Qualified products are also polluted beyond the st

Choose a regular decoration company and use qualified environmental protection materials. Indoor air pollution still exceeds the standard - the disaster caused by excessive decoration

Mr. Di's house has been decorated recently, and the decoration cost of the 110 square meter house is nearly 100000 yuan. But after moving to his new house, Mr. Di felt that the beautiful house was always filled with an unpleasant smell. He asked quality inspectors to test and found that the indoor formaldehyde, benzene and other harmful gases exceeded the standard, and the air pollution in the colorful children's room exceeded the standard even fourorfive times. "I use qualified products, and the decoration company is also formal. Why would it exceed the standard?" After learning the test results, Mr. Di was puzzled

overdesign is a major factor in decoration pollution

Mr. Di originally planned to use 60000 yuan to simply decorate the house, but when discussing the decoration plan with the designer, he couldn't resist the lobbying of the designer and the temptation of gorgeous design renderings. He agreed to build a large TV cabinet, build a beautiful bar and luxury wine cabinet between the living room and the dining room, and add a bedside background wall to the master bedroom, The decoration of the children's room is becoming more and more complex...

Mr. Di found that with the suggestion of the designer, there are more and more decoration projects in his family. 60000 yuan soon "couldn't be covered", and it cost nearly 100000 yuan to finish the decoration. Originally, it was acceptable to decorate the house more beautifully and spend more money, but now it seems that this decoration has caused serious indoor pollution and may also cause harm to the family's health. Don't mention how regretful Mr. Di is

Gong Dewei, senior engineer of Shaanxi interior decoration project quality supervision and inspection station, has been responsible for indoor air detection for five or six years. He told reporters that excessive decoration and excessive use of plates may cause excessive concentration of pollution sources, resulting in excessive indoor air pollution. Behind the luxurious decoration, there may be serious indoor air pollution. Like Mr. Di, there are not a few people who "go through all the trouble" to decorate the house, which has become a relatively common problem. Industry insiders pointed out that over design not only caused decoration waste, but also caused decoration pollution

qualified materials are not absolutely safe and harmless

many consumers believe that as long as qualified materials are used, indoor air can be guaranteed to meet the standard. In this regard, Gongdewei pointed out that this is a misunderstanding. Gongdewei said that using qualified materials for decoration cannot necessarily meet another national acceptance standard related to air quality, namely the "code for indoor environmental pollution control of civil construction projects". The content of harmful substances in indoor air is determined by the total amount of harmful substances in all decoration materials (including furniture). In the process of interior decoration, coatings and adhesives are indispensable. At the current level of science and technology, formaldehyde, benzene series and other organic volatiles are essential to ensure the performance of coatings and adhesives, and they are also the source of indoor air pollution. The national standard stipulates the "limit value" of the content of harmful substances in materials, but these allowed products still contain a certain amount of harmful substances, which are not absolutely safe and harmless products

the example of Mr. Di's family is quite clear. Although every material he uses is up to the standard, because too many materials are used in a limited space, the total amount of harmful gases emitted exceeds the standard, and the indoor air naturally cannot meet the standard. Without controlling the total amount of decoration materials, it is impossible to ensure that the air quality meets the standard

according to Gongdewei, the detection of indoor air mainly includes five indicators: formaldehyde, benzene, ammonia, TVOC (volatile organic compounds) and radon. These harmful gases may cause cancer, mainly from excessive decoration and unqualified decoration materials. The source of the first few harmful gases exceeding the standard is mainly man-made boards, which should be used as little as possible; The products that cause excessive radon of radioactive substances are mainly marble and granite. Consumers must choose products suitable for indoor use when purchasing
