摘要
[目的 ]了解家具城室内空气污染情况。 [方法 ]于冬夏二季对北京市 9家家具城室内空气质量进行了检测 ,分析影响因素 ,同时对家具城从业人员进行了主观感觉 ,呼吸道症状发生率及甲醛个体接触剂量调查。 [结果 ]冬季室内空气中甲醛平均浓度为 0 .16 mg/m3,超出公共场所卫生标准 (0 .12 mg/m3) 0 .3倍 ,样品超标率为 6 1%。夏季平均浓度为 0 .5 2 mg/m3,高于公共场所卫生标准 3.3倍 ,样品超标率为 98%。冬夏季从业人员甲醛平均接触浓度分别为 0 .19m g/m3和 0 .5 6 mg/m3。夏季室内空气中氨的最大值为 1.0 2 mg/m3,高于公共场所卫生标准 (0 .5 0 mg/m3) 1倍 ,平均浓度为 0 .32 mg/m3,低于公共场所卫生标准 ,样品超标率为 10 %。从业人员主观感觉、呼吸道症状发生率与不售家具的百货商场相比 ,差异有显著性 (P<0 .0 5 )。 [结论 ]板材卫生质量、生产时间、家具摆放密度、室内温度和湿度是是影响家具城室内空气质量的主要因素 ,家具城环境对从业人员健康影响值值得深入研究。
Objective]To anderstand the indoor air pollution in furniture markets [Methods]The sanitary qualities of indoor air of funiture markets were detected and their relative factors were analysed in Beijing in winter and summer The subjective sensations,the prevalance rates of symptoms in respiratory system and personal expoure dose of formaldehyde of the employees in the furniture markets were also investigated [Results]The average concentration of farmaldehyde in indoor air was 0 16 mg/m 3,which exceeded 0 3 times as high as that of the sanitary standard for public places(0 12 mg/m 3),and the over standard rate for the air samples was 61% in winter The corresponding data in summer was 0 52 mg/m 3,3 3 times and 98% respectively The personal exposure dose of formaldehyde among employees was 0 19 mg/m 3 in winter and 0 56 mg/m 3 in summer respectively The highest concentration of ammonia in indoor air was 1 02 mg/m 3,which exceeded one time as high as that of the sanitary standard for public places (0 50 mg/m 3) The average concentration of ammonia was lower than standard(0 32 mg/m 3) The over standard rate of ammonia in air samples was 10% Significant differences were found in the positive rate of uncomfortable feelings,and the occurrence rate of symptoms respiratory system of the employees in furniture markets compared with the department stores without saling of furnitures( P<0 05 ) [Conclusion]The main factors effecting the sanitary quality of indoor air of furniture market were definited as follows,the sanitary quality of plywood,period after production,displaying density of furnitures and indoor temperature and moisture It was worth to research the effects of the enviroment of furniture market on employees' health
