新疆医科大学校区室内空气质量调查

A study on indoor air quality in camcpus Xinjiang Medical University

目的:了解新疆医科大学校区室内空气质量 ,以便采取措施 ,控制室内污染物的浓度。 方法:分别采用日本理研 CO- 87型便携式 CO检测仪、GXC- 30 10型便携式 CO2 红外线分析器和 P- 5型数字粉尘仪器对校内不同类型房屋内 CO、CO2 和可吸入颗粒物 (ZP)浓度进行了测定。结果:居民楼厨房的 CO浓度明显高于室外 (P <0 .0 1) ,以室内标准来衡量 ,厨房 CO超标率最高 ,其次为学生宿舍 ;而各类房屋室内 CO2 浓度都明显高于室外 (P <0 .0 1) ;校区的 IP浓度室外高于室内 (P <0 .0 5 )。 结论:燃料燃烧、通风不良和吸烟是造成室内空气中 CO超标的主要原因 ,人群活动的公共场所和学生宿舍是产生 CO2 的重要场所 ,室内的 IP浓度主要受室外环境的影响。

Objective: To observe the indoor air quality (IAQ) in Xinjiang Medical University,so as to take measures to control the concentration of indoor pollutants. Methods: The concentration of CO,CO\-2and IP(inhalable particles) different types of house in Xinjiang Medical University were detect with CO-87 type portable apparatus of Japan? GXC-3010 type portable CO\-2 infrared ray analyzer and P-5 type digital dust apparatus. Results: The concentration of CO in residential kitchen was siginificantly higher than outdoor (P<0.01),the exceeding CO in kitchen was the highest weighed by the indoor standard,and next was that in dormitory. The indoor concentrations of CO\-2 in all kinds of house are siginificantly higher than outdoor (P<0.01),and the outdoor concentrations of IP in campus are higher than indoor (P<0.05). Conclusions: Fuel burning,bad ventilation with cigarette smoking are the reasons which result in surpassing of CO in houses. The human activities are the important source in public place and dormitory,and the IP of indoor concentration is influenced by the outdoor enviroment.
