Dispersion modeling of noxious pollutants from thermal power plants

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.
