Formaldehyde is endangered by the public in recent years. It will not only pollute the environment but, more importantly, it will have a great impact on the human body. However, not all people know about formaldehyde and may only know that there is formaldehyde in the home improvement. In fact, formaldehyde is found in many places in life. Today, Xiao Bian took everyone to understand what is the national standard for formaldehyde ? What formaldehyde hazards in life?
First, how much is the national standard for formaldehyde?
Modern people are almost talking about the color change of formaldehyde, because formaldehyde exists in all aspects of life, and we live in this colorless gas with a special stimulating odor all the time. It has an irritating effect on our eyes, nose, and respiratory tract. Once the formaldehyde content in the air exceeds a certain standard, it will cause irreversible damage to the human body, and even have the risk of cancer.
There will be formaldehyde, benzene and other hazards in the home improvement. This is the reason why the newly-decorated house cannot be accommodated immediately. At this time, I believe that everyone wants to know what the national standard of formaldehyde is, as long as the formaldehyde is controlled within the standard range. The impact on the human body is basically negligible.
What is the national standard for formaldehyde? At present, China's standards for formaldehyde are mainly divided into two categories: civil buildings and second-class civil buildings. Class I includes residences, kindergartens, hospitals, school classrooms, and vehicles. The formaldehyde standard at these sites should be controlled at ≤ 0.08 mg/ Within the m3 range, the standard control of benzene is in the range of ≤ 0.09 mg/m3, the ammonia control is in the range of ≤ 0.20 mg/m3, and the overall volatile organics are controlled in the range of ≤ 0.50 mg/m3.
Class II standard buildings include office buildings, hotels, bookstores, shops, gymnasiums, libraries, barbershops, etc. Their formaldehyde standards should be controlled within the range of ≤ 0.10 mg/m3, and the benzene standard should be controlled at ≤ 0.09 mg/ Within the range of m3, ammonia control is in the range of ≤ 0.20 mg/m3, and total volatile organics TVOC should be controlled in the range of ≤ 0.60 mg/m3.
If the formaldehyde standards detected in these types of civil buildings, such as the corresponding types, exceed the above values, it indicates that the toxic gas in the room has exceeded the standards and will cause varying degrees of harm to the occupants' health. When the concentration of formaldehyde reaches 0.06-0.07mg/m3, young children will have slight asthma;
When formaldehyde reaches 0.1mg/m3, there will be irritating odor and discomfort; when formaldehyde concentration reaches 0.5mg/m3, eye irritation will cause tearing; if formaldehyde content reaches 0.6mg/m3, it will cause throat discomfort and pain Once the formaldehyde concentration exceeds a higher level, it will not only cause nausea, chest tightness, wheezing, cough, vomiting, pulmonary edema, etc., but will even cause death immediately.
Second, what are the hazards of formaldehyde in life?
1, room decoration pollution of formaldehyde
Formaldehyde pollution in the decoration is well-known, as some home decoration materials, furniture, artificial plates, all kinds of paints contain formaldehyde.
2, textile formaldehyde pollution
Formaldehyde pollution is present in many fabrics and textiles because they use formaldehyde-containing compounds to increase the fabric's elasticity, crease resistance, and color fastness.
3, food formaldehyde pollution
Formaldehyde is used as a food additive by many unscrupulous molecules. It can coagulate proteins, increase the taste, improve the appearance and so on.
Editor's summary: The above is about the formaldehyde is how many national standards and formaldehyde hazards in life, I hope the contents of Xiaobian can help everyone, to better understand the formaldehyde, to avoid the harm of formaldehyde.
