In 1989 NASA launched an investigation to determine which are the best indoor plants to purify the air. The scientists discovered that the air inside contains constantly particles of harmful organic compounds: trichlorethylene, benzene, ammonia and others. Because indoor plants have the ability to neutralize up to 85% of the air pollution in a room, specialists recommend putting them in different rooms to, in such a way, purify the air in an ecological way.
The air inside contains five harmful elements:
- Formaldehyde. It is found in furniture made of chipboard, carpets, upholstery materials, tobacco smoke, plastic dishes, gas. It produces allergic reactions, irritations, asthma, cutaneous diseases.
- Trichlorethylene. It is found in cleaners for carpets and fabrics, chlorinated water, cartridges for printers, paints and varnishes. Trichlorethylene is a strong carcinogen that causes eye and skin irritation, affects the liver and kidneys, and causes psychomotor agitation.
- Benzene. It is found in tobacco smoke, detergents, including toilet soap, paints and varnishes, rubber products for cleaning. It is a carcinogen that is capable of causing leukemia, it accumulates in adipose tissue
- causing excitement, similar to alcoholic excitement, difficulty breathing and seizures; as well as decreases blood pressure
- Ammonia. It is found in computers, tobacco smoke and industrial agents for cleaning. Causes the sensation of dry garter, cough, pains in the chest, causes inflammation of the larynx and lungs.
- Xylene. With this element many types of plastics, paints, varnishes and glues are produced; it is also contained in vehicle exhaust gases, leather products and tobacco smoke. It causes irritation in the skin, respiratory tract and mucous membrane of the eye.
Although you are not very aware, plants play a role that we sometimes overlook: they are ideal for purifying the air from the environment. As you read it, apart from being cheerful, colorful and adding a touch of color to any environment, they are perfect for dealing with air pollution, according to NASA.
However, not all do it with the same efficiency. When filtering polluting substances, some are better than others. Before that, in 1989, NASA conducted a study to determine which are the most convenient to fulfill this mission in a closed space.
To carry out the research, the various contaminants present in the air, the characteristics of the plants, and the ease of obtaining them in the market were taken into account. Also, the most common pollutants that the plants are responsible for filtering are benzene, xylene, ammonia, trichlorethylene and formaldehyde, according to the study.
A round of applause to these people who day by day congratulate us with their beautiful content. Congratulations and good wishes.
