Detection does not have money, the product does not protect the owner of the home of book city road Miss Wang found a certain technology company on the Internet a few days ago, the company claims to provide the qualification to control home gas pollution, but also free on-site detection of violations. One call, two employees took a portable formaldehyde detector home. They turn around that turn and give results in less than 10 minutes, saying that Ms. Wang’s home has exceeded the formaldehyde standard by 10 times.
You know, this over-standard method may completely lead to a child suffering from leukemia, Miss Wang was shocked. At this time, the other party proposed that the air purifiers and detergents produced by their company are very easy to use. As long as they persist for ten days and eight days, the pollution can be eliminated. Frightened Miss Wang flew out and bought more than 600 yuan on the spot.
Who knew that the test was also detected and the product was bought. Half a month later, the quality of the air in the home was not changed at all and it was still filled with pungent sourness. Ms. Wang discovered that the so-called professional cleaners are just ordinary detergents—or they are against the water.
It is best to find a third-party testing agency that “since it is necessary to sell its own products, the testing process is difficult to maintain objectively.†Testing and governance are best divided into two steps. He said that the formal indoor pollution testing agencies must pass the certification of the metrology department of the quality supervision department above the provincial level and hold the CMA certificate and project acceptance capacity table. Only they can open a test report with legal validity. According to information exchanged by industry peers, there are currently only dozens of institutions such as Shenzhen.
Liu Yue said that currently the detection method used in the professional field is spectrophotometry. The testing institution must be equipped with professional equipment such as spectroscopic laboratories and gas chromatographs. Usually, the collected gas samples are brought back to the laboratory for further study. It is almost impossible to give a full and complete report on the spot. If you believe in a portable instrument, then the owners will have to keep an eye on it. He suggested that when looking for a testing unit, it is best to go to the website of the Guangdong Provincial Bureau of Quality and Technical Supervision to check whether it has been certified for filing, and the owner can also directly ask the other party to issue a CMA certificate and project acceptance capacity table to distinguish between true and false.
A full set of fees of around 2,000 yuan Since there is no lunch, then what is the full set of testing fees for regular operations? The reporter contacted the Shenzhen Indoor Environmental Quality Monitoring Station, which is a designated laboratory for indoor environmental quality monitoring approved by the Shenzhen Municipal Environmental Protection Department and certified by the Guangdong Provincial Bureau of Quality and Technical Supervision. Du Shuren, director of the inspection department, explained the charging method in detail.
Home indoor air quality inspection items generally include formaldehyde, benzene, toluene, xylene, total volatile organic compounds TVOC, and stone radioactive materials. According to national standards, each individual room is less than 50 square meters and set up 1-3. Then a set of 100 square meters of the house to complete the above-mentioned full set of tests, the cost is probably between 1500-2000 yuan.
Du Shuren said that sampling and testing generally take three working days. At the same time when the inspection report is given, the agency will also provide solutions for the owner's reference.
The consumer survey asked for a strong contempt for the guerrillas, Gary, male, 26 years old. The media practitioners are now so hot that they can't often ventilate their windows, so I'm looking for a testing agency to help. Before the renovation was also a bubble in the decoration forum for a while, found that everyone's detection of indoor air pollution, most of the doubts. I think the demand must exist, but I am worried about hitting a liar. However, I am confident that everything is available on the Internet. Which unit has a certificate and a good word of mouth will come out.
Do not ask for help Jeason, male, 27 years old, administrative staff I will not go to the professional agency to test, more than 2000 yuan is too expensive. In terms of the psychology of an ordinary consumer, there are odors in newly-renovated houses, and many will open doors and windows to release odors. It is not surprising that, because of the decoration materials, those paints and wood products will emit smells. If ventilation does not solve the problem after a period of time, I will look for decoration materials suppliers and ask them to provide professional inspection reports.
Anti-pollution DIY Tips A pot of spider is equivalent to an air purifier â— Normally open doors and windows, to maintain air circulation is essential. Even if there is no excessive formaldehyde or benzene in the home, the body exhales about 500 liters of carbon dioxide per day, and there are more than 200 organic substances such as lactic acid emitted from the skin. Therefore, it must be ventilated.
â— The cooker hood is often turned on regardless of cooking or boiling water.
â— Lower the lid when the toilet flushes. Try not to open it when not in use.
â— Use air purifiers. Such as the refrigerator can use the deodorant refrigerator, wardrobe can be placed moisture absorbent, if pregnant women and children at home, you can put them in front of the bed or pillow, charcoal bag and so on.
â— If there is air conditioning, it is best to add another ventilator to keep the indoor air fresh.
â—Place green plants. Such as aloe vera, tiger-tailed orchid, spider plant, ivy and so on. They have a strong ability to absorb and destroy harmful gases such as formaldehyde, hydrogen sulfide, trichloroethylene, and benzene in the house. For example, Chlorophytum, in a space of 10 square meters, the function of a potted plant is equivalent to an air purifier.
â— Use crude fiber tropical plants to absorb gas, such as pineapple, pineapple, and so on. Lightly rubbing wooden furniture with citric acid can effectively remove paint odors.
