Abstract:

During the third CHARE in 1986/1987,microbes in outdoor and indoor air, ice, snow, lake water,virgin soil,offshore seawater and seaweeds were investigated. The results obtained indicate:there were relatively few microbes in the open air of the Great Wall Station, Antarctica, i.e. the quantity of marine microbes was about 148.7 CFU/m 3 and that of terrigenous microbes about 17.9CFU/m 3. Which indicated that the open air was quite clean. Contents of air-bore microbes indoors were much higher than those outdoors and in the field air.The detection rates and amount of mildew were not high. The amounts of air-borne microbes in different areas varied with human activi-ties and environmental parameters. The results presented here suggested tous that we should continuously improve the purity of indoor air in the Great Wall Station. The amounts of microbes from different sources in the Great Wall Station were arranged in order of magnitude, i.e. ice and snow
