摘　　要：目的探讨不同装修程度居室空气中苯的污染现状,分析其变化趋势及防控对策。方法在贵阳市住宅小区选择新装修居室,按使用各类人造板材及聚氨酯清漆的用量、外购家具装填情况等装修水平的不同分为3个实验组（每组8户）,低装修水平1组,高装修水平1组,家具装填1组;设未使用人造板材、聚氨酯清漆和家具装填的1组（对照组）,对上述组别中苯共作5次监测（15 d监测1次）,测定方法按（GB 50325-2010）热解析-气相色谱法。结果低水平组第1次监测苯浓度范围（0.009-0.240 mg/m3）,显著低于高水平组（0.078-1.040 mg/m3）和家具装填组（0.077-0.140 mg/m3）;3个实验组苯浓度均高于对照组（P〈0.05）,至第5次监测,家具装填组的苯浓度水平（0.009-0.089 mg/m3）〉高水平组（0.009-0.075 mg/m3）。同时,随时间的延长,各实验组苯浓度呈下降趋势。结论高装修水平组和家具装填组室内苯浓度明显高于低装修水平组,主要与人造板材、聚氨酯清漆的用量和质量、家具的装填和质量相关。Objective To investigate the pollution condition for benzene in indoor air after decoration.And to analyze the variation regularity and control measures.Methods Selected the newly decorated houses 32 households in Guiyang City.According to the amount of polyurethane varnish and furniture filled condition were divided into three test groups：low level decoration group,high level decoration group,furniture filled decoration group.Set unused artificial plate,polyester varnish and furniture filled group as control group.Did five monitoring for benzene in these four groups.Used thermal desorption gas chromatography（GB 50325-2010）in determination of benzene.Results In first monitoring,benzene concentration range（0.009-0.24 mg/m3） in the low level group was significantly lower than the high level group（0.078-1.04mg/m3） and furniture filling group（0.077-0.14mg/m3）.The benzene concentration of three experimental groups were higher than those in the control group.To fifth time monitoring,benzene concentration level in furniture filled group（0.009-0.089mg/m3） was higher than in the high level group（0.009-0.075mg/m3）.At the same time,with the time prolonged,the benzene concentration decreased.Conclusion The indoor benzene concentrations in high level decoration group and furniture filling group are higher than that of the low level decoration group.And the pollution condition of benzene is mainly related with the amount and quality of polyurethane varnish,artificial plate and furniture loading.
