我国夏热冬冷地区桂林某高校图书馆CO_2分布特征与健康风险评价

CO_2 distribution characteristics and health risk assessment of an university library in Guilin in hot summer and cold winter

CO_2在自然界中广泛存在,且对人体,地球表面温度、湿度有很大影响。当CO_2浓度超过一定范围时,CO_2会对人体有毒害作用。高浓度的CO_2会引发中枢神经系统中毒、机体缺氧等一系列问题。文章对桂林某高校图书馆进行逐天的CO_2浓度以及温、湿度的实地测量,并发放问卷进行调查。通过连续几个月的实测,结合两百多份问卷调查研究,获得了室内CO_2分布特征、室内热湿环境与CO_2分布之间的关系,并对CO_2的健康风险进行评价。

CO2 exists widely in nature and has a great influence on human body,temperature and humidity on the surfaceof the earth.When the concentration of CO2 exceeds a certain range,CO2 will have a toxic effect on the humanbody.High concentration of CO2 can lead to a series of problems,such as the central nervous system poisoning,andthe body＇s anoxia.In this paper,the concentration of CO2 by day and field measurements of temperature and humidityon the Guilin in a university library,and a questionnaire survey.Through several months＇ measurement and more than200 questionnaires,the relationship between indoor CO2 distribution characteristics,indoor thermal humidity environmentand CO2 distribution was obtained,and the health risk of CO2 was evaluated.
