摘　　要：目的了解装修材料销售场所室内空气中苯系物的污染状况,为职业健康防护提供依据。方法检测30家装修材料销售店,分别对其室内空气中苯、甲苯、二甲苯进行检测。结果各类装修材料销售店室内空气中苯、甲苯、二甲苯合格率较低,以人造板材店的合格率最低。加强销售场所的通风,能降低苯、甲苯、二甲苯的浓度;店面积大小对其合格率有影响。结论装修材料销售场所空气中苯、甲苯、二甲苯污染严重,其污染的程度与销售装修材料的类型、店面大小、通风状况等有关。职业病防治部门应加强建筑装修材料销售场所现场空气的监测和作业人群的健康监护。Objective To understand the indoor air contamination condition of benzene series compounds in constructional ornamental materials sale stores and to offer data for occupational health protection. Methods Thirty sale stores were randomly selected to measure the concentration of benzene, methylbenzene and xylene when their doors and windows were opened and closed respectively. Results In constructional decorating material sale stores, benzene, methylbenzene and xylene were higher than outdoors. The peak value of benzene was 13.8 times exceeded than that of the hygienic standard. The rate of up to the hygienic standard showed significant differences among the different sale stores. The rate of up to the hygienic standard of benzene series was different among the different area of sale store. The larger was the area of sale store, the higher was the rate of up to the hygienic standard. The rate of up to the hygienic standard of benzene series in artificial plank material store was the lowest. In ventilation condition, the concentrations of benzene, methylbenzene and xylene were decreased （P〈 0.05）. Conclusions The indoor air in decorating material stores is badly polluted from the benzene series compounds, and the degree of pollution is correlated to the material category, the area of sale store and ventilation. We should strengthen monitoring for indoor air in the constructional ornamental materials sale stores and the health protection for the occupational crowd.
