Pollution detection and treatment

Gas pollution is mainly caused by materials used in the decoration process and indoor furniture, including harmful gases such as formaldehyde, benzene, toluene, tvoc, and ammonia.

Overview of pollution detection and treatment: Decoration pollution: mainly gas pollution caused by materials used in the decoration process and indoor furniture, mainly including: formaldehyde, benzene, toluene, tvoc, ammonia and other harmful gases. There are many sources of indoor environmental pollution, and a considerable part of them are caused by improper materials used in the decoration process, including formaldehyde, benzene, xylene and other volatile organic gases. Nowadays, as people pay more attention to health, green environmental protection has become the primary consideration in home decoration. According to the survey, 2.8 million people worldwide die directly or indirectly from decoration pollution every year, and decoration pollution has been listed as one of the five most harmful environmental problems to the public. About 66% of a person’s life is spent at home, so poor indoor air environment will cause the most direct harm to human health. Among many decorative materials, toxic materials account for 68%, produce more than 300 volatile organic compounds (VOC), and can cause more than 30 diseases. Among the most vulnerable are the elderly and children, because they spend the longest time indoors. The most serious pollution from home decoration is formaldehyde. At present, major brands are launching green and healthy products, mainly to reduce the content of formaldehyde. However, according to reports, the release period of formaldehyde at home can be as long as 3 or 5 years, so people It is imperative to effectively reduce the harm caused by indoor formaldehyde. Decoration pollution detection and treatment: It is to detect these decoration pollution through various methods, and control them through relevant measures to reduce or even remove the harm of these decoration pollution to protect the health of the residents.

Misunderstandings in pollution detection and management: 1. Vinegar fumigation. Some consumers try to fumigate vinegar to remove the peculiar smell after home decoration. Experts pointed out that vinegar is an acidic substance that weakly neutralizes ammonia in the air, but does not react with other harmful components such as formaldehyde. 2. Place the pineapple. Some people think that putting a few pineapples in each room can eliminate the smell of paint, and put more in large rooms. Pineapple will volatilize its aroma to cover the smell, but it does not decompose to remove harmful substances. In addition, pineapple contains a lot of water, which can at most humidify after volatilization, and can dissolve harmful substances such as formaldehyde. Dry formaldehyde will volatilize again. 3. Excessive dependence on plants. Some ornamental plants can indeed absorb certain toxic gases. For example, plants that can absorb formaldehyde include cacti, spider plants, aloes, ivy, iron trees, chrysanthemums, etc.; and ivy, iron trees, and chrysanthemums have the ability to absorb benzene. , Can reduce benzene pollution. But the key is that their role is quite limited. In the face of the dense emission period of harmful gases after the renovation, their weak absorption effect not only cannot remove pollution to save the Lord, but even their own health cannot be guaranteed. A consumer once reported: “The flowers in my old house turned yellow within a few days after they were placed in the new house.” According to experts, this is probably caused by indoor pollution. 4. Place the tea roots. Some people even put dried tea roots after making tea in the closet and room, hoping to help remove the poison gas. As everyone knows, the effect of tea root in this respect is like dried leaves and toilet paper, with almost no absorption and decomposition. 5. Ozone generator. Using “ozone generator” as an air purification device is a bigger misunderstanding. Although ozone has sterilization and disinfection effects, it is also a medical conclusion that it is harmful to the human body. The use of ozone for disinfection can only be carried out in an environment where the human body is not in contact with it. It is obviously inappropriate to use it as room air purification. As for the use of ultraviolet emission sources as indoor disinfection equipment, foreign countries have long been eliminated, and Hong Kong and other places in my country have also eliminated them as early as 20 years ago. 6. Too superstitious about environmental protection building materials. The application of environmentally friendly building materials can help reduce harmful indoor gases. However: First of all: my country’s national standards for green building materials are not ideal. When setting environmentally friendly building materials standards, due to concerns about the low-level production status of most domestic building materials companies, some current standards can only be said It is barely enough, because a large number of companies will be closed if the standards are higher. The relevant industry regulatory authorities have tried to raise certain standards to move closer to international standards, but they gave up because of this. Second: Even if all environmentally-friendly building materials are used, the final air quality may exceed the standard. Because most environmentally friendly building materials only contain harmful substances and emit harmful gases below a certain standard, they do not contain harmful substances at all, and do not emit harmful gases at all. In addition, factors such as decoration design, room structure, and ventilation conditions are due to the superposition of harmful gases. As a result, there is still no guarantee that the indoor air quality will meet environmental protection standards after room decoration. 7. Completely rely on short-term ventilation treatment. Ventilation treatment, as a basic environmental protection measure, can improve indoor pollution, but because most harmful substances will be released slowly, as long as 3-15 years, it is not a problem that can be solved by ventilation in a few months. During its intensive emission period 1- Within 3 years, you will take a greater risk of disease and cancer; moreover, doors and windows must be closed in winter and summer in northern China, and the fresh air in most rooms and office buildings is not ideal, and the ventilation effect will be greatly reduced; in addition, taking formaldehyde as an example, it is divided There are three states: free, adsorbed, and bound. Only the free ventilation treatment can be eliminated, and it must be more than 4 times the normal wind speed. 8. Only consider environmental protection treatment when a strong irritating odor appears. Like human health, the indoor air environment also has three forms: healthy, sub-healthy, and diseased, and many harmful gases are colorless and tasteless. Just like treating diseases, the indoor air environment also requires prevention, health care, and treatment. Like the health doctor in the room, professional indoor environmental protection companies provide you with environmental protection treatment services to create a healthier indoor environment.

Necessity of pollution detection and treatment: Nowadays, human beings are facing the third environmental pollution mainly caused by “indoor air pollution” after “soot pollution” and “photochemical smog pollution”. American experts have found that there are more than 500 volatile organic compounds in indoor air, of which there are more than 20 carcinogens and more than 200 pathogenic viruses. The main hazards are: radon, formaldehyde, benzene, ammonia, esters, and trichloroethylene. A large number of shocking facts confirm that indoor air pollution has become an “invisible killer” that endangers human health, and it 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 can reach 100 times in special circumstances. Therefore, the United States has classified indoor air pollution as one of the five major environmental factors that endanger human health. The World Health Organization also lists indoor air pollution, high blood pressure, hypercholesterolemia, and obesity as the top 10 threats to human health. According to statistics, nearly half of the world’s people are exposed to indoor air pollution. Indoor environmental pollution has caused 35.7% of respiratory diseases, 22% of chronic lung diseases and 15% of bronchitis, bronchitis and lung cancer.
