摘　　要：The objective of this study was to determine the black carbon concentration in Beijing in 2003.The aerosol properties were measured using an Aethalometer and a tapered element oscillating microbalance(TEOM)on the roof of the Physics Building of Peking University(39.99°N,116.31°E)from July to August 2003 and from November 2003 to January 2004.The average black carbon(BC)concentrations in the summer and winter were 8.80 and 11.4μg/m3,respectively.During winter,two different cyclone cut offs were installed at the inlet of an aethalometer.The BC mass concentration in TSP,PM_(10),and PM_(2.5)were obtained.The results indicated that in winter aerosol,90%of BC exited in PM_(10)and 82.6%of BC exited in PM_(2.5).The BC in PM_(10)accounted for 5.11%of the PM_(10)mass.
