With the improvement of people’s living standards, more and more attention has been paid to household pollution. In all household pollution, whether or not formaldehyde emissions meet standards is of particular concern. Many consumers in the decoration and purchase of household products will first ask “Do you have formaldehyde release standards?†Searching the Internet for “formaldehyde†results in millions of instant results. Whenever you mention formaldehyde, everyone’s first impression is toxic. , cancer, leukemia ····· As a result, people choose home formaldehyde detector, governance company door-to-door governance, purchase purifiers, for cost considerations, many people are choosing to buy formaldehyde detection equipment on the Internet, self-test home of formaldehyde is exceeded, but the test results are reliable ? Home decoration formaldehyde pollution harm According to the test data, 68% of the indoor decoration materials found to be harmful gas pollution. When these materials enter the house, they will produce "five killers" such as formaldehyde, benzene, total volatile organic compounds (TVOC), ammonia, and helium. Formaldehyde, a colorless, highly irritating gas, has been identified by the World Health Organization as a carcinogenic and teratogenic substance. Formaldehyde release pollution, will cause eye tears, cornea, conjunctival congestion and inflammation, skin allergies, nasopharyngeal discomfort, cough, acute and chronic bronchitis and other respiratory diseases, respiratory inhalation, but also cause liver and lung function, decreased immunity and so on. According to experts, in the process of renovating the house, if the owner clearly feels irritating odor and tears in his eyes, or he has dizziness, colds, and energy loss after exhaustion, it is likely that excessive formaldehyde causes the body. Unwell reaction. In addition, formaldehyde can also be detected to a certain extent by observing animal and plant reactions. For example, it is found that plants have died of wilting, pets have been sick, food is not eaten, and energy has declined. This proves that there is a problem in the living room. At this time, it is necessary to maintain good indoor ventilation, and check whether indoor formaldehyde exceeds the standard through the instrument. Self-testing formaldehyde data can only be used as a reference A surnamed staff member of the Guihua Construction Engineering Test Center in Guizhou told reporters that there are many causes of formaldehyde, one is from artificial boards such as plywood and large core boards, and the other is from building materials, interior decoration materials, decorative paints and adhesives. in. The formaldehyde detection instrument purchased by the owner is used to detect formaldehyde through the sensitivity of the built-in electro-optical sensor. If the sensor is of poor quality and insensitive, the result will be an error. The formaldehyde content will be measured based on the color change of the liquid and the color card. The exact value cannot be measured, and the detection of the specific formaldehyde content is related to the conditions of humidity, temperature, and pressure. Many household items are placed in a relatively narrow space, resulting in the formation of formaldehyde products that meet the standards. Accumulation, and the detection of a single instrument simply cannot confirm the formaldehyde emission of the entire space, so the results of the self-tested formaldehyde data can only serve as a reference. The reporter learned that professional formaldehyde testing agencies and testing products need to be certified by quality supervision and measurement units. Professional testing organizations need to have China Metrology Accreditation (CMA) mark, which is the most basic necessary qualification for indoor air quality testing organizations. It must also have a national laboratory certification, that is, it has the “CNAL†mark and only has this With the two marks, the test reports issued by them are legally efficient, and they are the guarantees for the owners to safeguard their own rights and interests. Consumers can select and regulate companies based on these two certifications.
