君子兰、虎尾兰对室内环境的改善及有害物质吸收试验

为探讨植物净化室内空气，吸收污染物的效果，我们用虎尾兰、君子兰做试材，开展一系列有针对性的试验。结果表明：在一定浓度污染物范围内，虎尾兰在一周内可吸收室内甲醛总量的64．6％，二甲苯总量的61．4％，总挥发性有机物（TVOC）总量的64．8％；君子兰在一周内可吸收室内甲醛总量的70．1％，二甲苯总量的33．6％，总挥发性有机物（TVOC）总量的56．6％。

Tests of Clivia miniata and Sansevieria trifasciata on the improvement of interior enviroment and the absorption of pernicious matter.

In order to inquire into the effects of plants on the purification of indoor air and the absorption of pollutant, we have carried out a series of counterful tests, using Sansevieria trifasciata and clivia miniata as tests materials. The results show that in the scope of such degree density of pollutant, Sansevieria trifasciata could absorb 64.4% the total of formaldehyde, 61.4% of dimethylbenzene, 64.8% of TVOC and clivia miniata could absorb 70. 1% the total of formaldehyde, 33.6% of dimethylbenzene, 56.5% of TVOC within a week.
