摘要
[目的]研究新装修教室内甲醛、臭氧的浓度及在开放条件下有关植物对污染性气体的净化能力。[方法]以陕西某高校为例,在其新装修的教学八楼、教学九楼内共选取12个样点教室,采用便携式智能气体检测仪器对其甲醛与臭氧浓度进行监测。于每天07：00-08：00和21：00-22：00分别监测1 h,连续监测30 d,得到监测点的平均水平即为该点甲醛和臭氧的浓度水平。[结果]两栋教学楼内甲醛浓度均远低于国家标准值;臭氧浓度均与国家标准浓度相差不大,在标准值上下浮动。其中早晨甲醛水平高于夜晚,而臭氧则为夜晚水平高于早晨。在教学八楼的3间样点教室内摆放绿萝、常春藤及吊兰,另外3间样点教室中不摆放植物,一个月后对比测定结果,显示摆放植物的3间教室甲醛浓度明显降低。[结论]新装修教室内甲醛、臭氧的浓度不会对教师和学生的身体产生危害。在相同的开放空间中,植物对室内甲醛的净化作用比较明显。
[ Objective ] To know the concentration levels of indoor formaldehyde and ozone, and the ability of plants for eliminating air pollution. [ Method ] 12 classrooms from 2 newly interior decoration teaching buildings （No. 8 and No. 9） in Shaanxi Normal University were selected for analysis. The concentrations of formaldehyde and ozone were monitored by the portable intelligent professional gas detector. In each day ,the formaldehyde and ozone concentrations were detected during 07：00 - 08：00 and 21：00 - 22：00 for 1 hour, respectively, and this work was continued for 30 days. The average value for each site represented its concentration level. [ Result ] The concentrations of formaldehyde in both of the two buildings were far below the value of national standard, and the concentrations of ozone in both of them were closer to the value of national standard. The concentration of formaldehyde in the morning was higher than that in the night ,while the concentration of ozone in the night was higher than that in the morning. Scindapsus aureus, ivy and bracket-plant were put into the three classrooms in the teaching building （ No. 8 ）, and the other three classrooms in the same building were used as control. The result of monitor indicated that the concentration of formaldehyde decreased distinctively in one month of which classrooms put into plants. [ Conclusion] Formaldehyde and ozone concentrations in the newly interior decoration teaching buildings could not cause harm on teachers＇ and students＇ health. In the same open space, purification effect on indoor formaldehyde by nlant was obvious.
