How serious is formaldehyde exceeding the standard?

Exceeding the national standard of 0. 10 mg/m3 is considered serious.

The Indoor Air Quality Standard (GB/T 1 8883-2002), which was implemented on March12003, was formulated to protect human health and prevent indoor air pollution. The regulation of formaldehyde is that the average value of 1h should be less than or equal to 0. 10 mg/m? .

Formaldehyde volatilizes for a long time, and the release time of formaldehyde contained in decoration materials such as wood-based panels is about 3 ~ 15 years. It is unrealistic to expect formaldehyde to evaporate after a few months of ventilation. Moreover, formaldehyde exists in a wide range, and almost more than 90% of building materials such as composite floors and density boards on the market contain formaldehyde.

Precautions:

1. Keep ventilation. Ventilation is the best way to remove formaldehyde. After the renovation of the new house, we must pay attention to ventilation. The newly renovated house had better be left to dry for several months before moving in.

2. Buy products with guaranteed quality: formaldehyde residues often exist at home. If conditions permit, buying furniture of big brands can also be relatively guaranteed. In addition, try to use environmentally friendly home improvement materials when decorating.

3. in addition to formaldehyde with activated carbon and plants: Activated carbon adsorption and plants also play a certain in addition to formaldehyde role. The structural characteristics of activated carbon are many pores and strong adsorption. It is best to choose activated carbon with relatively small particles. The smaller the particles, the better the adsorption effect. Generally, newly renovated rooms use activated carbon, and the dosage is per square meter 1 bag (50g). Chlorophytum in plants has a strong adsorption effect on formaldehyde, so more can be put in the new room.

People's Network-The higher the temperature, the easier it is for formaldehyde to exceed the standard.
