What is the national detection standard for formaldehyde?

Formaldehyde is a big "invisible killer" of indoor health. In 20 17, the world health organization listed formaldehyde as a carcinogen. Although formaldehyde is colorless and tasteless, it is irritating to people's eyes and nose. Under the external temperature and humidity conditions, it is easy to volatilize from the decoration materials and be inhaled by people. Long-term harm will lead to serious diseases such as cancer and leukemia. However, there will always be different levels of formaldehyde pollution in decoration, so how much indoor formaldehyde content is normal?

According to China's Indoor Air Quality Standard (GB/T 18883-2002), the limit of formaldehyde content in indoor air is 0. 10mg/m, which is suitable for residential and office buildings. Other indoor environments can refer to this standard.

The content standard of indoor formaldehyde pollutants is of greater significance to vulnerable groups. For the elderly, children, pregnant women, patients and other vulnerable groups, the harm caused by formaldehyde is far greater than that of the general population, so when there are vulnerable groups living, it is best to control the indoor formaldehyde content in a low range, so it is normal to keep the indoor formaldehyde content at least below 0.10 mg/m/m. In addition, the indoor volatilization period of formaldehyde is as long as 3- 15 years.

Formaldehyde is very harmful to the health of pregnant women.

Having said that, I think everyone should know how much indoor formaldehyde content is normal. Then, if the indoor formaldehyde exceeds the standard, what adverse reactions will the human body have in different concentrations of formaldehyde?

When the formaldehyde concentration in the air reaches 0.06mg/m-0.07mg/m, children will have mild asthma;

When the concentration of formaldehyde in indoor air reaches 0. 1mg/m, it will have peculiar smell and make people uncomfortable;

When the concentration of formaldehyde in indoor air reaches 0.5mg/m, it can irritate eyes and cause tears;

When the concentration of formaldehyde in indoor air reaches 0.6mg/m, it will cause throat discomfort or pain;

When the concentration of formaldehyde in indoor air is high, it can cause nausea and vomiting, cough, chest tightness, asthma and even pulmonary edema;

When the concentration of formaldehyde in indoor air reaches 30mg/m, it will kill people immediately.

Symptoms of formaldehyde's harm to human body

Indoor formaldehyde content and different concentrations have different degrees of harm to human body. The higher the formaldehyde concentration in indoor air, the more serious the harm. After the renovation of the new house, formaldehyde pollution must not be ignored. You'd better have a professional formaldehyde test before moving in. When the indoor formaldehyde content is controlled below 0. 10mg/m, it is normal.

Once you find signs of formaldehyde poisoning, you'd better contact professionals outside in addition to formaldehyde Company for indoor formaldehyde control in time to create a green and healthy breathing environment for yourself and your family.
