Abstract | Fossil fuel electric generators are known to emit gaseous pollutants that negatively affect the Indoor Air Quality (IAQ). This paper assessed the effects of electric generator use on IAQ by households in Kaduna metropolis of Nigeria. The concentrations of Carbon monoxide (CO), Sulphur dioxide (SO2) and Oxides of Nitrogen (NOx) in the indoor air for fourty eight (48) household, were measured using the IMR 1400C Gas Analyzer. Results indicated mean concentrations of CO, SO2 and NOx within the World Health Organisation (WHO) and Environmental Protection Agency (FEPA) limits (10ppm, 0.01ppm and 0.04 - 0.06ppm) in majority (i.e. 81.25, 83.33 and 85.42%) of the households. However, few (18.57, 16.67 and 14.58%) households' concentrations were significantly high (85.33, 6.99 and 2.99ppm) which are alarming because these involve human lives. Conclusion was reached that about twotenth of the population are at risk of poor IAQ associated with use of fossil fuel generator. |
