Abstract
The use of diesel as fuel by major industries in Ibadan Metropolis to run heavy duty generating set has increased drastically due the sporadic electricity supply by Electricity Distribution Company. The combustion of diesel results in the emission of Criteria Air Pollutants (CAPs), which are hazardous to human health. This study examined the consumption rate of diesel by the minor and major industries in Ibadan Metropolis between 2015 and 2019, while the Air quality implications were compared with the standards. The study was carried out in a three-step process (emission inventory, estimation of the rate of emission and dispersion modelling to predict the ground level concentration of the CAPs) for the industries within the period. The emission rate of for CO, NOx, PM, SOx and VOC is 77.132, 358.053, 25.170, 23.545 and 5.683 g/s, respectively and their corresponding predicted ground level concentration were 984.89, 4571, 321, 297 and 72.6 µg/m3. This research work will proffer information for the government in policy-making as regards the prompt and most effective method to control air pollution in near future for the citizens of Ibadan.Key words: Diesel, combustion, Pollution,Emission, Criteria Air Pollutants, Air quality
