摘　　要：[目的]了解居室装修后室内空气中苯的污染来源和控制措施。[方法]选择新装修居室40户,分为5个组（每组8户）,按聚氨脂漆用量的多少及使用人造板材填充家具分为高、低用量组及家具填充组和2个对照组,按照GB 50325—2010《民用建筑工程室内环境污染控制规范》方法测定苯的浓度。[结果]聚氨脂漆高用量组苯浓度为0.076~1.04 mg/m3;低用量组苯浓度为0.009~0.239 mg/m3;家具填充组苯浓度为0.051~0.143 mg/m3,与对照组比较,差异具有统计学意义（P〈0.05）。[结论]居室装修中苯污染与聚氨脂漆的用量及质量、家具的填充量有关,控制漆类产品的用量和质量、家具填充量和家具环保程度是预防装修中苯污染的主要措施。[Objective] To source benzene as an indoor air pollutant after residential decoration and find control measures. [Methods] Newly decorated residential houses（n=40） were selected and categorized into three test groups（based on the usage of polyurethane varnish and furniture installation） and two control groups. Benzene concentrations were determined with the method recommended by the Code for indoor environmental pollution control of civil building engineering（GB 50325-2010）. [Results] The benzene concentrations were in the range of 0.076-1.04 mg/m3 for the high polyurethane varnish group and 0.009-0.239 mg/m3 for the low polyurethane varnish group. The benzene concentrations of the furniture installation group were in the range of 0.051-0.143 mg/m3, and statistical significances compared with the control groups were found（P〈0.05）. [Conclusion] Indoor benzene pollution level is related to the amount and quality of polyurethane varnish and furniture load. Therefore, controlling the usage and quality of painting products and furniture are the key prevention measures against benzene pollution in newly decorated residential houses.
