Recently, the thing that hire soares has not gone, rental apartment formaldehyde exceeds mark to be troubled by bubbling with noisely again, the friend is encircled today is more by " employee of the P7 in A gets leukaemia die, rented freely formaldehyde house before one's death " the article brushs screen.
Say in the article, king of the employee in A leased the building of freely some this year, because acute marrow fastens leukaemia misfortune,died in July. His wife makes after detecting, discover indoor formaldehyde exceeds bid to the building, think this is the main factor that causes Wang Mou to die, sued freely then.
Wide attention of the netizen was caused after the article is given out, outside the freely company that provides the service that rent a house besides condemn, a lot of people also appeared doubt and panic:
Indoor formaldehyde unexpectedly so horrible?
Can the house formaldehyde that I stay in exceed bid? Can you still live?
How should I do?
Formaldehyde, common indoor contaminant
Formaldehyde exceeds bid, be in China actually very general.
A research 2017 shows, the formaldehyde chroma with Chinese town indoor new home is in 0.18mg/m3, the national level that exceeded Ministry of Public Health to announce (0.10mg/m3) .
Transcend the problem of mark about building formaldehyde, be exploded to had gone out a few years ago, but did not cause too much attention in those days.
Have a meal, sleep, employ computer... , at least 1/3 can be waited for in house, indoor environment has not little effect to health.
All sorts of data that when decorating, use, for example fabric of coating of man-made plank, paint, chemical fibber, they are the main source of indoor formaldehyde.
Formaldehyde can stimulate mucous membrane of the eye of people, respiratory tract, bring about weep, the symptom such as difficulty of voice ache, sneeze, cough, breath, still can cause asthma.
Animal experiment and epidemiology consider to make clear, formaldehyde can bring about the happening of cancer of human nose pharynx. 2004, authoritative international cancer research organization (IARC) it is formaldehyde classify 1 kind of carcinogenic substance.
Decorate formaldehyde to exceed bid, can you get leukaemia?
Before this freely incident, we see similar story via regular meeting:
A few months after the house that such-and-such occupy new clothes builds, fish leukaemia, lymphatic tumour, or a certain other cancer. The course detects, discovery is the formaldehyde in the home exceeds bid.
Formaldehyde is indoor decorate the commonnest, exceed the contaminant of mark the most easily, it also is 1 kind of carcinogenic substance really, can increase the risk of cancer of human nose pharynx.
Formaldehyde is put in the likelihood that causes leukaemia really, but this basically is the adult leukaemia that is based on a profession to expose, namely so called occupational disease, for instance and so on of factory of oil industry, shoemaking.
That is to say, because a few people work in chemical plant and other places, follow formaldehyde of taller pH indicator for long to be contacted closely, the odds that suffers from leukaemia can rise.
And we live daily medium formaldehyde remains, the dose that exposes than these professions is small much, need not too panicky.
The formaldehyde that current research cannot prove to install build and repair to become exceeds there is immediate concern between mark and leukaemia, but decorate brought pollution actual however existence, endangering our health.
Decorate pollution, have formaldehyde not merely
Decorate the indoor contaminant that cause, still have a lot of kinds besides formaldehyde, can divide pollute 3 kinds big for organic contaminant, inorganic contaminant, radioactivity.
At present home already the contaminant that check gives basically has:
Benzene, toluene, xylene, styrene, ammonia, radon...
Their origin is:
Man-made plank, paint: May release the harmful material such as a benzene, toluene, xylene, formaldehyde, can wait for generation stimulation to the skin, eye and the upper respiratory tract;
Silt, tile and cement concrete: The likelihood contains urea, in temperature the meeting below higher case releases ammonia, stimulate the skin and mucous membrane, let a person feel eye, nose is uncomfortable;
Material of a few natural stone: Can release have emissive radon, cause radon pollution;
...
It is the home no matter in, bazaar, hotel, company... the place that if pass,decorates only, possibly pollution exists. Paint of window of floor, ambry, door, sofa, wall, may be the origin of contaminant.
Face pollution, how can we do?
Be in China, indoor decorate contaminative problem to exist generally. Wait for pollution for eliminate formaldehyde, everybody thought various way...
Somebody hears activated carbon has sorption, filled up with in house activated carbon;
Return somebody to hear green plant can purify air, wish to be planted in house Man Luluo and bracketplant...
Actually... these two kinds of methods, to reducing the total volatile organic compound in contaminant (TVOC) have a few effects, but not big to purify formaldehyde good.
A lot of indoor contaminant, have volatile, settle their truly efficient way, besides use qualification outside decorating material, have only:
Ventilated (air of commutative room inside and outside)
Current and common ventilated have two kinds of kind:
System of 1. new wind
Purify the air outdoor through new fan, reintroduce is indoor, achieve the goal that air of room inside and outside exchanges. The effect of the contaminant such as formaldehyde of purify of this kind of method is stabler, but the price is higher.
2. opens a window ventilated
Open a window ventilated the biggest advantage is: Do not spend money. But its effect is not stabilized quite, if wind is too small, air is incorrect flow, cannot let indoor contaminant come loose go out. But the time with right wind, its result is very right.
Research makes clear, short time opens a window ventilated 10 minutes, the chroma of the formaldehyde in indoor air can reduce 70% ～ about 90% . When weather is good, might as well many open a window.
No matter choose which kinds of ventilated method, need to notice:
The ill other people such as formaldehyde, benzene volatilizes very easily, summer temperature is high, plank releases the ill other people such as formaldehyde the meeting is more serious, because this summer should notice ventilated purify formaldehyde more.
The building that decorates does not want rapid move to be moved, best window is large, let flavour come loose to live again first half of the year go in.
As to certain intermediary company " decorate a month, outfit is good rental " behavior, be pair of health that rent a settle or live in a strange place is not responsible.
Man of doctor of family of tumour of hospital of tumour of province of Chemstry Department of acknowledgment Tsinghua university Dr. Sun Yafei, Zhejiang exceeds the support to the article.
