This paper presents monitoring results of daily brick kiln stack emission and the derived emission factors. Emission of individual air pollutant varied significantly during a firing batch (7 days) and between kilns. Average emission factors per 1,000 bricks were 6.35–12.3 kg of CO, 0.52–5.9 kg of SO
2
and 0.64–1.4 kg of particulate matter (PM). PM emission size distribution in the stack plume was determined using a modified cascade impactor. Obtained emission factors and PM size distribution data were used in simulation study using the Industrial Source Complex Short-Term (ISCST3) dispersion model. The model performance was successfully evaluated for the local conditions using the simultaneous ambient monitoring data in 2006 and 2007. SO
2
was the most critical pollutant, exceeding the hourly National Ambient Air Quality Standards over 63 km
2
out of the 100-km
2
modelled domain in the base case. Impacts of different emission scenarios on the ambient air quality (SO
2
, PM, CO, PM dry deposition flux) were assessed.
