Research Abstract

This research has been achieved in order to quantify the long-term trend of the air quality in Beijing, China where the outstanding and historic development has undergone in the past 10 years at the beginning of the 21^<st> century. The average aerosol concentration in Beijing was approximately five times higher than those observed in several other cities in the world. The air quality in Beijing has not been improved during the past 10 years in terms of the aerosol pollution. Many regulations that have been applied to prevent the air quality in Beijing from the air pollution during the Olympic Games 2008 made the larger aerosols that have the particle size larger than 2.5μm reduced 25%, however it didn't work well for the reduction of much smaller aerosols that have the particle size smaller than 2.5μm.
