Indoor decoration pollution detection method
The harmful gas represented by formaldehyde has always been a killer in decoration pollution and has been poisoning our lives. Many chemicals used in furniture and building materials have been proved to release formaldehyde and other analogues, which are not only uncomfortable, but also carcinogenic and mutagenic. Therefore, indoor decoration pollution detection is a very important thing.
At present, the detection method of decoration pollution is mainly to invite professional indoor decoration pollution detection companies to carry out inspection, and the price of one inspection is between 500- 1000 RMB, which is still relatively expensive. Such an indoor decoration pollution detection company basically has two detection objects: formaldehyde and benzene. If you want to detect other harmful substances, you have to pay extra, and sometimes you can't detect the items you want to check.
If we want to say a relatively simple decoration pollution detection method in the family, there are formaldehyde adsorbent particles that will change color on the market now. Buy some bags and put them in different places at home to see the degree of discoloration. The darker it is, the more serious the formaldehyde pollution is. Measures such as ventilation can be taken to remove it.

Another way to detect decoration pollution is to use green plants. Plants are alive like people, and some plants are more sensitive to some gas environments and have unique performances. If the environment is good, you will grow well, and if the environment is bad, it will reflect illness. If the indoor air conditions are poor, green plants will generally have obvious pathological changes, such as yellow leaves, white spots, thin plants and other abnormal symptoms.
The most direct method of indoor decoration pollution detection is your sense of smell. Although some harmful pollutants are odorless, if you smell something wrong, it means that the indoor pollution concentration is already very high, so you need to open the window for air immediately. If anorexia, poor sleep, headache and vomiting occur, it may also be the cause of poor indoor air quality, which needs immediate attention.

What are the indoor decoration pollution?
Experts said that the indoor air pollution sources in China mainly come from three aspects: the pollution caused by the building itself, such as the radioactive pollutants produced by some building materials due to the high radioactive background of raw materials; Pollution caused by indoor decoration materials and techniques, such as plates, chemical fiber carpets, wallpaper, etc. , especially low-grade materials, is more serious; Pollution caused by furniture and household appliances, such as formaldehyde released by panel furniture and benzene pollution caused by glue spraying on fabric sofas. Scientific research shows that the above substances contain more than 300 kinds of volatile organic compounds, five of which are the most important and harmful:
Radon-The latest research published by the World Health Organization shows that radon has become the second largest cause of lung cancer after smoking. Professor Zhi, director of the lung cancer diagnosis and treatment center of Capital Medical University, said that radon is a natural radioactive gas, colorless and tasteless, just like "invisible smoke". Its main hiding places are granite and ceramic products such as tiles and sanitary ware. The average radon content per cubic meter increased 100 baker, and the risk of lung cancer increased 16%. In the United States, about 60 people die of radon every day, which exceeds the number of AIDS deaths.
Formaldehyde-mainly comes from plates, such as wood-based panels, sandwich panels, adhesives, etc. Long-term contact can cause cancer of nasal cavity, oral cavity, nasopharynx, throat, skin and digestive tract; Low-dose exposure can lead to chronic respiratory diseases, pregnancy syndrome and even nasopharyngeal carcinoma.
Ammonia-mainly from concrete additives and interior decoration materials. Ammonia gas is easily soluble in water, which has a rapid effect on eyes, throat and upper respiratory tract and is highly irritating. Tears, sore throat, cough, chest tightness, dyspnea, dizziness, vomiting, fatigue, etc. It will appear after inhaling a large amount of ammonia for a short time. Especially in winter construction, it exists in antifreeze in large quantities.

Total volatile organic compounds-mainly from furniture, wallpaper, etc. It can cause immune level disorder, affect the function of central nervous system, appear dizziness, headache, lethargy, chest tightness and other symptoms, and may also affect the digestive system, leading to loss of appetite, nausea and so on. In severe cases, it will damage the liver and hematopoietic system.
Benzene-mainly from paints, coatings, adhesives, wallpapers, carpets, synthetic fibers, detergents and solvents. Benzene has a special smell, but it is a strong carcinogen. Long-term inhalation will destroy the human circulatory system and hematopoietic function, leading to leukemia.
Will these five substances really make decoration pollution an "invisible killer"? Zhi said that indoor pollution caused by decoration materials is indeed an important cause of cancer. Toxic substances in the decoration may be related to leukemia.
The above is about indoor decoration pollution detection methods and what indoor decoration pollution has. Indoor decoration pollution is inevitable for us. If there is a house decoration, there will be decoration pollution, but it is just a matter of how much decoration pollution. Therefore, we should try our best to reduce indoor decoration pollution. Of course, the first step is to start with decoration pollution detection.
