几种观叶植物对室内污染物的净化效果研究

Effects of plants on the absorption of indoor pollutants

为了寻求减少室内空气污染物的措施和技术,我们用吊兰、虎尾兰、君子兰和橡皮树做为试材,开展一系列有针对性的试验。结果表明,这4种室内观叶植物都能吸收室内有毒有害气体,但作用效果差异明显。虎尾兰效果最佳,7 d内室内甲醛总量的减少率比对照多64.6%,二甲苯总量的减少率比对照多61.4%,总挥发性有机物(TVOC)总量的减少率比对照多64.8%;而橡皮树的作用效果最差。

In order to seek the measures and techniques to reduce indoor air pollutants,a series of couaterful tests were carried out, using four plants such as Sansevieria trifasciata, Chlorophytum capense, Clivia miniata, Ficus elastica as testing materials. The results show that all theses plants can absorb interior poisonous and harmful air. The difference of absorption effect is clear. The effect of Sansevieria trifasciata is the best, compared with antitheses ,which can absorb 64.6% the total of formal dehyde,61.4% of dimethylbenzene,64.8% of TVOC within seven days. The effect of Ficus elastica is the worst.
