Houseplants may extract which pollutant from the air

Over-watering indoor plants can lead to cosmetic and even moisture-related structural problems, as well as mold and other serious indoor air quality issues. In summary, plants can generally be used to enhance the aesthetic environment and the air quality inside buildings, but care must be taken to account for potential allergies, the use of fertilizers and pesticides indoors, adequate ventilation and air flow, and the level of moisture maintained for the plants -- all factors that can affect the building and its occupants.

In the course of three days, the level of chloroform dropped by 82 percent, and after eight days, the level of benzene dropped by 75 percent.

This powerful air-purifying plant is currently available in Canada, and researchers are seeking approval from the Department of Agriculture for its sale in the United States.

Intro Air quality Houseplant benefits 9 houseplants Potting tips In the future A quick scroll through Instagram will tell you just how trendy indoor foliage has become.

Impeller fans ensured mixing of the gases within the chambers. This depletion rate was used as an indicator that the aerial portion of the plant was assisting in ozone mitigation. Air circulation within the chambers continued during all trials.

Five spider plants, five golden pothos plants, and two snake plants because of their larger size per replication were used in this evaluation. During the evaluations, the top part of each pot was enclosed with plastic sheeting in such a manner that only the aerial portion of the plants was exposed to ozone.

One chamber that did not contain any plants served as control. At the completion of the evaluations, leaf surface area and stomatal conductance g S of the plants were measured. The experiment was conducted as a completely randomized design with plant species as the main effect replicated six times trials over the course of 3 d 27 June , 28 June , and 3 July under similar environmental conditions Table 1. Three of the trials were conducted during the late morning am and three trials were conducted during the early afternoon pm ; day and time of day am or pm were noted for each trial.

The plant species evaluated were alternated among specific chambers during the replications over time to exclude any possible chamber effect. The same individual plants within species were used for all trials. Environmental conditions of temperature and relative humidity in the continuously stirred tank reactor chambers during the six trials conducted in to test the effectiveness of houseplants in reducing ozone.

Ozone depletion depends on the uptake of ozone by the plant species, therefore it was not appropriate to use a simple decay formula. The absolute value of slope of the depletion curves i. General Linear Model GLM was used to determine the significant factors affecting the depletion curves. Day, time of day am or pm , chamber, and treatments e.

Analysis of variance of the six trials determined that there was no day or time of day am vs. The negative slopes of the ozone curves from the experimental treatments indicated that ozone was mitigated from the chambers among the four treatments Fig.

Analysis of variance comparing day, time of day late morning versus early afternoon , and plant species snake plant, spider plant, and golden pothos on absolute slope of the ozone depletion curves. Sampled ozone concentrations over time among the plant chamber treatments used to evaluate the effectiveness of houseplants in reducing ozone concentrations.

Citation: HortTechnology hortte 19, 2; The absolute slope of the control treatment was the smallest and was significantly different from the golden pothos and snake plant treatments, but similar to the spider plant.

Influence of selected houseplants on ozone concentrations within chambers over time. The control chamber did not contain any plants. There were statistical differences in g S Table 4 among the plant species evaluated. The spider plant had the greatest conductance, while the golden pothos had the least, and snake plant was intermediate. G S rates and leaf surface area of houseplants evaluated for their effectiveness in reducing ozone concentrations within chambers. Plant species evaluated in this study snake plant, spider plant, and golden pothos were effective in mitigating ozone compared with a control that did not contain any plants from the CSTR chambers that were used to simulate a controlled interior environment.

These results are consistent to those reported by Wolverton , using similar plant species for mitigation of VOCs. Although other studies have suggested differential VOC depletion rates for plant species Wolverton, , in the current study, we were unable to identify any interspecies differences in depletion rates for ozone.

A plant's ability to reduce concentrations of ozone in its surrounding environment appears to be dependent upon uptake of ozone through the stomata and subsequent detoxification reactions within the intracellular spaces.

Therefore, the instantaneous rate at which plant surfaces absorb ozone would depend on the g S and the total leaf surface area of the plant species. Because g S per plant and total leaf area of the plants within the chambers varied among the treatments, it was not possible to determine if g S or total leaf area was the more important plant variable in mitigating ozone.

Additional research with plants of varying g S and leaf area as well as alternative nonplant materials that increased the surface area are needed to further understand these variables before more precise plant recommendations can be made. Our study did not consider soil or microorganisms as factors in determining ozone mitigation; prospectively, we plan on exposing soil and microorganisms to ozone to determine their effect of indoor ozone depletion. In conclusion, common houseplants reduce ozone concentrations in a simulated indoor setting.

As a method to reduce airborne contaminants, plant implementation may be cost effective and readily applied throughout the world. In particular, the plant species evaluated in this study were common, inexpensive, and easy to grow and maintain.

What works in a chamber study does not necessarily translate into real life settings. One difference results from trying to scale-up from a test chamber to real life. The sample sizes used in testing, such as in the NASA study, are often very small so their findings don't translate well into real-world experiences.

As a reviewer from the U. Environmental Protection Agency explained in a memo 3 on the NASA study, "to achieve the same pollutant removal rate reached in the NASA chamber study" would require having " plants in a typical house. Different plant species, types of soil, lighting, temperature and size can all vary the impact of plants on air pollution. For example, the sunlight or temperature in a room can make some plants absorb more or less pollution.

What is more, plants may even contribute to unhealthy air conditions. Some plants may release VOCs into the air. While plants can be beneficial, the evidence does not show that they are an effective tool to reduce air pollution. A review of the research in scores of studies 5 found mixed evidence in real-world studies for improved air quality indoors. The use of plants to clean the air in complex places like homes and offices needs much more study.
