Four reasons for indoor pollution:
First, air conditioners are commonly used in summer to reduce the temperature. The door and window of the room are closed tightly, and the indoor air exchange rate is relatively low.
Second, some toxic and harmful gases increase in the case of high summer temperatures and high humidity. Japanese indoor environmental experts have shown that when the indoor temperature is 30 degrees Celsius, indoor toxic and harmful gases are released the most.
The third is the impact of summer weather changes. In summer, the humidity in the air is relatively large, and the air pressure is relatively low, so that the convection of the indoor air and the outdoor air is correspondingly reduced, which easily causes the retention of the polluted gas.
Fourth, the metabolism of the human body in the summer and the volatile components of various domestic wastes increase, which further increases indoor air pollution.
Experts said that in the past two years, the indoor environment test of homes and office buildings in the Beijing area found that indoor air pollution in summer exceeded the other seasons by more than 20%.
Testing and governance are urgent
The harm of indoor pollution to the human body is well known. In summer, the weather is hot. The elderly and children, as well as the sick and the weak, increase the indoor stay time and reduce the outdoor activity time. Therefore, these people are the most serious victims.
Have the following performance to be vigilant
1. When I wake up every morning, I feel depressed, sick, and even dizzy;
2. The family often has a cold;
3. Although not smoking, and rarely touch the smoking environment, but often feel uncomfortable, foreign body sensation, poor breathing;
4. Family members often have skin allergies and other problems, and are mass-generating;

11. Newly renovated rooms or newly bought homes have irritating odors such as glare and pungent, and they still smell for more than a year.
The first is to determine the decoration plan reasonably. In particular, it is better not to use the same material on a large area of ​​the floor material of the room, and to reasonably calculate the usage of the large core board in the room;
The second is to scientifically select the construction process. In addition to special requirements, generally do not lay a large core board under the laminate floor. Cabinets and heating hoods with large core plates must be sealed with formaldehyde sealant. It is best not to have exposed areas. It is best to use thicker oil film and good sealing.
The third is to strictly control the quality of materials for decoration and decoration. When purchasing laminate flooring and large core sheets, the amount of formaldehyde released should be taken as the main condition for selection;
The fourth is to extend the check-in time appropriately. If conditions permit, you should try to let the indoor ventilation for a period of time to stay, so that the indoor formaldehyde is released as much as possible;
The fifth is to pay attention to the detection and purification of indoor formaldehyde. Especially in families with elderly, children and allergic members, the indoor formaldehyde content must be strictly controlled.
