AERMOD air dispersion modeling and health risks of gas and oil fueled heating plant emissions

A significant part of the population in Serbia relies on central heating systems during winter months, with around fifty plants operation across country. Common fuels used these primarily include fossil such as fuel oil and natural gas. Combustion some leads to emissions air pollutants. This study evaluates impact quality two boilers at Valjevo city (Serbia) plant. Air were measured separately for facility using standard reference methodology. The AERMOD dispersion model was estimate various combination topographical meteorological data set up a receptor grid exposed pollution within 10 km radius It found that resulting distribution concentration gradient pollutant gases particles less inclined towards centre instead spread eastwards into surrounding villages. health risk from boiler shown be significantly higher than caused by gas-fuelled boiler. Nevertheless, calculated carcinogenic non-carcinogenic risks acceptable limits. However, further research is required adequately assess cumulative generated other emitters.
