In modern society, with the improvement of living standards, people's requirements for living environment are getting higher and higher. However, there is often a problem with newly renovated houses, and that is excessive formaldehyde. Formaldehyde is a common indoor air pollutant that is very harmful to human health. So, what standard does formaldehyde detection meet before you can move in?
First of all, we need to understand the ** of formaldehyde. Formaldehyde is mainly used in furniture, flooring, wallpaper, paint and other decoration materials. In the production process of these materials, formaldehyde is usually added in order to increase their hardness, wear resistance, corrosion resistance and other properties. In addition, in order to reduce costs, some unscrupulous businesses use low-quality materials containing a large amount of formaldehyde, which is also an important reason for excessive formaldehyde.
The harm of formaldehyde to the human body is mainly reflected in the following aspects: First, formaldehyde is a strong carcinogen, and long-term exposure to formaldehyde may lead to nasopharyngeal cancer, leukemia and other diseases. Secondly, formaldehyde can irritate people's eyes, nose, throat, lungs and other organs, causing eye pain, tearing, coughing, wheezing and other symptoms. Finally, formaldehyde may also lead to a decrease in the body's immunity and susceptibility to various diseases.
Therefore, for newly renovated houses, we must conduct formaldehyde testing to ensure that the formaldehyde content is within a safe range before moving in. So, what standard does formaldehyde detection meet before you can move in?
According to China's "Indoor Air Quality Standard" (GB T 18883-2002), the indoor formaldehyde concentration shall not exceed 01mg/m³。This criterion is based on the physiological response of the human body and the risk assessment of health. If the formaldehyde concentration exceeds this standard, the human body will have the above symptoms, and in severe cases, it will even be life-threatening.
In addition, the World Health Organization (WHO) has also put forward a recommended standard for indoor formaldehyde concentration, which believes that indoor formaldehyde concentration should not exceed 008mg/m³。This standard is based on a large number of scientific studies and practical experience, and is considered to be a basic requirement for safeguarding human health.
Therefore, when we conduct formaldehyde testing, we should use these two standards as the basis. If the formaldehyde concentration exceeds these two standards, we will not be able to move in. If the formaldehyde concentration is between these two standards, we also need to consider whether further treatment is needed on a case-by-case basis.
In general, there is no fixed answer to how many standards formaldehyde detection can be reached, and it needs to be judged according to specific standards and actual conditions. However, in any case, we should pay attention to the problem of formaldehyde to ensure that our living environment is healthy and safe.
