1. Which of the formaldehyde hazards are serious?
A: Newly-decorated homes, offices, conference rooms, hotels, KTV rooms, furniture shopping malls, and building materials malls.
Prevent the harm of formaldehyde should pay attention to the following points:
i Note indoor air detection and purification. According to the degree of formaldehyde pollution in the indoor air, experts are requested to provide effective treatment plans, especially for families with elderly people, children, and allergic constitutions.
Ii Wardrobe made with artificial boards, such as formaldehyde is not cleared, must pay attention to use, try not to put underwear, pajamas and children's clothing inside.
Iii Take some effective decontamination measures in the room and furniture to reduce the harmful gases released by the furniture.
2. What are the hazards of formaldehyde?
A: Formaldehyde (chemical formula HCHO, molecular weight: 30.03, is a colorless gas with a strong pungent odor. It is easily soluble in water and alcohol ethers. It is gaseous at room temperature and usually occurs as an aqueous solution. Its 35%- -40% of the aqueous solution is called formalin, the boiling point of this solution is 19 ° C. Therefore, it evaporates easily at room temperature, and the volatilization rate increases with the increase of temperature. Formaldehyde is a highly toxic substance, toxic chemicals in our country are preferred. Ranked second in the control list, it has been identified by the World Health Organization as a carcinogenic and teratogenic substance, is a recognized source of allergy, and is also one of the potential strong mutagens.
Studies have shown that formaldehyde has a strong carcinogenic and cancer-promoting effect. A large number of documents have documented that the effects of formaldehyde poisoning on human health are mainly reflected in abnormal sense of smell, irritation, allergy, abnormal lung function, abnormal liver function, and abnormal immune function. When the concentration reaches 0.06-0.07 mg/m3 per cubic meter of air, children will experience slight asthma. When the indoor air reaches 0.1mg/m3, there is odor and discomfort; when it reaches 0.5mg/m3, it can stimulate eyes and cause tearing; reaching 0.6mg/m3 can cause throat discomfort or pain. At higher concentrations, it can cause nausea and vomiting, cough, chest tightness, wheezing, and even pulmonary edema; when it reaches 30 mg/m3, it will immediately cause death.
The hazards of long-term exposure to low-dose formaldehyde include: chronic respiratory disease, nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, gene mutations in the nucleus, cross-linking of DNA and cross-linking of DNA and proteins, and inhibition of DNA damage. Repair, pregnancy syndrome, newborn chromosomal abnormalities, and leukemia cause memory and mental decline in adolescents.
Of all the contacts, children and pregnant women are particularly sensitive to formaldehyde, and the harm is even greater. It is the main pollutant in decoration and furniture. The release period is as long as 3 to 15 years. When it encounters heat, it will be volatilized from the deep layer of the material and seriously pollute the environment. It has become a difficult problem to solve and it is the most dangerous to the elderly, children and pregnant women.
3. What are the sources of formaldehyde?
A: Formaldehyde can be contained in various artificial boards (particle board, fiberboard, plywood, etc.) due to the use of adhesives. The production of new furniture, wall and floor decoration, use adhesives. Wherever adhesives are used in large quantities, formaldehyde is always released. In addition, some chemical fiber carpets and paints also contain a certain amount of formaldehyde. Formaldehyde can also come from cosmetics. Cosmetics, detergents, insecticides, disinfectants, preservatives, printing inks, paper, textile fibers and many other chemical light industrial products.
4. What should I pay attention to before testing indoor air?
Answer: Doors and windows should be closed 12 hours in advance to ensure that the interior is closed and the drawers of the furniture are kept open. This will ensure accurate inspection results.
5, how to determine whether the indoor harmful gas is excessive?
a. When you get up early in the morning, you feel bored, nauseous, and even dizzy.
b. At home, people often have a cold, often with allergies, etc., and they are swarming. Children often cough, sneeze, and have decreased immunity.
c. Although I don't smoke, I often feel uncomfortable in my throat, foreign body sensation, poor breathing, and I feel sore throat, dry air, and work after work.
d. There is a disease in the family, and after leaving this environment, the symptoms have changed significantly and improved; newlyweds are not pregnant for a long time, and no reason can be found; pregnant women find fetal malformations under normal pregnancy.
e. In a new moving house or a newly renovated house, indoor plants are not easy to survive, leaves tend to yellow and wither; after the new move, domestic cats, dogs and even tropical fish somehow die.
f. Newly renovated homes and office rooms or new buyers have irritating odors such as pungent and harsh eyes, and the odors are persistent.
6. How long is the release period of formaldehyde?
A: Many newly renovated residents have air pollution in their homes. The main pollutants are benzene, toluene, xylene, and formaldehyde. The first three are volatile, and the most difficult to evaporate. The release period will be as long as 3 to 15 years. Improper household formaldehyde is even exceeding the standard. Formaldehyde has a great impact on human health, especially children's health, and can cause severe asthma and cancer.
