Carbon Monoxide as Indoor Pollutant in Kano Metropolis

The level of carbon monoxide concentrations in three different residential areas of Kano municipality has been determined. Health effects of carbon monoxide are not only determined by its pollution level, but the time spent breathing polluted air. Samples of carbon monoxide gas in three different residential districts within the Kano Metropolis; the high (city), medium (Sabon gari) and low (Nassarawa) density residential districts were assessed. The frequency distribution pattern for the gas is skewed towards high frequency of low concentration with a mean and standard deviation of 4.93 ± 3.08μg/m³. Evidence linking high level of indoor carbon monoxide to low birth weight and increase in prenatal deaths necessitates the need to periodically check the levels of the gas within each house hold in the metropolis.
