Indoor
sulphur dioxide concentration in Kano has been attributed to
closed structured building pattern, substandard housing
conditions and use of firewood. Samples of the gas were
measured in the different residential districts within the
Kano Metropolis; the high medium and low density residential
districts. The distribution within the municipality is
skewed towards high frequency of low concentrations with a
mean and standard deviation of 3.92 ± 1.96
μg/m3. The mean concentration
of the gas in some parts of the city like Goron Dutse,
Jakara, K/Mata and Gwale, Fagge, NNDC, Dorayi and Brigade
were 5.01 ± 1.51, 4.94 ±
0.14, 3.53 ± 1.21, 4.55 ±
0.85, 5.18 ± 2.82, 4.86 ±
1.43 3.61 ± 1.6 and 3.21 ± 1.17 μg/m3
respectively. Fagge and Goron Dutse recorded the
highest levels of the gas. The home environment within the
city is poor. Housing conditions are poor and substandard.
Significant portions of the cooking take place in conditions
where much of the air borne effluents are released into the
living area and people in the inner core of the city rely on
gas, wood dung and crop residues for domestic energy.
