A spot check of interior decoration materials by relevant state departments shows that 68% of the materials are polluted by toxic gases, and more than 300 kinds of toxic substances will cause various diseases once they enter the home and volatilize. Even if the decoration materials are environmentally friendly products, the superposition of harmful substances released by various furniture and decoration materials will also cause serious pollution. The indoor air is certain, and the degree of environmental pollution caused by using one wood material and ten wood materials is completely different. Coupled with the adhesive used in decoration, decoration pollution is inevitable.
It is unscientific and inaccurate to distinguish whether there is pollution in the room only by smell. Some of the toxic and harmful gases are odorous, such as benzene: aromatic, formaldehyde: pungent, ammonia: urine. But there are also colorless and odorless ones, such as TVOC and radon. But it is difficult to distinguish the complex smell of various chemicals mixed together. Therefore, it is inaccurate to judge whether there is pollution or what pollution by smell, that is to say, the polluted person may not be able to smell the smell, and the person who smells the smell may not be polluted. Harmful gases such as benzene and formaldehyde in indoor air can cause serious diseases even if they exceed the standard slightly. In a decorated room, sometimes, if you can smell the obvious smell of formaldehyde or benzene, the pollution is very serious. But when you can't smell it, you can't say that pollution doesn't exist.
People spend about 70% of their life indoors, with an average daily intake of air 12 cubic meters, while urban residents spend about 70%-90% of their time in various indoor environments. You can imagine how important indoor air testing is to people's health. A scientific research achievement of the US Environmental Protection Agency shows that indoor air pollution is generally 2-5 times more serious than outdoor air pollution, and it can reach 100 times in special circumstances. The National Academy of Sciences estimates that the annual medical expenses caused by indoor air pollution in the United States are about 654.38+05 billion to 654.38+00 billion dollars. Indoor air pollution is considered as one of the five environmental factors that endanger public health. For the health of you and your family, it is necessary to be a indoor air testing.
