The smell of furniture in the new house is suffocating. How to get rid of it?

Furniture pollution should be paid attention to. Furniture smells, mainly caused by pollutants such as formaldehyde, benzene and TVOC.

Harm of benzene

Benzene is a colorless gas with special fragrance, which has been identified as a strong carcinogen by the World Health Organization. Benzene is the main reason for the increase of childhood leukemia patients in recent years. According to the survey data, 90% of children with leukemia in cities have done interior decoration within one year.

Inhalation of high concentration benzene in a short period of time will have the anesthetic effect of the central nervous system, ranging from dizziness, headache, nausea, vomiting, chest tightness and fatigue, to coma or even death due to respiratory and circulatory failure! If exposed to a certain concentration of benzene for a long time, it will cause chronic poisoning, such as headache, insomnia, listlessness, memory loss and other neurasthenia symptoms.

Harm of formaldehyde

Formaldehyde is a colorless and strongly irritating gas, which has been identified as carcinogenic and teratogenic by the World Health Organization. Formaldehyde pollution can cause eye tears, hyperemia and inflammation of cornea and conjunctiva, skin allergy, nasopharyngeal discomfort, cough, acute and chronic bronchitis and other respiratory diseases, and can also cause nausea, vomiting and gastrointestinal dysfunction! Severe cases can also cause persistent headache, pneumonia, pulmonary edema, loss of appetite, and even death.

Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, eye diseases, irregular menstruation and disorder in women, pregnancy syndrome, neonatal malformation and mental depression. In addition, it can also promote the physical decline of newborns and cause heart disease in children. According to the investigation of American medical department, formaldehyde pollution is the main reason for the increase of asthma in children aged 3-5.

Harm of ammonia

Ammonia is a colorless gas with a strong pungent smell, which is lighter than air (specific gravity 0.5). Ammonia is an alkaline substance, which has corrosive and irritating effects on the skin tissue it contacts. It can absorb moisture in skin tissue, denature tissue protein, saponify tissue fat and destroy cell membrane structure. When the concentration is too high, in addition to corrosion, it can also cause cardiac arrest and respiratory arrest through the reverse action of trigeminal nerve endings. Ammonia is usually inhaled into alveoli in the form of gas. After ammonia is inhaled into the lungs, it can easily enter the blood through alveoli and combine with hemoglobin, destroying the oxygen transport function. The solubility of ammonia is extremely high, so it mainly stimulates and corrodes the upper respiratory tract of animals or human bodies, and weakens the resistance of human bodies to diseases. A small amount of ammonia is neutralized by carbon dioxide, and the remaining small amount of ammonia is absorbed into the blood, which can be excreted with sweat, urine or respiratory tract. Some people will have symptoms such as skin pigmentation or finger ulcers when they are exposed to ammonia for a long time; After inhaling a large amount of ammonia in a short time, there may be symptoms such as tears, sore throat, hoarseness, cough, bloodshot sputum, chest tightness, dyspnea, dizziness, headache, nausea, vomiting and fatigue. In severe cases, pulmonary edema, adult respiratory distress syndrome and respiratory irritation may occur. Therefore, alkaline substances do deeper and more serious damage to tissues than acidic substances.

The harm of TVOC

Volatile organic compounds (TVOC) mostly refer to compounds with boiling point of 50-250. According to their different chemical structures, TVOC can be further divided into eight categories. Alkanes, aromatics, olefins, halogenated hydrocarbons, aldehydes, ketones and others. 50-300 kinds of volatile organic compounds can be seen in non-industrial indoor environment. They all appear in trace and measured levels, and each compound rarely exceeds the level of 50 mg/m3. TVOC can cause the imbalance of immune level, affect the function of central nervous system, and have symptoms such as dizziness, headache, drowsiness, fatigue and chest tightness. It may also affect the digestive system, leading to loss of appetite and nausea. Severe cases may damage the liver and hematopoietic system, leading to neurotoxicity.

Specific manifestations and cases of indoor pollution

1, tachycardia syndrome

Symptoms: After buying new furniture, the smell at home is unacceptable and causes physical illness.

