Is my house formaldehyde exceeds bid? Is other and toxic harmful gas had in indoor air? Last a period of time 49 days, south " room of ancient bronze mirror is round " first-run and indoor pollution detects the result gives heat! This " room of ancient bronze mirror is round " by south combine authority to detect orgnaization composition, 10 are singled out to offer whole house to detect freely in many 200 object signing up. Detect according to " standard of indoor air quality " (GB/T18883-2002) is carried out, nod to sampling amount, position, height, time operate strictly according to professional level.
The result shows, 10 detect in example, formaldehyde exceeds mark phenomenon more, benzene is content (benzene, toluene, xylene) amount to mark entirely, only a sampling burns total volatile organic matter (TVOC) exceeds bid. The expert expresses, the furniture volume that formaldehyde content exceeds 4 example with more mark bears the weight of rate in 10.8% above, most be as high as 27.6% , it is to build what exceed bid into the formaldehyde inside the space advocate so one.

Via be being chosen strictly, final 10 case show itself, enclothe Li bay, more beautiful, sea bead, the Milky way, Bai Yun, time the central area such as Yu, and suffer Guangzhou citizen two this years to chase after the wide Buddha boundary that hold in both hands fully.
Appraisal setting
In detailed list of skill room consign
Still detect without air project
Guangdong province pledges senior engineer Chen Jiwen introduces check courtyard, " standard of indoor air quality " (GB/T18883-2002) , accord with a person to reside healthy measure, but it is guiding standard only, to building business, decorate business, furnisher to do not have sanction. It is with skill room exemple, in building of Guangzhou great majority dish can press requirement sampling observation, but very few meeting an one check. In the detailed list when skill room consign, detect without indoor air this one. Secondhand the room is custom-built decorate more restrain without relevant contract.

Sampling nods the photograph of breathing zone height of high in principle and person to agree, opposite height 0.5 ～ 1.5 meters between.
Appraisal result
Formaldehyde exceeds bid generally the 1 times most excellent much
" standard of indoor air quality " (GB/T18883-2002) regulation, standard of indoor formaldehyde content is restricted to be worth for 0.10mg/m3, it is the lowermost concentration that nasal cavity, voice can find formaldehyde is exciting. In 10 example, secondhand the circumstance exceeding bid that room entire room decorates relatively concentration. More beautiful area farming tell an around blame village alone building 116 square metre are southwest to secondhand children room formaldehyde of the residence exceeds mark 1.5 times, master room formaldehyde exceeds bid 1 times, range exceeding bid is top. Owner changed before the bed of child room and wooden floor, this is probable the main source that is formaldehyde. In addition, nuo heart name southeast 135 square metre to secondhand of the residence advocate lie formaldehyde exceeds bid 1 times much, the buy inside the room has ark of end of bed, dresser, bed, cloakroom, furniture bulk bears the weight of rate amount to 14.3% , especially cloakroom uses board most concentration. Garden of fine horse scene 109 square metre north to secondhand kitchen formaldehyde of the residence exceeds bid 1 times, purchase have brand-new ambry.
Skill room respect, cruel of rice of 10 thousand divisions 25 square metre north exceed bid to the bedroom formaldehyde of skill LOFT unit 1 times much. Before detecting, owner acquired bed, chest, dresser secondhand furniture, furniture bulk bears the weight of rate amount to 11.3% . The expert expresses, formaldehyde is released is a long-term course, what owner adds is secondhand furniture produces an effect probably to the result. Dong Shanyin resembles a 54 square metre north to garden of skill residence, Oriental bright phearl southeast 220 square metre to secondhand the residence has dot of a sampling to exceed bid each.
10 case all amount to content of benzene department other people mark

Below drafty circumstance, benzene department other people is in 3-6 can fall after the month safe value is the following. In 10 case that detect this, benzene fastens the content of content to all amount to mark.
TVOC content detects only 1 case does not amount to mark
There is peculiar smell after a lot of houses are decorated, detect formaldehyde did not exceed bid however, may TVOC brings about this. TVOC is a few floorboard that have volatile organic thing, exist in order to enrage bodily form type below normal temperature.
TVOC is affected to human body health basically is exciting eye and respiratory tract, make the skin allergic, make person generation has a headache, pharynx is painful with lack of power, still contained a lot of carcinogenic substance among them. Basically come from paint, coating and adhesive.
" standard of indoor air quality " (GB/T18883-2002) regulation, standard of indoor TVOC content is restricted to be worth for 0.60mg/m3. Detect the result shows, only spic garden village 101 square metre north to secondhand the circumstance that the residence exists not to amount to mark, content of guest room TVOC is 0.71mg/m3.
Reporter spot sees, guest room accumulation has paper box and sundry, appliance of pottery and porcelain waits of the cup inside, and flavour of the cabinet in the room is heavier.
Owner introduction, what the cabinet uses is real wood grain board, by decorate company field assembly, glue was used when installation, the bottom completed installation at the beginning of Feburary this year in January. Detect personnel expresses, do not eliminate relevant and sundry meeting influence detects result.
Example is analysed
A
Building of unripe darling of plan equipment pregnant detects formaldehyde exceeds bid 1 times much
Place: More beautiful area farming tell an around blame village alone building 116 square metre are southwest to secondhand the residence
Door model: Build 115 square metre 3 rooms one hall, southwest front, ventilated, daylighting is better.
Equipment: Sampling appearance 3
Example circumstance: This since enters " marriage room " , also be the long-term house place that is about to greet little baby.

