New house decoration pollution formaldehyde odor, what are the hazards?

Formaldehyde odor leads to abnormal body

After the home decoration , the pollutants appearing in the living room are mainly formaldehyde, ammonia, benzene, toluene, xylene, volatile organic compounds, and radioactive gas, etc. Physical contact with these harmful substances can cause headache, nausea and vomiting, convulsions, and difficulty breathing. etc., repeated exposure may cause allergic reactions, such as asthma, allergic rhinitis, dermatitis and the like, the long-term exposure can cause cancer (cancer, leukemia), or lead to abortion, and fetal malformations and growth retardation

Formaldehyde pollution and its harm

Formaldehyde ranks second in China's toxic chemicals control list and is identified by the World Health Organization as a carcinogenic and teratogenic substance. Formaldehyde is the main indoor pollutant, mainly from building materials, household items and so on. The concentration change of formaldehyde in the room is mainly related to the release amount and release law of the pollution source.

Bureau of Technical Supervision designated "standard content of formaldehyde in indoor air," it pointed out: the family room formaldehyde concentration maximum allowable value of 0.08mg / m3. The hazards of formaldehyde exceeding the standard are as follows:

1 When the formaldehyde content in the indoor air is 0.1mg/m3 , there is discomfort;

2 When the indoor air formaldehyde content is 0.2mg/m3 , it can cause pharyngitis, conjunctivitis and asthma;

3 When the indoor air formaldehyde content is 0.5mg/m3 , it can stimulate the eyes to cause tearing;

4 When the formaldehyde content in the indoor air is 0.6mg/m3 , it causes sore throat;

Higher concentrations can cause nausea, vomiting, cough, chest tightness, wheezing and even emphysema; when the concentration of formaldehyde in the indoor air reaches 30mg/m3 , it can immediately lead to death.

The World Health Organization pointed out that long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases, skin diseases, acne, female menstrual disorders, pregnancy syndrome, causing neonatal physical decline, and even cancer. High concentrations of formaldehyde are toxic to the nervous system, immune system, and hematopoietic system. According to the 2002 World Health Organization report: More than 70% of leukemia (blood cancer) patients are caused by indoor air pollution, and children are more vulnerable to air pollution than adults.

Indoor air pollution in new home decoration has become a "stealth killer" that endangers human health. One of the five major environmental factors, air pollution poses a hazard to its own health, which not only affects work and study, but also imposes a heavy economic burden on families. Moreover, it will cause leukemia, lung cancer, etc. due to pollution.

The newly renovated room or the new home purchased has irritating odors such as glare and pungent. The formaldehyde in the newly renovated house will exceed the standard. The first year after the home decoration, especially the first half of the year, is the strong release of harmful gases such as formaldehyde and benzene. volatile time period, formaldehyde up to 3-15 years

Decoration pollution in the four major misunderstandings

In the current home interior painting, the health problems of the home have increasingly attracted the attention of consumers. Many people have already learned about the dangers of indoor pollution, and also hope to improve the living environment, but often spend a lot of effort but fail to achieve the desired results. This is because we still have misunderstandings in our understanding.

Misunderstanding 1: Environmental protection building materials have no pollution

The so-called environmentally friendly building materials only emit less pollution and are not without pollution. The accumulation of less and more can also cause serious pollution.

Myth 2: After the renovation of the new house, stay in the air for several months.

Although the indoor air pollution can be enhanced by strengthening the air mobility in the room. However, since the release period of formaldehyde is as long as 3 to 8 years and the high evaporation period in 3 years, the removal of formaldehyde is a prolonged battle, at least 3 years. Therefore, it is necessary to use a window ventilation to remove harmful gases, and it takes a long time to take such a control method, and the effect is not large.

Misunderstanding 3: Green plants in addition to formaldehyde

Putting some green plants indoors is of little effect because:

( 1 ) Plants absorb formaldehyde through photosynthesis, and this function is absent when there is no light.

( 2 ) The absorption rate is low, and the maximum is only 20 micrograms per hour. It is effective to put hundreds of plants in one room. And when the concentration is high, the plants themselves will die!

Misunderstanding 4: Short-acting products in addition to formaldehyde

In the market, sprays, sprays, etc., which can eliminate formaldehyde, although these methods have a little effect, the cycle is short, the effect is poor, and secondary pollution is likely to occur.