Case: 65438+At the end of February 2000, Ms. Li ordered a set of fabric sofas in Fu Park Jung Su Furniture City at a price of 3300 yuan. No quality problems were found on the surface of the sofa, but it was found that the sofa gave off an unpleasant smell after being placed indoors for a short time. Ms. Li, who is retired at home, dare not stay at home for a long time. As soon as she entered the room, she felt breathless, breathless, and even woke up at night. What makes Ms. Li even more uncomfortable is that in a few days, Ms. Li added another tachycardia problem, jumping to 100 in one minute, but strangely, when she arrived at the hospital for examination, her heartbeat dropped to 80. On June 5438+08, the air quality was tested by the testing center, and it was found that the volatilization amount of benzene in the adhesive used on the sofa sponge was as high as 20 ml per cubic meter.

g？ It is 8.3 times higher than the relevant national standards, so it is no wonder that Li Can can't stand it.

Prescription: formaldehyde contains pollutants in furniture, and then ventilation.

2. Smoking-like syndrome

Symptoms: Although I don't smoke and rarely come into contact with smoking environment, I often feel uncomfortable throat, foreign body sensation and poor breathing.

Case: 1998, Mr. Chen Ying asked the decoration company to carry out decoration. After the completion of the project, Mr. Chen felt that the indoor smell was pungent, causing sore throat, cough, bitter eyes and tears, and he could not live. In addition, Mr. Chen's throat disease has worsened. After hospital examination, it was found to be "laryngeal papilloma" and surgery was performed in Union Medical College Hospital. He asked the testing unit to test his residence. After the room was closed for 24 hours according to regulations, experts from the testing center conducted a indoor air testing with tears (caused by indoor harmful gases). Results The formaldehyde content in the bedroom was as high as 0/.56 mg per cubic meter/kloc-0, which was 9.5 times higher than the national standard/kloc-0.

Prescription: Indoor harmful decoration parts, especially inferior wood-based panels, should be sealed with formaldehyde.

3. Infant syndrome

Symptoms: Children at home often cough and sneeze, and their immunity decreases. The children in the newly renovated house are unwilling to go home.

Case: Ms. Wu, who lives in Liangxiang, Beijing, completed the renovation in May 2000. At that time, the smell in the room was very strong, but as she was about to give her old house to others, she moved in immediately after the renovation. Results From September, Ms. Wu's 3-year-old son began to get sick, starting with pharyngitis and chronic asthma, and gradually his immunity declined and his body resistance weakened. He didn't stay for a few days in a winter.

Kindergarten. The chubby child actually became a little smaller after half a year, and I couldn't find the reason after going to the hospital many times. Recently, Ms. Wu saw a report about the injury caused by the indoor environment. She felt that the child's body was related to the indoor environment at home, so she quickly went to an expert for testing. After field sampling and laboratory analysis, it was found that Ms. Wu's room at 10 was being renovated.

A few months later, the indoor formaldehyde per cubic meter of air reached 0.36 mg, more than 4 times the national standard!

Prescription: Pay attention to the use of harmless materials in the decoration of children's rooms; Let the children live in after the decoration smell is completely clean; Effective indoor air testing and governance.

4. Popular dermatosis syndrome

Symptoms: family members often have skin allergies and other problems, and they are mass-produced.

Case: Ms. Chen, who lives in Chengshou Temple, pays great attention to the indoor environment when decorating, and there is basically no pollution indoors. I didn't expect that there was something wrong with the whole kitchen she ordered for more than 3 thousand yuan. The strong pungent smell makes the hostess afraid to cook in the kitchen, because if she stays a little longer, her neck and face will have an allergic reaction, which will be swollen and itchy, and so will her relatives.

Prescription: Only by removing the pollution source can the symptoms of the whole family be cured.

5. Family group disease syndrome

Symptoms: My family got a disease, and after leaving this environment, the symptoms changed and improved obviously.

Case: 1997 Consumer Liu Zhongyi 1 bought a house with a square meter of Huade Apartment 1 Building 702 180. Shortly after moving in, he found that the indoor air pollution was serious, and Mr. Liu's family felt unwell. Mr. Liu had allergic rhinitis, and it got worse after he moved in. His son was diagnosed as pharyngitis by the hospital. After that, please ask the testing department to conduct indoor air quality testing.

The results show that ammonia and formaldehyde in indoor air seriously exceed the standard, and the highest ammonia exceeds the national air standard for residential areas 14.2 times, with an average of 9.36 times. The highest formaldehyde exceeded the standard 1.5 times, and the average exceeded the standard 1.05 times.

Prescription: Indoor environmental pollution is not only decoration, but also building materials. Before buying a house, it is best to check or control the air in the house before moving in.

6. Infertility syndrome

Symptoms: Newly-married couples are not pregnant for a long time and can't find out the reason.

