Objectives:
The AIRPET project described here (2001-December 2003) addressed some of the important air pollution issues in China's capital Beijing. These include air particulate sampling and analysis, source apportionment, control technology for diesel exhausts and policy recommendations. (1) Aerosol samples for PM2.5 and PM10 were collected in 2001-2003 in Beijing. The samples have been analyzed by techniques including ICP, IC and modified OC/EC. A revised database of all analytical results obtained in this project has been established on the 24-hr average basis. Results of data quality control and experimental uncertainties were reported. A database on routine air quality, meteorological data, and other statistical information has been compiled and updated. (2) The modeling team has performed computation with PMF and CMB8 software. Source apportionment results derived from both models indicate that the major contributors of PM2.5 and PM10 are: fugitive dust, fossil fuel combustion, vehicle exhausts, secondary particulate, biomass burning and some minor industrial sources. In short, we have identified both regional common problems, such as vehicular emissions, particulate of secondary origin and biomass burning, as well as country-specific problems, such as sand storms and fugitive dust that should be addressed to for effective air quality control. (3) The control team mainly focuses on evaluation of oxidation catalyst and catalytic filters for soot and NOx removal from diesel exhausts in both bench-scale and engine tests. Besides, the performance of fuel additive has been evaluated too.