Painting and the level raised on the choice of furniture, avoid the generation of formaldehyde as far as possible. What choose like sofa is cloth art material, the bed chooses German derma material, the cabinet chooses custom-built household. What owner worries quite is the wooden floor of infantile room, according to introducing, new floor board is one knows the friend that decorate to help of the shop, brand name and manufacturer home name did not mark on plank. Stem from the accredit to the friend, owner also did not examine minutely too much, where does the material that also does not tell a floor board up to now come from.
The spot detects: That day afternoon at 3 o'clock, detect personnel begins to put into house detect equipment, be in respectively room of sitting room, child, advocate lie 3 place are put.

Appraisal person say
Formaldehyde is released the longest can amount to 10 one's remaining years
Benzene fastens thing half an year to be able to fall to safe value
To this second " room of ancient bronze mirror is round " first-run detect result, liang Yubin of engineer of project of academy of Guangdong product quality supervision and inspection introduces, its and detect the relation between the particular case of example is reasonable in reasonable range. In recent years, people cares more and more to decorating pollution. These year rise because of consciousness, choose good stuff, extent exceeding bid also was reduced greatly. And this second 10 detect in example, formaldehyde exceeds bid much, and all of benzene department other people amounts to mark, how to understand this differentia different? Liang Gong expresses, the physics of two kinds of pollutant, chemistry is different, its release the rule to also can differ. Consider to make clear, of the formaldehyde in furniture releasing is a slow process, the longest can amount to 10 old long. And summer weather is burning hot and damp, can accelerate the rate that formaldehyde releases. And benzene department other people falls in drafty circumstance, 3-6 can fall after the month safe value is the following. This second " room of ancient bronze mirror is round " appear the sample that exceeds bid, it is to be decorated for the most part time and detect time-interval is in 1 ～ between 6 months.
Large area uses board
Meeting overlay accumulates formaldehyde
Epicycle detects centered July, whether can be the weather of burning hot moisture affected detect result? Liang Gong expresses, the weather of burning hot moisture can accelerate the rate that formaldehyde releases really. In fact, besides temperature and humidity, quality of furniture amount, product actors or actress low-grade metropolis influence detects index result.
Sampling dot formaldehyde exceeds bid taller, furniture bulk bears the weight of rate often also on the high side. Liang Gong thinks, single board does not exceed bid, but if whole house bedding face accumulates use plank, formaldehyde can produce overlay to accumulate effect, the formaldehyde content that makes indoor air finally medium exceeds bid. Cite a case: Advocate lying independent cloakroom, the space is little ventilated difference, plank is used much, often formaldehyde exceeds bid serious.
Appraisal is compensatory
Prevent formaldehyde to exceed bid optimal choice:
Select product of standard of high environmental protection
Strengthen ventilated take a breath at the same time
Can divide roughly except formaldehyde product on market at present kind: One kind is chemical reaction law, effectiveness is how old, can last how long become effective and whether to have pollution 2 times, still prop up without relevant experimental data at present. Another kind is physisorption law, theoretic effective, but its adsorption range is narrow. Formaldehyde by adsorption hind, be it is difficult also to was decomposed or can be released once more affirmatory.
The home that chooses level of high environmental protection resides a product, strengthen ventilated take a breath, provide the auxiliary sex measure such as system of air purifier, new wind, it is the optimal choice that avoids indoor formaldehyde to exceed bid. Before be being entered, undertake detecting, ensure safety does not have anxiety, enter just now. In addition, the house home that has a child is decorated had better not use marble these stone capable person that have radioactivity material presence, do not use need a large number of adhesive or glue come of agglutinate answer plywood furniture. Whitewash the wall color of not smooth graph is gorgeous and the choice graces paint, children room still uses light color, tall danger material also is met a few less.
