目的通过介绍室内空气质量在线动态监测系统的组成原理,在奥运前和奥运期间的应用情况,掌握室内空气质量在线动态监测系统对全市72个奥运场馆及训练馆、119个奥运签约饭店共计191个公共场所的室内空气质量进行监测时的运行情况和体现的特点,分析它的不足和优势,从而探索适应奥运期间公共卫生保障工作及适应社会经济和科技发展的卫生监督监测工作模式。方法本文除了介绍室内空气质量在线动态监测系统在奥运保障过程中对各个场馆实时监测,实时得数据,全面掌握室内空气质量情况之外,还与常规室内空气质量监测方法进行比较。结果奥运会之前的试运行期间,某比赛场馆、某酒店出现室内空气质量在线监测系统报警情况,显示为室内甲醛含量超过国家标准值。相关场馆公共卫生保障人员根据甲醛的特性仔细查找原因,采取措施,排除隐患,在奥运会开幕前,各出现报警情况的场馆甲醛含量下降至国家标准值以下。奥运会期间,全市72个奥运场馆及训练馆、119个奥运签约饭店共计191个涉奥场所的192个(国家体育场安装2个)监测探头24h运行,每5min对室内空气质量进行1次监测,至2008年8月24日止,共计监测1001万余个数据。结论空气质量在线动态监测系统为北京奥运会公共卫生保障工作提供了技术支持。在奥运会期间,它一直保持着稳定地运行状态,不间断对各涉奥场所室内空气质量进行在线监测,不仅为卫生行政部门节约了大量的人力和物力成本,同时为公共卫生监督执法开拓了新的工作思路和成功尝试。各场馆在赛程中均实现空气质量零投诉和零污染事件,给各国运动员提供了良好的比赛环境。因受限于经费问题,本次监测系统只能在各涉奥场所最具代表性的位置安装1个监控探头,在一定程度上降低了监测数据的准确性。
Objective To understand the application of indoor dynamic air quality monitoring system during the pre-Olympic Games and during the Olympic Games, and to master the online dynamic monitoring system of indoor air quality in 191 Olympic venues and 72 Olympic venues and training centers in the city and 191 Olympic-signed hotels The indoor air quality in public places to monitor the operation of the performance and characteristics of its analysis of its shortcomings and advantages in order to explore the Olympic Games during the public health security work and adapt to social and economic development and scientific and technological supervision and monitoring of health work mode. Methods In this paper, in addition to the introduction of indoor air quality online dynamic monitoring system during the Olympic Games real-time monitoring of venues, real-time data, a comprehensive grasp of indoor air quality, but also with conventional indoor air quality monitoring methods are compared. Results before the Olympic Games during the trial run, a competition venues, a hotel indoor air quality monitoring system alarm situation appears, the indoor formaldehyde content exceeds the national standard value. Related public health workers in venues according to the characteristics of formaldehyde carefully find out the reasons for taking measures to eliminate hidden dangers, before the opening of the Olympic Games, the situation of each alarm formaldehyde venues decreased to below the national standard. During the Olympic Games, 192 Olympic venues and training halls in the city and 192 Olympic venues in the Olympic Games totaled 192 (two at the national stadium) monitoring probes for 191 operations. The indoor air quality was monitored every 5 minutes until As of August 24, 2008, a total of more than 10.01 million data were monitored. Conclusion The air quality online dynamic monitoring system has provided technical support for the public health security in the Beijing Olympic Games. During the Olympic Games, it has maintained a steady state of operation and conducted continuous on-line monitoring of indoor air quality in all kinds of Olympic venues. This not only saves a great deal of manpower and material costs for the health administrative departments, but also opens up new ground for public health supervision and law enforcement Work ideas and successful attempts. All venues in the race to achieve zero air quality complaints and zero pollution incidents, to provide athletes in all countries a good environment for the competition. Due to the limitation of funding, this monitoring system can only install one monitoring probe at the most representative locations of all the relevant Olympic sites, to a certain extent, reduce the accuracy of the monitoring data.
