1、62010年武汉市集中空调通风系统卫生状况分析石斌 陈文革卢冰王怀记(武汉市疾病预防控制中心)摘要目的:了解武汉市公共场所集中空调通风系统污染现况,防控空调污染、疾病传播。方法:分别抽取武汉市7个中心城区(每区抽取宾馆、商场、医院各1家),21家拥有大型集中空调通风系统单位进行检测。每单位抽检5个风口,共检测105个出风口。污染物检测指标为:送风系统可吸入颗粒物(PM10)、细菌总数、β-溶血性链球菌。结果:一、所检105个出风口样品中,可吸入颗粒物(PM10)、细菌总数、β-溶血性链球菌3个指标合格率分别
2、为27.62%、70.48%、92.38%;二、检测结果显示可吸入颗粒物(PM10)超标率:医院高于商场、宾馆。三、2010年结果与2007年结果比较显示,送风系统细菌总数合格率呈升高趋势,而PM10合格率呈下降趋势。结论:自规范实行后,武汉市公共场所集中空调通风系统由于缺乏科学规范的清洗,集中空调卫生状况良莠不齐,污染状况正呈多样化转变。关键词:集中空调通风系统可吸入颗粒物细菌总数AnalyingoftheHygienicSituationofVentilationSystemsofCentralized
