Air pollution in new house

Target	Origin	Harm
Formaldehyde	The plywood, the joiner board, center the density fiberboard, the shaving board and so on the man-made plate uses adhesive, man-made plate manufacture furniture; The decoration material like pastes the wall cloth, the wallpaper, the chemical fiber rug, the paint, the coating;	Has the long-term characteristic to the human body harm; Acute is poisoned: The respiratory tract intensely stimulates, the pharynx and larynx is burningly painful, the breath difficulty, the pulmonary edema; The chronicity is poisoned: Is jealous, bursts into tears, the eye itches, the throat dryly itches, the cough, asthma, the sound hoarse, the chest is stuffy, the skin scratches with the finger itches; Long-term contact: Reduces the organism immunity function, causes the neurasthenia, the memory drops, the respiratory tract stimulates for a long time, may cause the lung function to drop;
Benzene	Building material organic solvent, like paint chemical additive and diluent, waterproofing material chemical additive; Decoration material, building board furniture, bond solution;	The blood toxicity, the heredity toxicity and the carcinogenicity, the performance for dizziness, the chest stuffy, disgusting, vomit, is addicted to rests, may be carcinogenic, the initiation blood gets sick with anemia, the central nervous system line of sight is fuzzy; The skin appears the allergic eczema, throat dropsy, bronchitis and the blood platelet drop and so on; The woman menstruation is unusual, gestation period woman pregnancy hypertension syndrome, vomiting during pregnancy with pregnancy anemia, natural abortion and so on, embryo congenital flaw
TVOC	Paint, coating, bond; Man-made foam, plastic plate, textile fiber rug, chemical fiber window blind; Printing ink, duplicator, printer	Stimulates the upper respiratory tract and the skin; The influence central nervous system system, has dizziness, the headache, incapably, the chest is stuffy and so on the symptom; The influence digesting system, appears has a poor appetite, is disgusting and so on; Damages the liver and the lifeblood system;
Ammonia	In the structure construction contains the ammonia antifreeze; The furniture spreads plays the part of uses the chemical additive and the brightening agent	The cough, bursts into tears, pharyngalgia; Serious when may send the toxic pulmonary edema; Breathes the urgent stupor, the shock
Niton	Rock, radioactive natural soil stone; Marble, granite, gypsum and so on;	In room important carcinogen; Forms in vivo radiation, US lists as it induces the lung cancer the most important factor; The long-term decay creates the radiation damage in the human body, induces the lung cancer; May cause newlyweds long-term sterile;

Air pollution in public place

Target	Origin	Harm
New amount of wind	In the room each human of each hour fresh air total quantity work environment each human of new amount of wind must amount to each hour 30 cubic meters	Is in the room which the new amount of wind is insufficient to be easy for a long time to suffer from "the building syndrome", headache, chest stuffy, is easy to be weary New amount of wind insufficient initiation respiratory system and nervous system disease.
Grain	Can enter the respiratory tract in the quality the value diameter is 10 mu M grain, the bacterium, the virus adhere to stick cohere suspended particle, aerosol dust, cigarette smog	The respiratory tract damage, induces the bronchial tube asthma, the bacterium carrier to be easy to cause cancer
Other pollution	In the daily life, the carbon monoxide, the carbon dioxide, the ozone, the cigarette smog (Nicotine), the cleanser (cresol) and so on chemistry pollution matter harm also unceasingly is violating to our organism	The branch adheres to stick cohere middle them on grain is eliminated, majority of can by the induction port lungs. The medicine confirmed these gaseous state sources of pollution are create pneumonia, bronchitis, the old disease main reason

Air pollution in vehicles

Pollution origin and harm

In the vehicle the air pollution main origin the glue water, the textile, the plastic fitting which in quarter and so on chair, ceiling of a shed uses and so on in each kind of vehicle decorates the virulent gas which the material volatilizes, including benzene, formaldehyde, total volatile organic matter, ammonia and so on

Symptom

"fills in which according to the user scene new vehicle user healthy question examination table",30% person has the dizziness symptom,20% person in the automobilism process perforated to stimulate the symptom, but also has the surveyor was many indicated has the skin to be dry 瘙 itches, the pharynx and larynx stimulates, the stuffy nose flows situation and so on tears

Realistic condition

According to the traffic department and the measurement quality examination research institute statistics, has stochastically spot-checked the use insufficient half year new vehicle, finally discovered in 70% automobile vehicle the noxious gas density surpasses in the country husband and wife the air quality specification, is highest may surpass above standard 10 times

Data analysis

The multitudinous examination result indicated that, vehicle newer, the unqualified probability is higher
Is examined in the vehicles, the formaldehyde exceeds the allowed figure occupies was measured the total 32%, within year purchases the new vehicle has accounted for 66.7%. Similarly, TVOC exceeds the allowed figure in the vehicle, uses does not account for 71. a year new vehicle4%.
1 last year purchased the new vehicle, examined the TVOC index is 8. unexpectedly76, surpasses the national standard 0.50 indices 16 times. are many And some 2 last year purchased automobile TVOC respectively achieved 3.14 and 3.02, surpasses above national standard 5 times.

Thorough analysis

Source of pollution Yu Xinche itself:Very many automobiles got down the production line on to enter the market directly, in each kind of fitting and the material noxious gas has not obtained the sufficient release, created in the vehicle directly the air pollution;
The pollution originates in the vehicle decorates:After the most consumers buy the vehicle all to have to enter in the driving to decorate, some dealers also will buy the vehicle to deliver the decoration to take the favorable condition, will cause some to include the deleterious substance the place sleeve, the adhesive enters in the vehicle, the varying degree will create in the vehicle the air pollutionIn the vehicle the leather and the repair uses the material, the leather oil, each kind of cleansing agent, all are creates in the vehicle the air pollution main originThese materials the residual chemical additive can release in the processing process in the automobile use process, causes the harm to the human body health

In vehicles environment characteristic

In vehicle space relatively narrow and small, 空气量 limited, airtight good, the winter summer two seasons, the driver generally can turn on in the vehicle in particular the air conditioning, if in the vehicle pollutant release density is high, then will have the greatest hidden danger regarding the driver and passenger's health

International convention

Some materials demonstrated that, starts from on century 890 ages, European many countries on already noted to the vehicle in the air pollution question; The German environmental protection organization and the automobile manufacture company coordinated has formulated in the automobile vehicle the environment standard, caused in the vehicle each kind of noxious gas density and the content had the explicit limit, like this not only let the consumer feel relieved, also let the automobile manufacture enterprise have a legal basis; Country and so on America, date, Han also afterwards follows up.

Consults the news most newly

In order to formulate in the vehicle the environmental pollution control standard to do ahead of time prepares, the related department had decided developed in the "China automobile in the national scope the environmental pollution situation to investigate the" activity for the first time, estimated in July, 2004 ahead of time will appear "In the Chinese Automobile Environmental pollution Situation Investigation Newspaper the German government science and technology also regarding this to continue to track For the first time"

The case returns puts

In August, 2002, the Beijing resident Mr. Li's wife in purchases a new vehicle for month because the leukemia unfortunate died in the next year March Mr. Li enters in the driving in the indoor environment monitor center the air examination, after confirmed in the vehicle the benzene exceeds the allowed figure ( benzolism to be possible to cause diseases to regenerate barrier anemia) when soon this vehicle sales company company considers the court
