中国“极地”号船的空气微生物

Monitoring of Air-borne Microbes of the Chinese Polar Research Vessel“Ji Di”

在“极地”号船于１９８６年１０月～１９８７年５月赴南极暨环球航行的１９９ｄ中，分７次对该船作了空气微生物监测．结果表明，该船舱内空气微生物含量的大体范围是９７．５～４３２３．０ＣＦＵ／ｍ３。平均在１０００ＣＦＵ／ｍ３左右．其分布状况大体上是上层较中、下层的少．霉菌的检出率约４５．７×１０－２．霉菌与微生物总数量约１７．４×１０－２左右．舱内外空气微生物数量变化受制于船只所处地理位置和季节，舱内空气微生物的变化有其特异性．这些结果基本上客观地反映了该船的空气状况．同时，环境洁净程度与人们的主观努力很有关系。“极地”号船尚有改善环境的余地。

During the 199 days of the voyage of R/V“Ji Di”to Antarctica and round the earth from Oct., 1986 to May, 1987, monitoring of air-borne microbe in the vessel was Performed seven times. The results show that the content of air-borne microbe in the vessel ranged roughly from 97. 5-4323. 0 CFU/M3, averaging about 1000CPU/M3. As to the quantitative microbeal distribution,there were fewer microal in the cabins on the upper deck than those on the middle and lower decks, and fewer in the cabins on the upper deck than those on the middel and lower decks,and fewer in the workins rooms than in the cabins. The detection rates of mildew amounted to 45. 7 %and the content of mildew to 17. 4% of the total quantity of the microbe. The numeral change of air-borne microbes inside and outside of the vessel was conditioned by is geogfaphical location and seasons. There was a Particularity of change about the air-borne microbes in the cabins. Meanwhile, the purity of the environment was related to management and People's subjective efforts. So there is still room for“Ji Di”to improve its enviroment.
