空气微生物粒子沉降量指示太原空气污染状况

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理编高，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。

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

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.