7, environmental protection furniture is really green? Is there any pollution?
A: Actually, "green building materials" and "environmental protection materials" do not mean that there is no pollution, but that their pollution is lower than the national standards. If the formaldehyde emission of some plates is less than 0.15 milligrams per cubic meter, it can be called “green building materialsâ€. In other words, under the current production level and conditions, green building materials are not completely free from harmful substances, but they are harmful. Material control is within the minimum standard value.
8. Will there be pollution after the new house is put in place for a period of time after it has been renovated?
A: Formaldehyde exists in three states: free state, adsorption state, and binding state. Formaldehyde can only be eliminated by ventilation if it is released in a free state. Studies have shown that the release period of indoor formaldehyde is generally 3 to 15 years, which means that ventilation after the decoration can not completely remove indoor formaldehyde, and can only temporarily reduce the effect of formaldehyde concentration.
9. What are the main sources of indoor air pollution?
A: More than 80% of people's lives are spent indoors. Therefore, the quality of indoor environment is crucial to human health. Indoor pollution is mainly caused by interior decoration and has become a special disaster in contemporary cities. Nearly 70% of diseases are caused by indoor air pollution.
The most common types of contamination are flaws (antifreeze used in construction), formaldehyde (slabs, large core boards, medium density boards, particle board, etc.), benzene (paints, coatings, various adhesives), ammonia (affixed to Wall coverings, wallpapers, chemical fiber carpets, waterproof materials, etc.), radioactive materials (natural granite, marble, tiles, etc.), tvoc (artificial, foam insulation, plastic sheeting, and other building materials, asbestos).
10, no smell is equivalent to no formaldehyde?
A: At the moment, people often fall into such a misunderstanding: Indoors, you can rely on the smell to identify formaldehyde and other pollutants. As long as there is no taste in the house, it is safe. In fact, this is a fatal mistake. Formaldehyde is a kind of irritating gas. If people feel obvious irritation, such as tears, coughs and other adverse reactions, it means that formaldehyde has exceeded the standard multiple times. However, if the indoor formaldehyde content is slightly exceeded, or even exceeds the standard 2-3 times, the normal population is hardly noticeable. At this time, it is not scientific to rely on the nose to distinguish the pollution completely. 11, What is formaldehyde? What are the hazards of formaldehyde?
A: Formaldehyde, commonly known as formalin, is a colorless, pungent irritant gas. Its 35% to 40% aqueous solution is known as formalin. Formaldehyde is a poison of the original pulp, which can bind to proteins. After inhaling a high concentration of formaldehyde, severe respiratory tract irritation, edema, eye irritation, headache, and bronchial asthma can also occur. Direct contact with formaldehyde on the skin can cause dermatitis, pigmentation, and necrosis. Frequent inhalation of small amounts of formaldehyde, can cause chronic poisoning, mucosal congestion, skin irritation, allergic dermatitis, nail keratinization and fragility, finger bed pain, long-term inhalation of pregnant women may cause neonatal deformity, and even death, men can be long-term inhalation Cause sperm deformity, death, sexual function decline, serious can lead to loss of reproductive ability, systemic symptoms include headache, fatigue, appetite, palpitations, insomnia, weight loss and autonomic disorders.
12, decoration wallpaper also contains formaldehyde?
A: Consumers should be beautiful when shopping for wallpapers, and they should be healthier. Wallpaper can also cause indoor environmental pollution. Because of the different composition of the wallpaper, its influence is also different. Some chemical fiber textile wallpapers can release harmful gases such as formaldehyde due to the raw materials they make and the materials used in the production process. In addition, due to its beautiful appearance, low cost, durability, easy cleaning, long service life, convenient construction, etc., the plastic wallpaper has been developed very rapidly, and its use has been continuously popularized. During the use of this wallpaper, due to the aging decomposition of unpolymerized monomers and plastics contained therein, a large amount of organic substances can be released into the room, such as formaldehyde, vinyl chloride, benzene, toluene, xylene, ethylbenzene and other serious polluted indoor. air.
13. What are the national standards for indoor environmental testing?
Answer: 1, "indoor air quality standards" (GB/T1883-2002): Formaldehyde ≤ 0.10, benzene ≤ 0.11, TVOC ≤ 0.60;

14, formaldehyde poisoning how to do?
A: 1. Mild poisoning patients, it is recommended that he immediately away from the environment containing a lot of formaldehyde, replace all contaminated clothing, and timely with a lot of water for systemic cleaning, preferably with soapy water or 2 % sodium bicarbonate solution. Of course, if it is the eyes, you have to use clear water.
2. Moderate poisoning patients, you can try to inhale 0.1% of the diluted ammonia, if you want to quickly remove the symptoms of throat edema, pulmonary edema due to formaldehyde poisoning, it is recommended to use adequate glucocorticoids.
3. If the patient is exposed to a large amount of formaldehyde in the short term and affects the respiratory tract, then it must be observed for 2-3 days to avoid aggravation of the condition caused by exercise.
