本研究用国产 ANDERSEN 生物粒子采样器测定了京、津3个地点的大气带菌粒子的粒数中值直径。结果表明年平均大气细菌粒子的中值直径北京西单为5.6μm,丰台为6.6μm,天津塘沽海滨为5.5μm;丰台大气真菌粒子的中值直径为3.9μm。
In this study, domestic ANDERSEN bio-particle sampler was used to determine the median particle diameter of airborne particles in three locations in Beijing and Tianjin. The results showed that the median annual diameter of the atmospheric bacteria in Beijing was 5.6μm for Beijing Xitan, 6.6μm for Fengtai and 5.5μm for Tianjin Tanggu Waterfront. The median diameter of Fengtai airborne fungi was 3.9μm.
