Abstract—We used observational data and numerical simulation technology for evaluating the rate at which that key polluters contribute to air pollutants in the Huancui district of the city of Weihai, China. We evaluated air quality monitoring data, meteorological data, high-altitude sounding data and the emissions intensity of key polluters as provided by the Shandong Provincial Department of Environmental Protection. We adopted the Aermod System, an atmospheric environmental impact assessment system, to simulate pollutant concentrations released from key polluters at each monitoring point in Weihai. Then, we compared the results with values from each monitoring point established by the Department of Environmental Protection of Shandong Province. The results showed the rates that key polluters contribute to air pollutants in the city of Weihai. The analysis concluded that contribution rates of sulphur dioxide and nitrogen oxides from key polluters in the Huancui district of Weihai were higher in the Huaxia Technical School zone at 32.72% and 81.39%, respectively, while they were lower for the remaining five monitoring sites. This study provides data support for the relevant government departments alongside a simple and convinient method to use for related research by using existing official monitoring statistics.

Index Terms—Contribution rate, nitrogen oxides, sulphur dioxide, numerical simulation.
