative air quality indicators demonstrate that, the coefficient of determination (R²) reveals that relatively 84% of the changes in the dependent variable (DV) environmental impact was fully captured in the study and therefore changes within the explanatory variables have significant environmental impacts. Traffic count result shows that, Nasarawa local governemnt maintains the most traffic flow with 18957 vehicles records within the study days and the study indicates that interaction of traffic flow in the metropolis significantly increases the air pollution. Recommendation is drawn from the identified issues.
