Decoration pollution: mainly by the materials used in the decoration process and indoor furniture caused by gas pollution, including formaldehyde, benzene, toluene, tvoc, ammonia and other harmful gases。There are many sources of indoor environmental pollution, a considerable part of which is caused by improper materials used in the decoration process, including volatile organic compounds such as formaldehyde, benzene, xylene。

　　Nowadays, with people's increasing concern for health, environmental protection has become the primary consideration for home decoration。According to the survey, 2.8 million people around the world die directly or indirectly from decoration pollution every year, and decoration pollution has been listed as one of the five major environmental problems that harm the public。About 66% of a person's life is spent at home, so poor indoor air environment will cause direct harm to people's health。Among the many decorative materials, toxic materials account for 68%, which can produce more than 300 volatile organic compounds (VOCs) and cause more than 30 diseases。Among them, the elderly and children are vulnerable because they spend a lot of time indoors。The serious pollution in home decoration is formaldehyde。At present, major brands have launched green health products, mainly to reduce the content of formaldehyde。However, according to the report, the release period of formaldehyde at home can be as long as 3 years or at least 5 years, so it is imperative to improve people's awareness of prevention and effectively reduce the harm caused by indoor formaldehyde。

　　Decoration pollution detection and control: refers to the detection of these decoration pollution through various methods, and control through relevant measures to reduce or even eliminate the harm of these decoration pollution, so as to protect the residential health of residents。

　　The necessity of inspection and control of decoration pollution

　　Nowadays, human beings are facing the third environmental pollution after soot pollution and photochemical smog pollution, mainly indoor air pollution。American experts have found that there are more than 500 kinds of volatile organic compounds in the indoor air, including more than 20 kinds of carcinogens and more than 200 kinds of pathogenic viruses。The main hazards are radon, formaldehyde, benzene, ammonia, esters, trichloroethylene and so on。A large number of shocking facts have proved that indoor air pollution has become an "invisible killer" endangering human health, and has also become a common concern of all countries in the world。Studies have shown that indoor air pollution is 2-5 times more serious than outdoor air, and can reach 100 times in special cases。

　　Therefore, the United States lists indoor air pollution as one of the five environmental factors that endanger human health。The World Health Organization also lists indoor air pollution, high blood pressure, hypercholesterolemia and obesity as the top 10 threats to human health。According to statistics, nearly half of the world's people are exposed to indoor air pollution, and indoor air pollution has caused 35 percent.7% of respiratory diseases, 22% of chronic lung diseases and 15% of bronchitis, bronchitis and lung cancer。
