空气微生物粒子沉降量指示太原空气污染状况

To Indicate Air Pollution of Taiyuan city using the precipitable amount of Airborne Microbial Particles

用平皿沉降法初步测定了太原的空气微生物粒子沉降量， 结果表明太原空气中的微生物含量编高， 其空气细菌、真菌、总菌含量分别为２４８１９． ９、６２７． ４ 和２５４４７． ３ＣＦＵ／ｍ ３， 空气真菌在空气微立物总量中所占百分比率为２． ４７， 这意味着太原空气污染相当严重、空气质量不佳， 文章分析了造成太原空气微生物含量增高的原因， 提出了减轻空气污染、提高空气质量的一些措施。

The precipitable amount of airborne microbial particles was primarily examined using the method of gravity plate.The analytic results showed that microbial contents are 24819.0,627.4,25447.3 CFU/m 3 respectively,which were on the high level in the out-door airof Taiyuan city. The percentage of airborne fungous content occupied in the total bacterial amount was 2.47.It means that out-door air pollution of Taiyuan was quite severe and the airquality was not good.