Case: On the afternoon of May 10, 2000, a resident who lives in Xueyuan Road angrily smashed his cuckoo green granite. With the help of radioactive detection experts from the University of Geology, the young man finally found out the cause of his wife's infertility: the murderer who killed his sperm was actually the granite that decorated the toilet two years ago. It turns out that the young man's wife has been infertile since she got married, and finally it was identified by the hospital as his.

Responsibility, saying that his sperm survival rate is extremely low, the doctor said that it may be due to excessive radioactive radiation exposure. In his suite with one room and one living room, granite called cuckoo green is used in the hall and bathroom. Through the on-site inspection of stone, the rhododendron green stone far exceeds the national indoor stone use standard, and the radioactive element content is very uneven, and the radioactivity at individual points is very uneven.

The level is quite high, some measuring points are Grade C, and some measuring points are Grade C or above, so they cannot be used on the external walls of buildings. Living in such a highly radioactive radiation environment for a long time, of course, may cause harm to the body.

Prescription: Strong radioactivity will not only lead to infertility, but also cause cancer symptoms. Therefore, when using natural stone and its products in home decoration, we must pay attention to the radioactive problem.

7. Fetal malformation syndrome

Symptoms: Pregnant women find fetal malformation in normal pregnancy.

Case: The doctor of Chaoyang District Maternal and Child Health Hospital in Beijing induced labor and gave birth to a deformed baby girl for Li Rongju, a pregnant woman who came to work in Beijing from other places. This five-month-old fetus has no stomach. What's more peculiar is that her mouth protrudes sharply, even higher than her nose, and there is a small hole in her lower jaw. A few days ago, Li Rongju came to the hospital for a B-ultrasound examination. When the doctor found that the fetus was abnormal, he suggested introducing it.

It turns out that the doctor's diagnosis is correct. According to the pregnant woman herself, she once gave birth to a child and was in normal health, but her husband is a painter who has been engaged in interior decoration all the year round, and the place where she works has just been renovated. Therefore, doctors in the Maternal and Child Health Hospital speculated that the pregnant woman was probably exposed to toxic and harmful substances during pregnancy.

Fetal malformation

Prescription: Dr. Zheng, an expert in maternal and child health care, specially reminds newlyweds not to touch toxic and harmful substances before and during pregnancy, and to go to the hospital regularly after pregnancy.

8. Plant wilt syndrome

Symptoms: After the new move or renovation, indoor plants are not easy to survive, and their leaves are easy to turn yellow and wither, especially some plants with the strongest vitality are difficult to grow normally.

Case: On a Monday morning in 2000 1 year1month, employees of a company working in a high-end office building in Xuanwumen excitedly walked into the newly renovated office. However, as soon as they opened the office door, everyone was shocked by what they saw. I saw that in the office of more than 300 square meters, all kinds of flowers and trees withered after work on weekends, even the flower arrangement on their desks was no exception ... Many employees felt abnormal indoor smell, and some even had symptoms such as respiratory irritation, shortness of breath, chest tightness and dizziness. According to the company's office indoor air testing, three of the five indoor air items do not meet the relevant national standards, among which formaldehyde exceeds the standard by 8 times!

Prescription: Abnormal death of plants is also an important signal of indoor air pollution. If your family has such a problem, you should look for the reason from the decoration pollution.

9. Pet death syndrome

Symptoms: After the new move, the family's pet cats, dogs and even tropical fish died inexplicably, and so did the neighbors.

Case: A strange thing happened in a new high-rise residential building somewhere. A few days after residents moved to their new homes, all their pets, kittens and puppies died inexplicably, and they couldn't find the reason after many searches. Later, experts from the testing center were invited for on-site testing, and it was found that the indoor radon content was particularly high, mainly from the slag bricks used in local buildings.

After a newly renovated resident in Beijing moved in, the smell in the room was pungent, not only the flowers and plants that had been raised for many years turned yellow, but also the tropical fish that had been raised at home for many years died one by one. After testing by experts in the testing center, harmful gases in indoor air seriously exceeded the standard.

Prescription: Pets are sometimes more sensitive to indoor air pollution than people. Especially for colorless, odorless and radioactive radon gas. This gas is heavier than air, so it often accumulates on the floor of the house. Pets are much lower than people, so they are most likely to be victims of radon.

These phenomena often appear in newly renovated rooms, so they are also called "new house syndrome". People spend more than 80% of their life indoors, and indoor air quality is closely related to our health. If you and your family have these symptoms, please check and treat the indoor environment immediately and eliminate the "time bomb" buried around you as soon as possible.

misunderstand

Myth 1: many owners say: I use materials that meet the national regulations, and there will be no problem.

