摘　　要：目的了解不同装修程度室内挥发性有机物(VOCS)的污染现状,分析其来源并探讨相应防控对策。方法按装修程度将监测对象分低、中、高和家具装填4个组别(每组12户),第1次监测在装修完工后10 d,以后每隔1个月监测1次,至第7次,按《民用建筑工程室内环境污染控制规范》(GB 50325–2010)中热解吸—气相色谱法测定室内VOCs的含量。结果中程度装修组(2.21±0.26)mg/m3、高程度装修组(3.68±0.49)mg/m3和家具装填组(10.67±7.71)mg/m3室内VOCs的质量浓度显著高于低程度装修组(1.04±0.36)mg/m3,家具装填组室内VOCS平均质量浓度高于其他各组,秩合检验差异有统计学意义(P<0.05);随时间的延长,各实验组VOCS质量浓度呈下降趋势,降低到安全水平的时间依次为131、161、161和191 d。结论不同装修程度室内VOCS暴露水平与装饰材料的用量相关,控制材料的质量、家具的环保程度、适宜的入住时间是防止VOCS的室内暴露而致人体不良健康效应的主要措施。Objectives To understand the status of volatile organic compounds（ VOSs） pollution in decorated rooms,and to analyze its sources and preventive measures. Methods The monitoring data were classified into 4groups according to the degree of decoration（ low,middle and high） and furniture loading. There were 12 rooms in each group. The monitoring was started from 10 days after decoration,and then monitoring once every month for 7times. The content of VOSs was determined by gas chromatography（ GB 50325- 2010）. Results The level of VOSs was（ 2. 21 ± 0. 26） mg /m3 in the middle decoration group,（ 3. 68 ± 0. 49） mg /m3 in the high decoration group and（ 10. 67 ± 7. 71） mg /m3 in the furniture loading group,which were significantly higher than（ 1. 04 ±0. 36） mg /m3 in the low decoration group（ P 〈 0. 05）. The concentration of VOCs was decreasing with the length of time passing; and it took 131 days,161 days,161 days and 191 days for low,middle and high decoration groups and furniture loading group to come to a security level of VOCs. Conclusions The level of VOCs exposure in rooms was related to the degrees of decoration. Effectively controlling the quality and the amount of decoration materials,and choosing green furniture and right time to move in the decorated rooms might be the main measures to prevent adverse health effects caused by VOCs indoor exposure.
