Detection method:
Detection demand time:
It takes 30 minutes/point to detect six items.
Test customer cooperation:
(1) Door and window sealing 12 hours.
(2) Open the cupboard doors and drawers in the room.
(3) Make an appointment one day in advance
Symptoms of indoor pollution:
(1) Eyes, especially cornea, nasal mucosa and laryngeal mucosa have irritation symptoms, and mucous membranes such as lips are dry;
(2) It is easy to get tired, and erythema, urticaria and eczema often appear on the skin.
(3) It is easy to cause headaches and respiratory infections, and often feels chest tightness and suffocation;
(4) Frequent unexplained allergies, dizziness, nausea, vomiting and other feelings;
(5) Pregnant women find fetal malformation in normal pregnancy. After the new relocation or transformation, indoor plants are not easy to survive, and their leaves are easy to wither and wither, making it difficult to grow normally;
(6) After the new move, domestic pet cats, dogs, tropical fish and other animals died inexplicably, and the newly renovated family and office buildings or newly bought homes had irritating smells such as glare and pungent smell.
Test six national standards:
The formaldehyde limit is 0. 1mg/m?
? The limit of benzene is 0. 1 1mg/m?
? Toluene limit is 0.20mg/m?
? The xylene limit is 0.20mg/m?
? The limit of ammonia is 0.20mg/m?
? The limit of TVOC is 0.60 mg/m.
Choose environmental protection standards
(1) Code for Indoor Environmental Pollution Control of Civil Building Engineering (GB50325-200 1( 2006 edition) is a national mandatory standard and must be implemented; Indoor Air Quality Standard GB/T 18883-2002 is a national recommended standard, which is not mandatory, and only has a mandatory role when both parties agree in the agreement that it meets the requirements.
(2) After the decoration is completed, consumers should carry out testing according to the Code for Indoor Environmental Pollution Control of Civil Building Engineering (GB50325-200 1( 2006 Edition)); Indoor air quality should be tested according to Indoor Air Quality Standard GB/T 18883-2002 after the furniture is in place or left for a period of time.
Pollution source:
From the structural analysis, the sources of decoration pollution are ceiling, wall, floor and furniture.
Ceiling: pollutants are putty, concrete and ceiling materials.
Wall: The pollutants are putty, concrete, wall modeling materials, wallpaper, marble and ceramic tiles.
Ground: pollutants are concrete, ceramic tile, marble, plywood, composite wood floor, insecticidal powder, etc.
Furniture: The pollutants are sofa, bed, wardrobe, mattress, cupboard, bookcase, TV cabinet, paint, coating and glue.
Misunderstanding of pollution:
Misunderstanding 1? : totally dependent on short-term ventilation treatment. Ventilation can improve indoor pollution, but the volatilization cycle of harmful substances such as formaldehyde is as long as 3- 15 years, which is by no means a few months' ventilation can solve the problem.
Myth 2? Environmental protection materials do not mean that there is no pollution. The so-called environmental protection material means that the content of toxic and harmful substances is lower than the national standard for this material, indicating that there is no pollution. Due to the cumulative effect of pollution, indoor air quality will not meet the standard, or even seriously exceed the standard.
Misunderstanding 3? It is safe to decorate a room without smell. When the concentration of formaldehyde in the air reaches above 0.40mg/m, we can feel the obvious smell. When we can't smell it, people are easy to relax their vigilance, and we can't judge whether the indoor environment exceeds the standard by the smell. Benzene, which causes leukemia, has a special aromatic smell.
Myth 4? : Over-reliance on simple methods such as disinfectants and green plants. At present, there are various deodorants and disinfectants on the market, but these products are all treated by simple adsorption or masking. The characteristics of plant action are slow speed, long time and very limited absorption. These methods can only be used as auxiliary measures to control pollution.
Myth 5? : only pay attention to formaldehyde. Besides in addition to formaldehyde, there are benzene, ammonia, TVOC (Total Volatile Organic Compounds) and radon. After the transformation, the above toxic and harmful gases must be comprehensively detected.
Myth 6: Choose to go to the hospital when you are sick. Most consumers often only care about whether to go to the hospital when they are sick, and don't think about whether the illness is caused by indoor air quality. It seems that they have spent a lot of money and can't find the real reason, so they have to go to indoor air testing before they can move in.
