“…The composition of wax was reported to be the main factor for benzene uptake . In the 21 plant leaf materials screened for benzene adsorption, some leaf materials could adsorb high amounts of benzene and had high capacity . In the continuous adsorption system, selected plant leaves were immobilized on glass beads by cassava adhesives for benzene adsorption with the retention time of 3–5 min (55 ppm initial benzene concentration).…”

“…The new absorbents from the plant leaf materials were interesting because of price, waste recycling, and easy secondary waste disposal. Twenty one plant leaf materials were screened for benzene adsorption in a fumigatory chamber; some plant leaf species such as Dieffenbachia picta , Acrostichum aureum , Ficus religiosa , Lagerstroemia macrocarpa , Alstonia scholaris , and Dracaena sanderiana adsorbed high amounts of benzene and had high benzene adsorption capacity . Many factors such as surface area, quantity of wax, and the composition of wax can cause different benzene uptake efficiencies of each plant material.…”

Dieffenbachia picta, Acrostichum aureum, Ficus religiosa, Lagerstroemia macrocarpa, Alstonia scholaris, and Dracaena sanderiana leaf materials have high benzene removal efficiency. So, these six plant leaf materials were investigated for continuous adsorption systems. In adsorption systems, A. aureum and A. scholaris leaf materials were found to have the highest benzene removal capacity. Physical sorption was confirmed by hexane desorption and Fourier transform infrared spectrometry (FT-IR). Pseudomonas putida immobilized on A. aureum and A. scholaris leaf cassava-beads were used as biofilters. A total of 1.2-1.5 min with an enrichment medium was shown to be the suitable retention time and suitable nutrients for the biofilter system.Abbreviations: BET, Brunauer, Emmett, and Teller; FT-IR, Fourier transform infrared spectrometry. 915

“…Many studies have found plants can adsorb and absorb air pollutants (Dela Cruz et al 2014;Kim et al 2008;Soreanu et al 2013;Treesubsuntorn et al 2013). Leaf adsorption and absorption by metabolic processes were the two main processes plants used to decrease air pollutants (Fujii et al 2005;Sriprapat et al 2014).…”

Effects of trait variation, environment, and phylogeny on the air pollutant removal capacity of indoor plants

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.

“…Several studies have isolated aboveground plant parts from the root zone and substrate with the use of physical barriers, and have concluded that leaves are capable of VOC removal (Lin et al, 2007;Tani et al, 2007;Tani and Hewitt, 2009;Treesubsuntorn and Thiravetyan, 2012;Sriprapat and Thiravetyan. 2013;Treesubsuntorn et al, 2013;Sriprapat et al, 2014a;Sriprapat et al, 2014b). While stomatal uptake offers one possible means of VOC removal by the aerial part of the plant, some VOCs are also able to become adsorbed to or diffuse across the cuticle (Baur and Schönherr, 1995;Treesubsuntorn et al, 2013), with some authors suggesting that removal by the cuticle is depenendent on wax quanity and chemical structure (Treesubsuntorn et al, 2013).…”

Towards practical indoor air phytoremediation: A review

2018

View full text Add to dashboard Cite

Indoor air quality has become a growing concern due to the increasing proportion of time people spend indoors, combined with reduced building ventilation rates resulting from an increasing awareness of building energy use. It has been well established that potted-plants can help to phytoremediate a diverse range of indoor air pollutants. In particular, a substantial body of literature has demonstrated the ability of the potted-plant system to remove volatile organic compounds (VOCs) from indoor air. These findings have largely originated from laboratory scale chamber experiments, with several studies drawing different conclusions regarding the primary VOC removal mechanism, and removal efficiencies. Advancements in indoor air phytoremediation technology, notably active botanical biofilters, can more effectively reduce the concentrations of multiple indoor air pollutants through the action of active airflow through a plant growing medium, along with vertically aligned plants which achieve a high leaf area density per unit of floor space. Despite variable system designs, systems available have clear potential to assist or replace existing mechanical ventilation systems for indoor air pollutant removal. Further research is needed to develop, test and confirm their effectiveness and safety before they can be functionally integrated in the broader built environment. The current article reviews the current state of active air phytoremediation technology, discusses the available botanical biofiltration systems, and identifies areas in need of development.
