Eight misunderstandings of decoration pollution

myth 1: as long as you can't smell the smell, you think that the indoor environment is not polluted. Among the major harmful substances that cause indoor environmental pollution, formaldehyde, ammonia, etc. have a strong pungent smell, which is easy for the human body to feel. Radioactive substances such as radon are colorless and tasteless, which is not easy for human body to feel, but it does great harm to people. Radon exists in building cement, slag bricks, decorative stones and soil. Its main harm to human body is to cause lung cancer, which is the second major cause of lung cancer besides smoking

foreign countries have always attached great importance to the harm of radon, a radioactive substance, to human body. In the United States, when building new houses, relevant departments will measure radon in the soil of the site to judge the level of radon content in the area. If it exceeds the standard, the builders will be advised to relocate to avoid high radon areas. The United States also designated the third week of October as radon awareness week to remind people of the dangers of radon

Myth 2: as long as the materials used in decoration are up to standard, there must be no indoor pollution.

when decorating, using up to standard materials is only the most basic requirement, but if the design and technology are unscientific, it will also cause indoor environmental pollution. For example, when decorating the floor, experts will suggest that you had better not lay all wooden floors, or all floor tiles. Instead, some rooms should be paved with wood floors, while others can choose floor tiles. Because even if the materials you choose are up to the standard, using a large number of wooden floors per unit area is likely to cause formaldehyde to exceed the standard, while using floor tiles in a large area may cause radioactive substances to exceed the standard

myth 3: only pay attention to decoration, ignoring the indoor pollution caused by furniture

in March 2006, a teacher Yang of a university in Beijing ordered a set of bedroom furniture worth 6400 yuan. On April 2, when the furniture was transported home, I smelled a strong pungent smell emanating from the furniture. As the weather warms, the smell becomes stronger and stronger, especially in the bedroom where this set of furniture is stored. It is impossible to live with the window open. In less than a month, teacher Yang's family felt unwell. After testing, it was found that the formaldehyde content in the air in the room where the furniture was stored exceeded the standard by more than 6 times

in addition to hard furniture, some soft furniture such as mattresses and sofas will also cause indoor environmental pollution. Now, people know black core mattresses, but many people don't know black core sofas. Not long ago, inspectors found in a furniture city in Beijing that some noble and gorgeous sofas were full of broken sponges glued together. Most of these viscoses contain heavy formaldehyde and benzene. Wrapped in luxurious leather and cotton jackets, these broken sponges slowly emit harmful gases, which poison people's health and lead to excessive radioactive substances

myth 4: only pay attention to the family environment, do not pay attention to the pollution of other public places

in the early summer of 2006, employees in the Beijing Office of an American law firm generally reported headache, tightness, dry mouth and tears, which seriously affected their normal work. On June 28, the Institute commissioned a monitoring agency to conduct testing, and the results showed that due to decoration, the formaldehyde content in the air in its office exceeded the national standard. In the case of unsuccessful negotiation with the decoration company, the office formally submitted an arbitration application to the China International Economic and Trade Arbitration Commission. As a result of the arbitration, the decoration company refunded 20% of the decoration money and interest of the law firm, totaling 230000 yuan. Formaldehyde pollution in the office of the law firm was eliminated within two years from the date of the arbitration, and all arbitration fees and lawyer fees were borne by the decoration company

in addition to offices, some entertainment places, shopping malls, conference halls, etc. have varying degrees of air pollution. Do not stay in these places for too long at a time, and try to avoid the peak flow of people

myth 5: pay insufficient attention to household appliances, biological mold and other pollution

in addition to the indoor air pollution caused by building materials, decoration materials and furniture, household appliances, office equipment and biological mold are also important factors causing indoor environmental pollution, especially mold pollution has not attracted enough attention, and its harm is very serious. For example, in the United States, children in a certain area died inexplicably one after another. It was found that it was caused by mold growing on the wall

myth 6: only knowing that ventilation can clean the air, but I don't know how to ventilate reasonably

experts point out that 9 a.m. to 4 p.m. is the best time to open windows for ventilation. During this period, due to the relatively high temperature, pollutants in the air are easy to be distributed, and the outdoor air is relatively clean. At the same time, some pollution sources also need to reach a certain temperature before they emit harmful gases. Therefore, ventilation during the high temperature time of the day is more conducive to the removal of indoor pollutants

myth 7: I know that purifiers can purify air, but I don't know how to use them reasonably

not all air purifiers work. Even if products pass the inspection, they should also be selected according to their actual situation. Different products should be selected to remove different pollution. If they are not used properly, they will not only not remove the pollution, but also likely cause secondary pollution. Therefore, before buying an air purifier, you must find out what the indoor pollution source is, and read the product manual in detail, or consult relevant experts

myth 8: know the indoor environment should be tested, but don't know what kind of testing unit to choose

according to relevant regulations, the unit that carries out indoor environment testing must be approved and obtain the corresponding testing qualification; The testing personnel must be trained and pass the examination before obtaining the testing qualification certificate. Now there are many units in the society that claim to be able to test the indoor environment. Consumers must enhance their awareness of self-protection, and decide whether to entrust them with testing after checking the qualifications of testing units and testers
