Indoor air pollution means that the amount of air pollutants entering the room exceeds the self-purification capacity of the indoor environment, resulting in a decrease and deterioration of the air quality inside the room, which directly or indirectly affects people, and is called indoor air pollution. Now, "human beings are facing the third environmental pollution mainly "indoor air pollution" after "soot pollution" and "photochemical smog pollution". US experts have found that there are more than 500 volatile organic compounds in indoor air. There are more than 20 kinds of carcinogens and more than 200 kinds of pathogenic viruses. The main hazards are: strontium, formaldehyde, benzene, ammonia and esters, trichloroethylene, etc. A lot of shocking facts confirm that indoor air pollution has become The “invisible killer” that endangers human health has also become a common concern of all countries in the world. Studies have shown that indoor air pollution is 2-5 times more serious than outdoor air and 100 times in special cases.


Indoor air pollutants mainly invade the human body through three ways, which are harmful to human health, that is, absorbed through the respiratory tract, absorbed through the skin and absorbed through the digestive tract. The main indoor pollutants are as follows:


1, PM2.5 - after being inhaled into the human body, it will enter the bronchioles and even the alveoli, and can enter the circulatory system through the blood gas barrier, causing diseases including asthma, bronchitis and cardiovascular diseases.


2, TVOC - According to research, when volatile organic compounds reach a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short time. In severe cases, convulsions and coma will occur, and people's liver, kidney and brain will be harmed. And the nervous system, causing serious consequences such as memory loss.


3. Indoor combustion or heating mainly refers to the heating of various fuels and the heating of food and food during cooking. Mainly include: sulfur dioxide, nitrogen oxides, carbon monoxide, carbon dioxide, hydrocarbons (including carcinogenic polycyclic aromatic hydrocarbons such as phenylpropanoid) and suspended particulate matter.


4. Indoor activities are a large amount of metabolic waste that is not discharged from the human body, and droplets sprayed during conversations are the main sources of indoor air pollution. Smoking is an important source of harmful substances. Tobacco smoke contains at least 3,800 components, of which no less than 44 are carcinogens.


5. Indoor building materials: This is the main source of indoor air pollution. For example, paints, coatings, plywood, particleboard, foam filling materials, plastic veneers, etc. all contain volatile organic compounds such as formaldehyde, benzene, toluene, ethanol, chloroform, etc.; building materials such as bricks and slate contain mother elements such as radium and thallium. At higher levels, the concentration of indoor radon will increase significantly, and its carcinogenicity is receiving more and more attention.


Then we have to control the source of pollution as follows:


1. Interior decoration and addition of furniture, care should be taken to avoid the use of unqualified products with excessive toxic substances; maintain good personal hygiene habits such as bathing, spitting, etc.; often wash clothes, bedding, etc.; often clean air conditioning system; Pets; selectively raise flowers; block mosquitoes from entering the room; use pesticides, detergents, paints and other chemicals carefully; control indoor humidity, reduce mold and bacteria growth; clean up domestic garbage and waste materials in time.

2. The ventilation system is operated by the main engine to introduce fresh air from the outside, and after filtering, it is sent to each room through the air supply duct; the dirty air is discharged from the exhaust main unit through the exhaust duct, thereby creating a good living environment. .


The friends who have seen it now, do not know a lot about the pollution in our room, how to control the indoor pollution is good! Xiaobian here hope that everyone will have a nice, comfortable interior.
