It will only take a few hours. Scientists have found an effective way to clean the air from toxic substances

A new study by scientists at the Sydney University of Technology (UTS) in Australia says a vertical wall system equipped with houseplants can help purify the air of harmful compounds.

During the study, the scientists used a collection of houseplants that mimicked the Ambius system, which consists of small vertical walls kept in closed rooms for experiments. Note that the size of the lab doesn’t quite match the size of public spaces, but the idea is that installing vertical gardens in addition to ventilation systems can help clear stale air in office buildings, hospitals, schools, and other spaces.

The results of the study show that over a standard working day, plants are able to reduce the levels of some notorious concentrated compounds to levels up to 20% lower than their original concentrations. The study has yet to undergo peer review, but it confirms previous studies showing that houseplants can absorb gaseous compounds called volatile organic compounds (VOCs).

In their research, scientists used common houseplants, including:

• golden epipremnum (Epipremnum aureum);
• leg-leaved syngonium (Syngonium podophyllum);
• Crested chlorophytum (Chlorophytum comosum).

According to the study’s co-author, UTS environmental scientist Fraser Torpey, he and his colleagues have found that plants are the most effective at removing harmful pollutants from the atmosphere, not only removing most airborne pollutants within a few hours. weather.

In the study, Tropi and colleagues tested a vertical gardening system using nine custom-made plexiglass boxes with four or no plants. A small amount of gasoline evaporated inside the chambers, and the researchers measured the level of the gas.

The results show a slight reduction in gases in the laboratory chambers, but does not rule out a leak. However, the researchers are confident that vertical gardens remove about 43% of the total volatile organic compounds within 8 hours and nearly all of the three most dangerous classes of harmful chemicals:

• 98% alkanes;
• 86% benzene derivatives;
• 88% cyclopentans.

Note that these pollutants can cause “noticeable health effects” and significantly affect the maintenance of a healthy indoor environment. For example, benzene compounds are known to be highly carcinogenic and can enter schools and buildings hundreds of meters from the original source. Scientists have also known for a long time that people who live near gas stations are more likely to develop cancers such as leukemia.

Now Torpey and colleagues believe more research is needed, but it’s likely that vertical gardens actually help purify indoor air effectively. However, scientists note that we are talking about vertical gardens, and not just indoor plants on the windowsill, since the first depends on air pumps, which play an important role in the process of air purification.
