An Enhanced Environmental Air Pollutant Capacity Calculation Method Considering Air Fluidity

Abstract

The environmental capacity of air pollutants in the region is an important basis for the Government to scientifically formulate the environmental protection policy of the atmosphere. The known SO2, NOx, and primary PM2.5 environmental capacity of the regions has obvious bias compared to real air quality, because the evaluation method used only considered the local air purification capability and neglected the air fluidity. Thus, this paper proposes a method to improve the environmental capacity by using the air cross-border conveying matrix. As influence of the transboundary transmission of atmospheric pollutants is fully taken into account, the obtained environmental capacity is closer to practical situations.
