Director Song Guangsheng, director of the National Indoor Quality Supervision Center, believes that people use air conditioners throughout the summer to close the doors and windows of the rooms, resulting in low indoor air exchange rates. Secondly, in the summer when temperatures are high and humidity is high, because of buildings, The interior decoration, furniture, and indoor furniture such as formaldehyde, ammonia, benzene, and other toxic and harmful gases are increasing. The third is that when cooking at home, the range hood can not exhaust fume gas into the room.
In addition, studies have shown that when the temperature is high, the blood vessels of the human body are enlarged, the viscosity of the blood is increased, and the ferrets, patients, pregnant women, children, and people with poor health have poor physical ability and heat resistance. The intrusion of various types of chemical pollutants in the indoor air is more likely to cause danger to the human body and aggravate the symptoms of cardiovascular patients.
The human body feels self-infected to deal with indoor pollution in summer. Apart from the establishment of window ventilation, some of the frequently used air-purifying substances and equipment can effectively reduce indoor harmful gases. At the same time, we must also pay attention to the fact that improper preparation of pollution cannot not only eliminate pollutants, but also cause secondary pollution.
Some experts told reporters that China's indoor air pollution comes from the top four major evils: formaldehyde, benzene, total volatile organics (TVOC) and ammonia. How quickly can indoor air be polluted? In the future, Beijing Institute of Technology Development Co., Ltd., director of indoor environmental protection division Qu Lingbo introduced that consumers can first close the room for 12 hours, if after entering the feeling of the eyes become astringent, spicy, throat dry, there must be excessive formaldehyde If you stay indoors for 10 minutes, smell a faint smell, and feel sleepy, there must be more than 3 times the benzene exceeding standard; and if there is no abnormal feeling in the eyes, do not get sleepy or burnout, just feel the chest tightness, then Total Indoor Volatile Organic Compounds (TVOC) exceeded the standard.
â– Pollution preparation
1. Ventilation is done every day. Rooms that use air-conditioning in summer, rooms that are polluted by ammonia gas, and rooms that are newly renovated and new furniture are installed, should pay attention to the ventilation of windows every day.
(2) Newly-installed rooms after the summer check-in If the premise permits, the newly renovated family is best to escape the harmful gas release period in the summer and then stay, there are more people in the family day, children and pregnant women should pay attention.
3. In the summer, many people do not stay in the room for a long time in summer, especially when they are white, children and people with weak constitutions. They can be manipulated to perform outdoor activities sooner or later.
4. Timely management Once indoor air odors and family physical abnormalities are discovered, timely contact with the indoor situation monitoring agency and targeted purification and treatment.
■Do not believe that there is a misconception in the area of ​​pollution. There is a consumer test, fumigation vinegar to remove the odor after renovation. Experts pointed out that vinegar is an acidic substance that has a faint influence on the ammonia in the weak neutral air, but it does not react with formaldehyde and other harmful components. The use of tea slag, grapefruit skin, onion slices, pineapple blocks and other soil preparation can only play a role in whitewash odor, these things will not receive formaldehyde in the air.
Nasal spray and refreshing agent can easily cause secondary pollution. Purging the indoor air with nasal spray and air freshener is not a good choice because the chemicals in the nasal spray and air freshener may react with the substances in the air and cause secondary pollution.
Do not over-rely on plants. Some indecent plants can receive certain toxic gases. For example, plants that can receive formaldehyde include fairy palm, spider plant, aloe vera, ivy, cycad, chrysanthemum, etc.; ivy, cycad, chrysanthemum, etc. Can reduce benzene pollution. However, in the period of end of the renovation of harmful gas dense plant, the weak reception of plants, not only can not cut off the root pollution, and even their own health can not be guaranteed.
New fabrics were used for curtains, tablecloths, sofa sets, curtains, and carpets. Many people bought them directly and used them directly. In fact, decorative fabrics often intervene in the production process, additives and dyes, including formaldehyde. Dark fabrics and specially treated fabrics such as anti-wrinkle, soft, etc. have a greater formaldehyde content. Therefore, it is advisable to fully immerse the cleansing water in the cleansing water after buying it, so as to reduce the residual formaldehyde content. When purchasing, there is no odor and the color is lighter and safer.
Newly-packed room smells after summer
In summer, air pollution in the room is more serious because of lower air pressure and slower indoor air movement.
