Abstract

Emission inventories and ISC-Aermod dispersion modeling tool were used to investigate the impacts of particulate matter (PM) emission from off-grid electric power generators used by a textile factory on ambient air quality (AAQ) of the immediate and distant environment of the plant. Information on diesel consumption obtained from the factory was combined with emission factor of diesel powered generators to obtain the emission rates of PM. The emission rates, meteorological parameters, terrain grid and output pathways were inputed into the ISC-Aermod dispersion modeling tool to obtain the ground level concentrations (GLC) of PM. The maximum GLCs were compared with AAQ limit of 250 μg/m3 set for PM by Nigeria’s Federal Ministry of Environment to establish their impacts. Results showed that worst case scenario (WCS) gave PM concentrations of 1.4 – 17.8 μg/m3 and 0.1 – 6.8 μg/m3 for 1-hr and 24-hrs averaging period respectively. The predicted impact using the WCS showed that the ambient PM of the host air shed changed by 0.1 - 1.2% of FMENV standard. It was concluded that emissions from factory would not significantly affect the ambient PM of the host air shed.
