Recently, the Indoor Environmental Testing and Control Center of Zhengzhou Environmental Protection Industry Association conducted an “indoor free testing and registration activityâ€. Through on-site air sampling and laboratory analysis, the data showed that the content of formaldehyde and benzene in 10 well-decorated children's rooms was common. Exceeding the standard, and the source of pollution is furniture and wall and decoration materials.
10 children's rooms are all "pollution"
In late June, the staff of the Indoor Environmental Testing and Control Center of Zhengzhou Environmental Protection Industry Association went to the residents' homes to test the air quality in their indoors, especially in children's rooms. The result was shocking: formaldehyde and formaldehyde in 10 well-decorated children's rooms. The content of benzene exceeded the standard.
Location: The walls of a resident's house are affixed with wallpaper, and the floor is covered with a composite floor. The piano frame made of MDF exudes a pungent smell.
Test results: The normal content of formaldehyde per cubic meter is 0.10 mg, and the detection value is 0.412 mg, which is 3.1 times higher than the standard. The normal content of benzene per cubic meter is 0.11 mg, and the detected value is 0.223 mg, which is 1 times higher than the standard.
On-site comment: In order to make the composite floor have the effect of solid wood floor insulation, some decoration companies often put a layer of low-cost large core board under the composite floor, in which the free formaldehyde emission is very high.
Among the various decorative materials, the environmental performance of the wallpaper itself is very high. Now many companies use imported base paper or natural plant fiber as the base paper, which is basically free of pollution.
However, the glue that attaches the wallpaper to the wall is polluted by air. For example, the coating material of the wallpaper contains the high-molecular polymer pvc, which will decompose at a high temperature to generate chlorine gas harmful to the human body.
MDF currently refers to MDF in the general sense. It is usually made of wood fiber or other plant fiber, and is made of urea-formaldehyde resin or other suitable adhesive. It contains a lot of formaldehyde. The child's room is best made of solid wood furniture. .
Location: In the house of a city garden, all the stickers from top to bottom are wallpapers, the roof is a plasterboard ceiling, and inside is a blockboard. The material used in children's beds is MDF.
Test results: The detected value of formaldehyde is 0.441 mg, which is 3.4 times higher than the standard. The detected value of benzene was 0.211 mg, which was 0.9 times higher than the standard.
On-site comment: The main material of the ceiling is gypsum board. The blockboard is the same as the MDF. It is also made of wood and glue. It also contains a lot of formaldehyde.
The binder of the board contains a large amount of benzene. When the human body inhales excessive amounts of benzene series substances, it is dizzy, nausea, fatigue, dry skin, and blurred consciousness. In severe cases, it can cause coma, even liver and kidney failure, causing blood diseases.
Cloth toys and sofas contain a lot of formaldehyde. You should choose the products produced by Dachang. Do not buy small workshops with obvious pungent smell.
The more refined the decoration, the more serious the pollution
"The 10 children's rooms we tested this time, the indoor air pollution is relatively light, and they are all simple renovated houses. The pollution is more serious, all are well-decorated houses." Director of the Indoor Environmental Testing and Control Center of Zhengzhou Environmental Protection Industry Association Said that pollution mainly comes from new furniture pollution, wallpaper pollution and indoor fine decoration pollution.
Experts said that from 2006 to the present, he was exposed to 26 people in the work caused by leukemia caused by renovation, 4 were adults, and the remaining 22 were 2 to 8 years old.
At present, four major causes of leukemia are chemical contamination factors, infection factors, radiation factors and genetic mutations.
Ammonia is the "number one killer" for indoor pollution. It comes from brick, tile, steel, cement, stone, plaster, ceramics and other materials. It has a clear carcinogenic effect and directly kills the body cells of the killer if the killing cells occur. Mutations have the potential to cause cancer.
Experts suggest that you should use solid wood materials or furniture made of electronic plug-in boards, and pay attention to the furniture volume should not exceed 50% of the room to facilitate ventilation.
Solvent paints and coatings are rarely used in the house. Try not to affix the wallpaper on the wall, but paint the paint. Do not lay laminate flooring, use solid wood or bamboo flooring. If the floor tiles are hard, you can lay a layer of wool carpet on it, but pay attention to timely replacement.
The curtains in children's rooms are best made of pure cotton products to increase the breathability.
For the decoration of children's rooms, the less construction process and processing procedures, the better the lighting and ventilation should be taken into account.
Light pollution enhances ventilation
Parents are already conscious of testing before the house is in place, but to prevent contamination of the children's house, we must start from the source. Check the decoration materials, that is, check the decoration materials and decorate them with materials without pollution.
The inspection is in the process of stopping the heating and not using the cooling facilities. The temperature is the lowest in the whole year, the time for closing the doors and windows is the shortest, and the pollution concentration is the lowest. Because the temperature increases by 1 degree Celsius, the pollution is increased by 0.15 times. For every 1 hour of closing the door and window, the pollution is increased by 0.08 times, and the 10 free households are new houses that have been renovated for less than one year. Therefore, the houses with excessive pollution exceeding 9 times are not detected, and the average pollution concentration is also higher than that. The city's average test value for the winter and summer seasons fell by 24.2%.
The testing center reminds the public that if the room exceeds the standard within 2 times, there are no children, pregnant women, and the elderly. Basically, you can stay and do not need to be treated, but the indoors must maintain 3 to 5 hours of continuous ventilation time every day. Naturally after one year. Can be close to the standard.
If the medium exceeds the standard, it is not suitable for staying due to differences in personal physical strength and resistance. It is recommended to take necessary preventive measures.
Do not stay in a house that exceeds the standard by more than 5 times.
