通信作业环境空气质量的测定及评价指标相关性

选择计算机终端室，通信机房，通信值班室３个典型作业环境，在设立室外对照点的情况下，现场测定ＣＯ２、ＣＯ、ＩＰ、细菌总数、空气离子、挥发性有机物（ＶＯＣｓ）等１０个指标。结果显示：上述指标在机主主作业环境内均得以检出，其中ＶＯＣｓ浓度较高据日均值和１ｄ的浓度变化趋势，各指标间存在一定的相关性，物品是空气离子与ＣＯ４、ＣＯ、ＶＯＣｓ、细菌总数、ＩＰ等具有正或负的相关性，可作为评价通信作业环境空气质量的

Correlation between Determination of Air Quality and Assessment Indicators in Communication Workshop

Ten indicators of indoor air quality, such as CO2, CO, IP, bacteria, atmospheric ions and VOCs have been determined in 3 typical indoor communication environments in an office building in Beijing. The results showed that the above indicators were detected positively and the concentrations of typical VOSs as benzene and its homo-logues were at a higher level. There exists the correlation among these indicators, the mean values and the tendency in one day; especially, there are positive or negative correlation between atmospheric ions with inorganic pollutants such as CO2 and CO, organic reductive pollutants such as benzene and its homologues, biological pollutants such as bacteria and physical ones as IP. The concentration of atmospheric ions may be a fine comprehensive index to evaluate the quality of indoor air.
