“…Similarly, Sriprapat and Thiravetyan (2016) identified benzene degrading bacteria in the phyllosphere and found that potted-plants with sterilized leaf surfaces exhibited decreased benzene removal rates, while plants inoculated with the identified endophytic benzene-degrading bacteria showed an increased benzene removal efficiency in comparison to ordinary potted-plants. De Kempeneer et al, (2004) showed that toluene removal rates could be increased by inoculating the leaf surface with a culture of toluene-degrading bacteria.…”

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.

“…These species were Spathiphyllum wallisii (peace lily) and Syngonium podophyllum (arrowhead vine). These species are both common indoor houseplants and green wall species, and both have been tested for their capacity to phytoremediate a range of VOCs [33,[45][46][47][48][49][50]. All tested plants were grown in their biofilters in a glasshouse (Sydney, Australia) for~8 weeks prior to testing.…”

An Assessment of the Suitability of Active Green Walls for NO2 Reduction in Green Buildings Using a Closed-Loop Flow Reactor

et al. 2019

Nitrogen dioxide (NO 2 ) is a common urban air pollutant that is associated with several adverse human health effects from both short and long term exposure. Additionally, NO 2 is highly reactive and can influence the mixing ratios of nitrogen oxide (NO) and ozone (O 3 ). Active green walls can filter numerous air pollutants whilst using little energy, and are thus a candidate for inclusion in green buildings, however, the remediation of NO 2 by active green walls remains untested. This work assessed the capacity of replicate active green walls to filter NO 2 at both ambient and elevated concentrations within a closed-loop flow reactor, while the concentrations of NO and O 3 were simultaneously monitored. Comparisons of each pollutant's decay rate were made for green walls containing two plant species (Spathiphyllum wallisii and Syngonium podophyllum) and two lighting conditions (indoor and ultraviolet). Biofilter treatments for both plant species exhibited exponential decay for the biofiltration of all three pollutants at ambient concentrations. Furthermore, both treatments removed elevated concentrations of NO and NO 2 , (average NO 2 clean air delivery rate of 661.32 and 550.8 m 3 ·h −1 ·m −3 of biofilter substrate for the respective plant species), although plant species and lighting conditions influenced the degree of NO x removal. Elevated concentrations of NO x compromised the removal efficiency of O 3 . Whilst the current work provided evidence that effective filtration of NO x is possible with green wall technology, long-term experiments under in situ conditions are needed to establish practical removal rates and plant health effects from prolonged exposure to air pollution.

“…Selain itu tanaman juga mampu menurunkan tingkat polusi lingkungan dan menghijaukan lingkungan. Kemampuan tanaman hias dalam mengurangi polutan berbahaya menjadikan tanaman yang awalnya hanya dianggap sebagai tanaman hias menjadi solusi bagi masyarakat untuk mengurangi tingkat pencemaran udara (Dela Cruz et al, 2014;Sriprapat and Thiravetyan, 2016). Adapun tujuan dari penelitian ini yaitu untuk (1) memilih 4 jenis tanaman hias berpotensi menjerap debu yang dihasilkan oleh kendaraan bermotor di Bumi Serpong Damai, dan (2) mengukur massa debu yang terjerap dari 4 jenis tanaman hias yang ditanam di jalur hijau Bumi Serpong Damai.…”

<p style="margin-bottom: 0.35cm; line-height: 115%;" align="justify">This research measured several vegetations that were planted in Bumi Serpong Damai, South Tangerang to absorb dust pollutions produced by vehicles. The locations for monitoring were divided based on traffic levels: high, medium and low. We measured the pollution based on two approaches i.e. measuring every four hours and a daily measurement. Based on our monitoring, each species will have different feedbacks to dust pollution at various traffic conditions. We found that species of <em>Heliconia</em> was able to absorb the dust at the top for high traffic condition, whereas Kaca Piring is effective for medium traffic. Our findings revealed that monitoring dust should be frequent at least four hours/day, and selection of species for reducing dust pollution should consider the leave structure. </p>
