This study assesses the air quality of some areas in Kano metropolis. It was conducted for a period of two months in 2013 through direct field measurement of gaseous pollutant concentration in ten different locations using mobile gas censors. The air pollutants measured includes carbon monoxide (CO), sulphur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), hydrogen sulphide (H 2 S), methane (CH 4 ) and ammonia (NH 3 ). In some areas, the study indicated higher concentrations of CO, NO 2 and H 2 S above the air quality standard stipulated by the Federal Environmental Protection Agency (FEPA). This implies that, the air quality of the areas is not within the safe limits. Thus, the consequences of the pollutants to public health were discussed. The study recommends the implementation of tighter vehicular emission regulations and provision of more parking spaces along the higher traffic roads of the metropolis, among others.
