摘要

本研究旨在探讨在室内空间放置植物对室内空气污染物的减少。野外测量使用了经美国国家航空航天局(NASA)认证为空气净化植物的短叶梧桐(Aglaonema brevispathum)、水龙树(Pachira aquatica)和榕树(Ficus benjamiana)。在两个尺寸相同的独立房间中使用了植物数量和位置的三种条件。在植物放置后3小时和放置后3天监测挥发性有机化合物(VOCs)的浓度。监测了挥发性有机化合物主要成分苯、甲苯、乙苯、二甲苯(BTEX)和甲醛的浓度变化。在植物放置于空间3小时和3天后,监测甲苯和甲醛浓度的降低量。当植物存在时,苯、甲苯、乙苯、二甲苯和甲醛的浓度降低幅度更大。当植物被放置在窗户附近时,浓度的降低幅度更大。种植的植物越多,室内空气污染物的减少就越多。当植物数量增加和植物放置在阳光充足的地方时,降低空气污染物浓度的效果增强。当灯盏草占模型空间的10%时,甲苯浓度降低了45.6 μ g/m(3)。

The impact of plants on the reduction of volatile organic compounds in a small space.

This study aims at examining the reduction of indoor air contaminants by plants placed in an indoor space. Field measurements were performed using Aglaonema brevispathum, Pachira aquatica, and Ficus benjamiana, which were verified as air-purifying plants by NASA. Three conditions for the amount of plants and positions were used in two separate rooms whose dimensions are identical. The concentration of Volatile Organic Compounds (VOCs) was monitored three hours after the plants were placed and three days after the plants were placed. The variations of concentration of Benzene, Toluene, Etylbenzene, and Xylene (BTEX), as well as Formaldehyde, which are all known as the major elements of Volatile Organic Compounds were monitored. The amount of reduction in concentration of Toluene and Formaldehyde was monitored 3 hours and 3 days after the plants were placed in the space. The reduction in the concentration of Benzene, Toluene, Etylbenzene, Xylene, and Formaldehyde was significantly greater when plants were present. When plants were placed near a window, the reduction of concentration was greater. The more plants were used, the more a reduction of indoor air contaminants occurred. The effect of reducing the concentration of air contaminants increased when the amount of plants increased, and when the plants were placed in sunny area. The concentration of Toluene was reduced by 45.6 microg/m(3) when 10% of the model space was occupied by Aglaonema brevispathum.

期刊介绍: Journal of Physiological Anthropology (JPA) is an open access, peer-reviewed journal that publishes research on the physiological functions of modern mankind, with an emphasis on the physical and bio-cultural effects on human adaptability to the current environment. The objective of JPA is to evaluate physiological adaptations to modern living environments, and to publish research from different scientific fields concerned with environmental impact on human life. Topic areas include, but are not limited to: environmental physiology bio-cultural environment living environment epigenetic adaptation development and growth age and sex differences nutrition and morphology physical fitness and health Journal of Physiological Anthropology is the official journal of the Japan Society of Physiological Anthropology.
