Objective To establish a well controlled laboratorial microbial aerosol generation system for evaluating the efficiency of bioaerosol samplers properly.

Study on median diameters and size distributions of airborne microbes in three functional regions in Beijing;

Research on airborne microbes over some areas of the East China Sea and the Yellow Sea;

Soil,water,animal feeding,fermentation course and rural activity are the important sources of airborne microbes.

By researching the airborne particulates and airborne microbes of different forest type in Yuan Dynasty capital city wall relics park and its' adjacent roads,the results indicated that the proportion of particulates whose diameters were bigger than 10?μm was low in the airborne particulates,but the respirable particulates PM_(10) was relatively higher,whereas the PM_(2.

ObjectiveTo explore the pollution of airborne microbe around key traffic route in Guangzhou urban districts, the study on airborne microbe can be used for the research of health prevention and environment control measures in Guangzhou.

LanZhou air quality to be indicated by the particlesubsiding volume of air microorganism;

The article,by taking samples from 15 monitoring points in 8 activity areas(functional districts) on Northwest Normal University campus and analyzing them,examines the air microorganism and monitors the roads,green land and roads around during the daytime for 16 hours.

After primarily determined on air microorganism in tulupan city, the results show that concentration of average bacterium(B), fungus(F), total bacterium(T) in outdoors and F/T% is 33 106.