4. To maintain airway patency, some bronchial spasms can be used, defoamers, tracheotomy if necessary.
5. Symptomatic treatment, to avoid infection, prevent complications.
15, the seven errors in the decoration process?
A: First, the interior design only considers whether the design is beautiful or luxurious, but it does not care about the indoor function and safety as well as excessive formaldehyde.
Second, if the interior decoration when the special selection of expensive, high-end decoration materials, then, after the installation will certainly appear indoor formaldehyde pollution;
Third, feel that looking for those large-scale renovation companies to decorate must be within the national standard, and will soon be able to stay;
Fourth, after the decoration feels good to use formaldehyde scavenger to remove formaldehyde, or use pineapple peel, orange peel, etc. to cover up the irritation odor of formaldehyde to be all right;
5. If you buy a lot of so-called environmental protection materials, you will feel that there will be no formaldehyde pollution;
6. It is normal to think that the house has just been decorated and tasted. It will be better after a while;
Seventh, when I was admitted into the room for some time, I discovered that the odor was there. I thought that the formaldehyde had been cleared and it was fine.
16, what is the CMA certification A: China Metrology Accreditation referred to as "CMA", English named "China Metrology Accreditation". According to the provisions of the People's Republic of China Measurement Law, the metrological administrative department of the people's government at or above the provincial level carries out a comprehensive certification and evaluation of the detection capabilities and reliability of the testing organizations. This certification target is all product quality supervision and inspection agencies and other types of laboratories that provide fair data to the society, such as various product quality supervision and inspection stations, environmental monitoring stations, and disease prevention and control centers. The testing organization that has obtained the measurement certification certificate shall be allowed to use the CMA mark on the inspection report; the inspection report with the CMA mark may be used for product quality evaluation, results and forensic examination, trade transactions, etc. It has legal effect and is an arbitration and judicial body. The basis of acceptance. The CMA is generally only for third-party laboratories, but also includes a small number of specific second-party laboratories. The scope of CMA is relatively small. He is generally together with censorship accreditation and is only qualified after the authorization of the government. Popularly speaking, the report covering the CMA seal has the legal effect recognized by the state and can be used to dispute the indoor environment. It is necessary to file a lawsuit against a unit that causes indoor environmental pollution (such as a decoration company).
17. The five basic standards for living in modern homes are: 1. Sunlight can kill microorganisms in the air and improve the body's immunity. Experts believe that in order to maintain human health and normal development, the daily sunshine hours must be more than 2 hours a day.
2. Lighting. Refers to the natural light that can be obtained in a house. The ratio of the effective area of ​​a typical window to the floor area of ​​a room should be greater than 1:15. ?
3. The indoor net height must not be less than 2.8 meters. This standard is regulated by the Civil Building Design Quota. For occupants, a suitable net height gives people a good sense of space, and a net high or low will make people feel depressed. Experiments show that when the net height of the room is lower than 2.55 meters, the indoor carbon dioxide concentration is high, which has a significant impact on the indoor air quality. ?
4. Microclimate: In order to keep the sanitation of the homes in a good condition, it is generally required that the room temperature in winter is not lower than 12 degrees Celsius, and that in summer is not higher than 30 degrees Celsius; the indoor relative humidity is not more than 65%; the summer wind speed is not less than 0.15 meters per second; Not more than 0.3 meters/second.
5. Air clarity. It means that the total amount of certain harmful gases, metabolites, fly ash, and bacteria in the air in HOS cannot exceed a certain level. These harmful gases mainly include carbon dioxide, sulfur dioxide, helium, formaldehyde, and volatile benzene.
18, the largest deadly killer of children's room, hidden in your home A: When the modern family decoration in the new home, many parents always like to put the baby's cabin is cute and beautiful. However, more and more experience shows that inappropriate decoration materials or unreasonable furniture arrangements may affect his healthy growth.
In addition to pursuing the beauty of the decoration design program, we should put more careful thoughts on how to create a healthy living environment for the baby. The formaldehyde in the decoration materials can be said to be the decoration of the children's room. The first killer. Excessive formaldehyde has more serious effects on children's hematopoietic organs than adults. Children have hematological characteristics different from adults, their hematopoietic function is unstable, hematopoietic reserve is poor, hematopoietic organs are easily infected, and hematopoietic organs are prone to nutritional deficiencies. At the same time, formaldehyde has become a major cause of childhood asthma, leukemia and other incurable diseases.
It can be seen that finding a professional in addition to formaldehyde companies in modern family life is essential for formaldehyde detection and management.
A: Newly-decorated homes, offices, conference rooms, hotels, KTV rooms, furniture shopping malls, and building materials malls.
Prevent the harm of formaldehyde should pay attention to the following points:
i Note indoor air detection and purification. According to the degree of formaldehyde pollution in the indoor air, experts are requested to provide effective treatment plans, especially for families with elderly people, children, and allergic constitutions.
