Construction Fugitive Dust Pollution and Control in Beijing

A multi-layer coupling model system is developed by co-operated meso-scale meteorological model ARPS and air quality model Models-3.The construction fugitive dust influence on the air quality of January, April,August and October in 2002 of Beijing is simulated,which is based on the detailed emission inventory of Beijing city and provinces nearby.Results suggest that average pollution contribution ratio of the four months is 8.82 %,8.25 %,12.14% and 13.74%,respectively.The control project that reduces the emissions of construction fugitive dust is proposed and the simulation results suggest Beijing' daily average PM₁₀concentra- tion reduce 8.48μg/m³ after the project is carried out.
