An Approch on Using Concentration of Air Negative Ion and Oxygen Consumption as Environmental Monitoring Indexe for Evaluation of Indoor / 环境与健康杂志

In this paper,the indoor air quality of several hotelsand dancing halls was evaluated by using of two monitoring indexes.The results showed that the concentration of carbon dioxide of three dancing halls is low before opening,and the oxygen consumption is low too.But after opening an hour,the concentrations of carbon dioxide and carbon monoxide raises with increase of oxygen consumption correlation analysis between the concentration of air-negative ion and the oxygen consumption showed that both is negative correlation,(r=-0.354,P