But standard materials are not equal to environmental protection materials; The reference material is not free of harmful substances, but only in a limited range; Use 10 board to reach the standard in a limited space, and it is not necessary to use 20 boards to reach the standard; And the more types of decoration materials, the more individual accumulation may exceed the standard. In addition, it is worth noting that the emission of harmful gases is closely related to temperature, and turning on air conditioning in Xia Dong or summer will greatly affect the emission of harmful gases.

Myth 2: Some owners think that the decoration must have an odor, and it will be fine if it is ventilated for a few months.

Let's not talk about the economic losses caused by the vacant property for several months. Ventilation is effective, but it can't solve the problem fundamentally. This is a typical method to treat the symptoms rather than the root cause. Because indoor air pollution is related to the incubation period of harmful gases, generally speaking, the incubation period of benzene is more than half a year, the incubation period of toluene and xylene is more than 1 year, and the incubation period of formaldehyde, which is the most harmful, can reach 3- 15 years (related to decoration technology and room temperature), so it cannot be said that the new house will be ventilated for a few months. In fact, you can do a comprehensive management for your new home as long as you use the rent and management fee generated by being vacant for one month. 24 hours after treatment, you can live a safe and healthy life.

Myth 3: Some owners also said: I decorated my new home like a park, and put a lot of green plants to absorb harmful gases. Should there be no pollution?

There is no denying that green plants can absorb some harmful gases, but the amount of harmful gases absorbed by plants is very small, which has little effect on eliminating pollution after decoration! In addition, don't forget two points: first, the photosynthesis of plants only inhales oxygen and exhales carbon dioxide at night like the human body, and most people go home to sleep at night; Second, a person inhales about 20KG of air a day, which is equivalent to the air weight of an ordinary room of 52 100 square meter. Green plants placed at home can absorb very little harmful gas in one day, but exhale a lot of carbon dioxide!

Myth 4: Some owners ask: I don't smell pungent, how can it exceed the standard?

When the formaldehyde exceeds the standard by less than 3 times, the pungent smell will not be smelled. When you smell the pungent smell, it has exceeded the standard by 4 to 8 times, which is enough to hurt you and your family. The smell of this gas is even more horrible, because you will be poisoned unconsciously, and when you find it, it will be too late ... especially in summer, when the temperature is high and the release of harmful substances such as formaldehyde is high, you should close the doors and windows and turn on the air conditioner. Indoor air can't convection with the outside world, and harmful substances will accumulate more and more, which is more harmful. And everyone has different feelings about harmful gases such as formaldehyde. There was once a lady surnamed Zhang who was particularly sensitive to formaldehyde because she was pregnant. Although the test result of the master bedroom was only 0. 10 ㎎/m2 (just up to the standard), she still suffered once in the bedroom, with dry throat, itchy throat and fatigue. So before the treatment, she would rather sleep in a well-ventilated hall than in a bedroom. We don't rule out her own psychological effect, but it is enough to prove that everyone reacts differently to harmful substances such as formaldehyde.

Myth # 5: Some owners also think that environmental protection materials should be used for decoration, and aromatic agents, grapefruit peel, tea and vinegar should be used after decoration.

In fact, using aromatic agent only masks the odor of harmful substances such as formaldehyde with a smell, and does not neutralize or decompose harmful substances. Using grapefruit peel, tea, vinegar and other means to adsorb, the adsorption effect is very poor, which can only make you and your family more poisoned!

Myth 6: Some owners also said, "How can it exceed the standard? A few days ago, the decoration company gave me a test that was qualified! "

In fact, the decoration company is only responsible for his decoration project, and will not be responsible for the furniture and other decorative items you buy. The reasons for exceeding the standard are mostly concentrated in customized wall cabinets, kitchen cabinets, ceilings and purchased TV cabinets, wardrobes, mattresses, sofas and so on.

According to the data of the World Health Organization, the number of people who die from indoor air pollution worldwide reaches 2.8 million every year! In China, the number of excess deaths caused by indoor air pollution is 1 1. 1000, the number of excess outpatient visits is 220,000, and the number of excess emergency visits is 4.3 million.

Expert tip: Decoration pollution is called the "invisible killer" indoors, and the harmful substances in it are more harmful to women, children and the elderly. No smell after decoration does not mean that there is no pollution, and formaldehyde exceeds the standard by more than 4 times to smell the irritating smell. For the health of you and your family, please carry out renovation pollution control before moving into the new house.
