How normal is the standard range of formaldehyde?

Modern people have a high sense of safety. As we all know, if the formaldehyde in the house exceeds the standard, it will do great harm to our health. If you stay in an environment with excessive formaldehyde for a long time, it will easily lead to dizziness, cough and chest tightness. It may even be life-threatening, but as long as it is controlled within the standard range, it will not have an impact. Come and find out right away.

1. How normal is the standard range of formaldehyde?

The main source of indoor formaldehyde is the volatilization of decorative materials and furniture. China's standard is that the indoor formaldehyde value should not be greater than 0.08 mg/m, even if it exceeds this standard, it will have different degrees of influence according to the excessive concentration. The common symptoms are dizziness, chest tightness and poor breathing, which must be paid attention to.

Second, the harm of formaldehyde to human body:

1, slight formaldehyde pollution

The formaldehyde content of 0.09mg/m-0.3mg/m belongs to mild pollution, which is often easily overlooked, because the human body will not have much reaction at first in this environment, but it will have symptoms such as dizziness, cough and chest tightness after living for a long time.

2. Serious formaldehyde pollution

0.4mg/m-0.8mg/m belongs to severe formaldehyde pollution. Compared with mild formaldehyde pollution, the symptoms are more intense. Within 48 hours of severe formaldehyde pollution, there will be symptoms such as dyspnea, sore throat and general fatigue, and indoor plants will wither for no reason. If your home is seriously polluted by formaldehyde, you must move out at once, otherwise it will threaten your life.

Third, how to remove formaldehyde

1, ventilation mode

After the renovation of the new house, we should first open the doors and windows to ventilate and let the toxic gas out of the house. If possible, it is advisable to air it for 3-5 months. Because the density of formaldehyde is higher than that of air, it is easy to precipitate, and the window spacing is generally higher than 1m, which is not conducive to the complete emission of formaldehyde. It is obviously unscientific to judge whether you can stay only by smell. Formaldehyde is odorless and cannot be identified by feeling.

Use green plants

You can put some green plants at home, such as chlorophytum and agave. Which has a particularly strong absorption capacity. The absorption of green plants can be used as an aid, but don't attach too much importance to its role.

Conclusion: I will introduce the standard range of formaldehyde to you here, hoping to help you.
