【摘要】：[目的]调查居室装修后的室内空气污染状况,分析甲醛及挥发性有机污染物浓度随时间推移的变化趋势。[方法]随机选择95户装修竣工时间分别为3个月、3个月～、6个月～、9个月～、12～24个月的居室作为装修组,20户装修时间超过5年的居室作为对照组,测定室内空气中甲醛、苯、甲苯、(对、间、邻)二甲苯和乙苯浓度。[结果]装修组室内甲醛、苯、甲苯、二甲苯、乙苯的平均含量分别为0.139、0.163、0.294、0.325、0.152mg/m3,均明显高于对照组(P0.05);各污染物的超标率在37.9%～80.0%,其中超标率最高的是甲醛。装修后3个月内甲醛、苯、甲苯、二甲苯和乙苯浓度较高,分别为0.297、0.391、0.535、0.594、0.454mg/m3。3个月以后,室内污染物浓度逐渐降低,约于1年后下降到国家标准。[结论]居室装修可造成较严重的室内空气污染,随着竣工时间的延长,室内污染物浓度逐渐下降。
[Abstract]:[Objective] investigate the indoor air pollution after indoor decoration, analysis of formaldehyde and volatile organic pollutant concentration change with time. Method: randomly selected 95 households completed renovation time were 3 months, 3 months, 6 months, 9 months to 12~24 months, in the living room as 20 household decoration decoration group, more than 5 years of living as the control group, the determination of formaldehyde in indoor air, benzene, toluene, (yes, O) xylene and ethylbenzene concentration. The decoration group of formaldehyde, benzene, toluene, xylene, ethylbenzene, the average content of 0.139,0.163,0.294,0.325,0.152mg/m3 respectively, were significantly higher than the control group (P0.05); the rate of exceed the standard pollutants in 37.9% ~ 80%, which is the highest rate of formaldehyde exceed the standard decoration. Within 3 months after the formaldehyde, benzene, toluene, xylene and ethylbenzene concentration were 0.297,0.391,0.535,0.594,0.454mg/m3.3 months later, indoor The pollutant concentration decreased gradually, about 1 years after falling to the national standard. Conclusion] room decoration can be caused by indoor air pollution is more serious, with the extension of time for completion, the indoor pollutant concentration decreased gradually.
