Abstract:
The new emission inventories of Beijing city were developed based on the Four Stage Measures of Short-term Air Pollution Control implemented by Beijing municipal government. The concentrations of primary air pollutants SO2, NOx and PM10 in urban area during the time period of the Four Stages were simulated by an air quality model. It was shown that those measures have significant effects on the reductions of emissions and environmental concentrations of SO2 and NOx, while for PM10, the control strategies were not so effective.
