This study was aimed at the detection of the Count Medium Diameter (CMD) of airborne bacterial and fungal particles with the Andersen's six-stage viable air-sampler at four sites over Beijing and Tianjin area. The results were as follows: in the first period (1984–1985) the CMDs annual average were 5.6, 6.6, 5.5, 7.1 µm at Xi-Dan, Feng-Tai, Tang-Gu and Huai-Rou respectively. The CMDs annual average of the airborne fungal particles were 3.9 µm at Feng-Tai and Xi-Dan. In the second period (1987–1988), the CMD annual average of airborne bacteria was 7.3, that of airborne fungi was 3.9 µm at Xi-Dan. At Huai-Rou, the CMD of airborne-bacteria was 7.1.
