Purification function of flowers and plants

Society is developing and life is improving, but the "killers" that endanger human health can be seen everywhere, and are getting closer and closer to human life. Even in the home where you live for the longest time and have the most contact, there is environmental pollution everywhere. According to the data, the place with the highest density of dust and gas is sometimes in the residents' homes, and the air pollution in kitchens and rooms is sometimes ten times, hundreds of times or even higher than the outdoor pollution in general.

I. what is the pollution of the family environment?

1. Pollution caused by construction, decoration and decoration materials

The concrete used in buildings is added with additives such as antifreeze, expansive agent and early strength agent, which can improve the solidification rate and prevent low temperature. These additives contain a large amount of ammonia, which is slowly released from the wall with the change of temperature and humidity and other environmental factors. In the process of interior decoration and the production of all kinds of furniture, all kinds of plywood, veneer, wood chip board, reinforced and synthetic flooring are widely used. The free formaldehyde contained in the binder used in these floors will be gradually released after decoration and in the process of furniture use. According to the random inspection of interior decoration and decoration materials conducted by the national health and environmental protection departments, it is found that more than 60% of the materials are poisonous gas pollution. These materials are one of the main sources of indoor environmental pollution and can cause a variety of diseases of respiratory tract, digestive tract and other organs.

two。 Pollution caused by volatile substances released from furniture

At present, the furniture materials on the market are not well raised, and some furniture and their production materials contain formaldehyde, benzene and other pollutants. According to the relevant data of the Indoor Environment testing Center of China Interior Decoration Association, the indoor air pollution caused by furniture has become another major source of pollution after building pollution and decoration pollution. Some experts believe that indoor decoration materials, such as plywood, Blockboard, medium density fibreboard and create a board and other artificial panels for indoor air pollution is quite large.

The pollution caused by the use of daily necessities people also unwittingly "produce" a large amount of toxic gases in their daily life. For example, gas combustion in kitchens and bathrooms, cooking fumes and shower heating all produce a large number of toxic pollutants such as carbon dioxide, ammonia oxides, sulfur dioxide, respirable particulates, halogenated hydrocarbons, polycyclic aromatic hydrocarbons, hair care products such as mousse and hair gel, air fresheners and cleaners sometimes produce toxic and harmful chemical gases such as toluene, p-xylene and chlorinated hydrocarbons. The use of a large number of air conditioners in cities is also the source of indoor pollution. When the air conditioners are in operation, due to the high internal humidity and suitable temperature, it is the gathering place of many bacteria. Air conditioners exchange indoor and outdoor air, but also bring a large number of bacteria into the indoor, resulting in the biological pollution of the indoor environment.

3. Pollution caused by the surrounding environment

In addition, the surrounding environment of the home has also brought some pollution to the interior. The surrounding chemical plants, refineries, construction, automobile driving and so on have released a large amount of ammonia, ammonia oxide, sulfur dioxide, carbon monoxide, chloride and other toxic gases as well as all kinds of dust. These toxic and harmful gases and dust float into the home with the atmosphere, and they are also important "accomplices" of indoor environmental pollution.

Second, how to purify the household environment by flowers and plants

It has long been known that plants can absorb carbon dioxide during photosynthesis, but in addition, many plants also absorb other carbon-containing substances, including volatile organic compounds that are harmful to humans. The study found that every 10 cubic meters indoor placed a 1.2 to 1.5 meters high living green plants, can effectively absorb carbon dioxide, carbon monoxide, formaldehyde, benzene and other harmful gases. In addition, some plants can also convert harmful chemicals into plant nutrients. Therefore, green plants have a good purification effect on indoor air pollution.

1. Absorb poisonous gases

Many plants have the ability to absorb poisonous gases. For example, tiger tail orchid can remove a large amount of formaldehyde, benzene and vinyl chloride and other toxic gases; hanging orchid can "swallow" 95% of carbon monoxide, 85% formaldehyde, 80% benzene, 50% trichloroethylene; in addition, Milan, geranium, Yu Meiren, cycad and so on have the function of absorbing harmful gases and anti-pollution.

two。 Adsorbed dust

Parthenocissus parthenocissus, wax plum, hibiscus, palm, Fusang and many other plants with large leaf area and furry leaf surface have a strong ability to absorb dust and can effectively reduce the particulate pollutants in indoor air.

3. Release of germicidal substances

Some plants, such as cactus, cactus, arrow lotus, orchid, etc., not only do not exhale carbon dioxide at night, but also absorb carbon dioxide, purify the air, but also produce oxygen and release germicidal substances, so as to achieve germicidal effect.

4. Adjust indoor gas balance, increase air humidity and increase indoor air comfort

African Violet, Cymbidium, Phalaenopsis, Carnation and other flowers and plants can not only absorb carbon dioxide and release oxygen, but also increase air humidity and negative ion concentration, make the air fresh and enhance comfort.
