摘要: 采用平皿沉降法测定了2006年5月—2007年1月葫芦岛市区室内外空气微生物含量。结果表明:市区室外平均空气总菌、细菌和真菌量分别为15 434.0、14 981.9 CFU/m3和452.1 CFU/m3,真菌占总菌量的2.9%,表明空气处于中度微生物污染状态。闹市、交通要道的空气质量一般比近郊、清净处的差;室外空气微生物浓度显示出时间和垂直高度变化的某种特点。室内空气微生物监测结果反映出室内空气质量尚可。建议应进一步采取得力的环境保护措施,切实改善空气环境质量。

Abstract: The indoor and outdoor atmospheric microbe contents from May 2006 to January 2007 were measured by the sedimentation method of plate in urban regions of Huludao,Liaoning province.The results indicate that the total microbe contents,bacteria contents,fungus contents in the whole urban regions are 15434.0,14981.9 CFU/m3 and 452.1 CFU/m3,and the percent of fungus content to the total content is 2.9%.It shows that air quality is middle pollution level of microbe.The air quality in downtown areas or heavy traffic areas is worse than that in outskirts or less populated areas.The outdoor microbe concentrations vary with time and perpendicular heights.According to the indoor microbe contents,the indoor air quality is better.It suggests that appropriate measures should be adopted to improve the air quality.
