“…We obtained the phylogeny of the 58 plant species by using Phylomatic (Webb Many studies use the absorption or adsorption of pollutants per leaf area as the agent of removal capacity of the study plant (Fujii et al 2005). Actually, the capacity of the plant as a whole to remove pollutants is also an important indicator of the effect of air purification, especially in practice.…”

“…Although outdoor air pollution dominates the discussions of scientists and leaders (Bascom et al 1996;Kunzli et al 2000), there is a growing body of research focusing on indoor air quality (Bruce et al 2000;Spengler & Sexton 1983), which likely has more of an impact on people's daily lives (Jones 1999;Kostiainen 1995;Mumford et al 1987). In recent years, plants have gained popularity as a means to purify polluted air (Fujii et al 2005;Soreanu et al 2013).…”

“…The stress of an artificial environment and the cultivation process may also lead indoor plants to adaptation and modification, increasing their capacity to purify air. Some evidence indicates that plants are indeed responsible for the majority of air purification (Dela Cruz et al 2014;Fujii et al 2005). Formaldehyde can be absorbed and metabolized by a plant's abaxial surface and its young leaves (Kim et al 2008).…”

Although it is well known that plants have the capacity to remove indoor air pollutants, there has been little research to investigate how this ability is regulated by the environment and evolutionary processes. In this study, we tested the capacity of 58 common indoor plants to remove three specific air pollutants. We also measured the traits, phylogenetic signals, and cultivated environments of these plants to analyze their relationship with the air pollutant removal capacity using Spearman’s correlation, Blomberg’s K test, and phylogenetic generalized least-squares. While we found trait variation had a significant correlation with removal capacity, we did not, however, detect a phylogenetic signal with removal capacity. Trait variation and environmental factors both contributed to the removal capacity in phylogenetic generalized least-squares, but again, without phylogeny. Our results show that plant trait variation, especially total leaf area, could play an important role in plant’s capacity to remove pollutants from indoor air. Moreover, environmental changes, not the phylogeny, could result in trait modification, improving the tolerance and purification capacities of these plants. The findings outlined here will help to explain how plants living with air pollution can adapt as well as the application of plants for the purpose of indoor air purification.

This study aims to suggest an improved experimental method to reveal the ability of indoor plants to reduce CO2 concentrations, as well as to display the individual CO2 reduction characteristics of various indoor plants in accordance with this improved method. In previous studies, experiments were conducted under the condition in which the CO2 concentration in the experimental chamber is set only once to a high initial level of 1,000 ppm. However, in real conditions, CO2 concentration gradually increases in a room after the occupants enter. Hence, the existing experimental method can be improved in view of "light saturation and CO2 compensation". Accordingly, in this study, the CO2 reduction characteristics of indoor plants under 2 conditions used in the existing method of measurement (Case 1) and the condition in the new method, which considers that CO2 concentration gradually increases through the respiration of experimental animals (Case 2)-were measured and compared against each other. For all plant samples, the level of CO2 reduction was higher in Case 2 than in Case 1, and the rate of CO2 reduction increases with time. The inflection point of CO2 concentration appeared at leaf areas of 9,000 cm 2 in peace lily and areca palm, and 6,000 cm 2 in weeping fig.Additional key words: CO2 reduction quantity, compensation point, indoor air quality, respiration of experimental animals Hort.

“…Burchett et al (2011) reported that several test plants actively removed VOC from air while the CO2 reduction was accomplished by green part of the plants at adequate light levels. Photosynthesis was actively performed by Juniperus conferta (a hanging indoor plant) in spring and summer in Japan absorbing large amounts of CO2 than in winter (Fujii et al, 2005). These results revealed that, though plants can fix CO2, their contribution to indoor CO2 reduction has to be studied thoroughly as CO2 emission and absorption depend on several plant-based factors.…”

Use of foliage plants for indoor decoration is pursuing tradition in several cultures. With contemporary living patterns, frequent replacement of indoor plants has become impractical. Therefore, this experiment was conducted to identify indoor plants with low carbon dioxide (CO2) emission or CO2 absorption ability in nights to be kept continuously indoors. Five common indoor plants (Cryptanthus sp., Dieffenbachia seguine, Dracaena sanderiana, Sansevieria trifasciata and Zamioculcas zamiifolia) were placed separately in 1000 L airtight chambers for 12 h in the dark. The CO2 level in each chamber was measured before and after the experiment and the difference was calculated. The stomatal count of both adaxial and abaxial surfaces was taken in each plant type to determine the relationship between CO2 emission/absorption efficiency and stomatal density of tested ornamental species. From the test plant species, D. seguine, D. sanderiana and Z. zamiifolia, showed positive CO2 equilibrium in the chambers and the CO2 increments were 0.16 ppm cm-2 , 0.39 ppm cm-2 and 0.18 ppm cm-2 of leaf area, respectively. Both Cryptanthus sp. and S. trifasciata showed negative CO2 equilibrium at around-0.20 ppm cm-2 of leaf area. Sansevieria trifasciata and D. sanderiana possessed stomata in both adaxial and abaxial surfaces, while stomatal number in adaxial surface of other three test plant species was negligible. The average number of stomata Cryptanthus sp. was 5.56x10⁴ cm⁻ 2 , D. seguine 5.03x10⁴ cm⁻ 2 , D. sanderiana 9.05x10⁴ cm⁻ 2 , S. trifasciata 5.25x10⁴ cm⁻ 2 and Z. zamiifolia 3.51x10⁴ cm⁻ 2. Stomata in Cryptanthus sp. and S. trifasciata close during day time and open at night. Present study concludes that potted Cryptanthus sp. and S. trifasciata (plants with CAM photosynthesis pathway) used for indoor decoration absorb CO2 during the night, and hence, are safe to keep indoors during day and night.
