植物对各种空气中的化学物质具有净化能力。能力很大程度上取决于植物的生长条件。在这项研究中，检查了植物在以下三种条件下生长的能力：（a）将主观植物放入一碗自来水中，（b）将其放入一盆生长水中超过一年，以及（c）放入盆土中。实验中改变了室温和光照强度。结果，很明显，对甲醛的能力根据室温而有一定程度的变化。 (a) 的情况下，性能在 12–25°C 范围内线性下降，(b) 的情况下变化不大，(c) 的情况下，在 21°C 时表现出最大值。该温度属于植物的最佳生长范围。能力顺序如下：(a)<(b)<(c)。在每种生长条件下，随着光强度的增加，能力也随之增加。还检查了对丙酮、甲苯和二甲苯的能力。很明显，随着化学品的分子量变大，能力也变低。
Plants have a purification capability to various kinds of airborne chemicals. The capability largely depends on the growing conditions of the plant. In this study, the capabilities of the plants growing in the following three conditions were examined: (a) put the subjective plant in a bowl of tap water, (b) put the one in a pot of growing water for over 1 year and (c) in the pot-soil. The room temperature and light intensity were changed in the experiments. As a result, it became obvious that the capability to formaldehyde varied in some degree according to room temperature. The capability decreased linearly in 12–25°C in the case of (a), it did not change largely in the case of (b) and it indicated maximum value at 21°C in the case of (c). The temperature belonged to optimal growth range of the plant. The capability-order is as follows: (a)<(b)<(c). The capability increased as the light intensity increased in each growth-condition. The capabilities to acetone, toluene and xylene were also examined. It became obvious that the capability became lower as the molecular weight of the chemical became larger.
