Abstract

Indoor air quality of the new building has become a major concentration in China. Volatile organic compounds (VOCs) in new buildings were investigated and factors significant to their presence were discussed. Concentrations of volatile organic compounds, temperature and humidity were measured in four new apartment buildings over 6 months following installation. Formaldehyde concentrations in the new buildings were relatively low in the new buildings, which can satisfy the Indoor air quality standard of 0.10mg/m3. But the benzene and total volatile organic compound (TVOC) concentrations were extremely higher indoor, they were approximately three to four times higher than IAQ standard. Simultaneous outdoor samples were also collected to determine indoor to outdoor I/O. ratios for every compound at each location, which showing a dominant effect of indoor sources. The study revealed that the indoor concentrations of selected VOCs on occasions could be significantly high due to various sources. The data presented here can be useful in developing air quality standards for indoor air.

中国哈尔滨市新建公寓楼挥发性有机化合物浓度

新建筑的室内空气质量已成为中国关注的焦点。对新建建筑的挥发性有机化合物(VOCs)进行了调查，并对影响其存在的因素进行了讨论。在四栋新公寓楼安装后的6个月内，测量了挥发性有机化合物的浓度、温度和湿度。新建建筑甲醛浓度较低，满足室内空气质量标准0.10mg/m3。但室内苯和总挥发性有机化合物(TVOC)浓度极高，约为室内空气质量标准的3至4倍。同时还收集了室外样品，以确定室内到室外的I/O。每种化合物在每个位置的比值，显示出室内源的主要影响。研究表明，由于各种来源的影响，某些VOCs的室内浓度有时会很高。这里提供的数据可以用于制定室内空气质量标准。
