Air dispersion modeling software was used to estimate the air quality impacts of 3 thermal power plants
located in Pakistan. The real time emission measurements were carried out for a period of 6 months. The
plume concentration for carbon monoxide, oxides of nitrogen, sulfur dioxide, and particulate matter were
calculated with reasonable accuracy over long distances to estimate the incremental contribution of these
power plants to local air quality. Although the annual average concentration increments from the limited
number of power plants studied were relatively small, the long-range transport of emissions of power plants
imposes potentially significant health and environmental impacts
