Monitor finding the air quality of children's room is poorest
The face autumn rain reporter of the reporter Wang Yan learns from Center for Disease Prevention and Control of Shashi of Governor of Hunan recently, in 2009 of 2006, this centre monitored the result to analyze and discover to the air quality of the room of citizens of 1027 Changsha, in the harmful substance of detection, have the most common formaldehyde. The harmful substance exceeds standard the house is seen at most with children's room in the air, the exceeding standard rate is up to 41.8%. The others successively mainly poach the exceeding standard rate and reach 33.5%, the study exceeding standard rate reaches 23.4%, the kitchen, bathroom, exceeding standard rate of restaurant reach 20.0%, the sitting room exceeding standard rate is the lowest, it is 12.6%.
This centre occupational health monitor department section chief, room environmental the intersection of expert and money if Professor speak just, there are relatively more children's room, renovation material that mainly lies and uses, such as the wardrobe, dressing table, timber apron, children's room also has toy shelves. Two air conditioner frequency of utilization high turning on windowing, ventilating little room these, apt to cause harmful substance exceed standard in the indoor air. Room person who exceed standard of environment 37.2% in the 1 month fit up, exceeding standard rate for 1 will it be 3 months month 35.7%, the exceeding standard rate of environment of the room of 3 months and 6 months has already dropped to 22.7%, more than are dropped to 17.8% in 6 months. So, citizens had better take a breath after equipment through the ventilation of half a year, then move in.
Jin RuoGang reminds and says, the ubiquitous misunderstanding is to think that so long as all adopt the material in environment protecting mode at present, can guarantee the requisite quality of final indoor air. In fact, it is two totally different concepts that the air environmental protection up to standard of material is up to standard. First, the material is not up to standard of, but indoor air quality may be up to standard of. If though has used E2 Wood-based plate non- in environment protecting mode of grade (E2 Grade is qualified grade) ,It is very small to use the density, its pollution rate is just very small, the indoor air might not exceed standard. Second, the material is up to standard, but may cause the pollutant total amount in the indoor air to exceed standard. As interior decoration uses though the wood-based plate reaches E1 Grade (environmental protection grade) The standard, but will cause indoor formaldehyde to exceed standard etc. if it is too high to use the density. In addition, the room area,etc. has certain influence on air quality.
