【摘要】：[目的 ]观察开窗时间对室内空气中苯和甲苯浓度的影响。 [方法 ]苯和甲苯浓度的测定方法按照GB1173 7 89。选 16间新装修房间 ,竣工后第 2天开始观察 ,随机分为 4组 ,每 4间房间为一组 ,各组每天的开窗时间分别的 0、2、4、6h。隔日测定苯和甲苯的浓度 ,共 9d。 [结果 ]①苯 :2、4h组与 0h组 (对照组 )比较差异无显著性 :6h组与对照组比较差异有显著性 (P 0 .0 5 )。与本组第 1天的浓度比较 ,0、2、4、6h组分别在第 7、5、7、3天以后差异有显著性 (P 0 .0 5 )。②甲苯 :2、4、6h组与对照组比较分别在第 9、3、7天以后差异有显著性 (P 0 .0 1、P 0 .0 5、P 0 .0 5 ) ;0、2、4、6h组与本组第 1天的浓度比较分别在第 5、3、3、3天以后差异有显著性 (P 0 .0 5 )。 [结论 ]开窗时间越长 ,苯和甲苯浓度降低越明显
[Abstract]:[objective] to observe the effect of window opening time on the concentration of benzene and toluene in indoor air. [methods] the concentration of benzene and toluene was determined according to GB1173 7 89. Sixteen newly decorated rooms were selected and observed on the second day after completion. They were randomly divided into 4 groups, each four rooms as a group. The concentrations of benzene and toluene were determined every other day for 9 days. [results] 1There was no significant difference between the control group and the 2h group (control group). There was no significant difference between the control group and the control group (P0. 05). Compared with the first day, there was a significant difference in the concentration between the control group and the control group after the 7th day (P 0. 0. 0 5) and the control group after 7 days (P 0. 01 P 0. 0. 0. 0 0. 0. 0. 0 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. There were significant differences in the concentrations between the two groups and the first day after 3 days, respectively. There was a significant difference between the two groups after 3 days (P 0. 05). [conclusion] the longer the window opening, the lower the concentration of benzene and toluene.
