Discover 3 species of plants that help absorb toxic gas in the house

There are many ways to eliminate poisonous gases in your home, but planting trees to eliminate poisonous gases is the easiest and most economical way. The following 3 species of poisonous plants in the house will help you eliminate the impurities, improve your family's health better. For the first time, scientists at the University of Forestry have successfully researched a number of tree species that both have the effect of making beautiful scenes and being able to handle toxic gases.

What is poison gas in the house?

According to Dr. Phung Van Khoa, Vice Chairman of the Graduate Faculty, Forestry University (Xuan Mai, Chuong My, Hanoi), toluene is a volatile organic solvent and is widely used in the industry. career. In the home, toluene gas can come from a variety of sources such as paint, cigarette smoke, detergents, or can be diffused from the outdoors into the house.

Recognizing the fact that, in the open air of the people, this content has not reached a dangerous level. However, in new buildings or near production plants, near the roads, the gas content is relatively high.

According to studies, this is one of the dangerous indoor air pollutants. Because it can affect the central nervous system, make people in the home feel sleepy, headache, tired, dizzy . When in high concentrations, toluene gas can affect the brain sets, causing unconsciousness and even death.

"Choosing the right solution to reduce toxic gases such as toluene in the indoor environment is very necessary and urgent. One of the most environmentally friendly solutions has been known there. Phytoremediation is used for plants and also to make beautiful scenes , ' said Dr. Phung Van Khoa.

Magnolia can absorb toluene gas in the house.

Three species of plants should be grown indoors

Dr. Phung Van Khoa, MSc Bui Van Nang and MSc Nguyen Thi Bich Hao are researchers who use greenery to absorb toxic gas. Accordingly, the experts believe that the three species of toluene uptake of the highest of the 20 plants surveyed are Common carpets, Five family and Common ferns. This is based on the research results: After 72 hours of exposure, the device absorbs absorbent 2.7µg / cm ² (leaf area unit), absorbs 1,20µg / cm ² , the flower tree Absorption head 1,00µg / cm ² .

Also according to the authors, these three species have been selected for research because of their high aesthetics, which can be grown indoors as a ornamental plant. In addition, when exposed to toluene gas at a concentration of 8.0 - 12.0mg / m ³ , these plants still grow normally and there are no unusual signs of morphology.

Experts recommend that when planting trees, there should be a suitable density to have a high effect. For example, a house of about 10m ² should be planted with 2-3 trees, in which there should be a tree about 1m high and a canopy diameter of 0.5m, and a smaller tree placed near the working place. Because the research has proven, when leaving trees near people will help relax and increase productivity. When there is a small green tree on the desk, it not only absorbs polluted gas but also promotes creativity and ability to concentrate more.

Set of magnolia

This is a tree with leaves growing into a bow (rosette), shiny and dark, the leaves have broader, lighter stripes and yellowing at the center. It is a slow growing shrub with long leaves. Magnolia device can absorb toluene and CO.

According to the research results of the University of Forestry, the ability to absorb exposed toluene gas after 24 hours (per unit of leaf area) is 1.3 µg / cm2, 2.7 µg / cm2 after 72 hours of exposure.

Envelopes

The family tree is also known as the five-legged bird family, young ginseng. There are two common types: Five blue envelopes and five yellow envelopes. The plant is healthy, can be grown by plugging branches, cold-tolerant quite well, the average water demand.

Five family is a precious tree, often grown in interior decoration, hall, living room, .

In addition to making scenes, the five envelopes also help to repel mosquitoes and insects in the living space around the house.

According to the research results of the University of Forestry, the ability to absorb toluene gas after 24 hours of exposure of the envelope is 0.7 µg / cm2 and 1.2 µg / cm2 after 72 hours of exposure.

But even if you like to plant and decorate trees, when placing trees, you need to pay attention to selecting the lush, healthy plants and the height of the trees to create a lot of vitality for offices and houses.

Fern

Very toxic plants should be grown indoors such as ferns that can suck aldehyde formic.

Plants grow long, erect cows in the head, leaves grow in the shape of two-headed, oval-shaped bark, soft and soft. The fern can absorb aldehyde formic gas.
