People live and work indoors most of their lives.The phenomenon of environmental pollution caused by indoor decoration causing illness, disability, and death has become a social problem. Indoor environmental pollution has been included in one of the “top ten killers”. These polluted gases have been scientifically proven to have a great impact on the human body and can easily lead to respiratory diseases, cancer, leukemia, and neurological diseases, especially for pregnant women, children, and the elderly. Serious harm.Premier Wen Jiabao specifically instructed that “this matter is related to the health of residents and should be paid attention to.”

Generally, people are used to ventilation for two months after renovation, and then check in.However, indoor decoration pollution is mainly formaldehyde, benzene and other chemical pollutants. The release period of such pollutants is up to 15 years, and the problem can be solved in two months. In closed rooms with air conditioning in midsummer and heating in winter, due to the lack of outdoor fresh air, the harm is even more serious!If it is an office or business place, it is even more impossible to be vacant for two months. It is often a rush to enter the office and open for business. This will inevitably bring great health threats to both employees and customers, and it will also affect office efficiency and operating income.Dear citizens and friends, when you are in a newly renovated new home or a new office, hotel, conference room, furniture shopping mall, building materials market and other places for a long time, will you have headache, dizziness, cough, chest tightness, nausea, vomiting and other symptoms, these are the signs of the invisible indoor killer-“formaldehyde”.The main pollution of the indoor environment comes from materials such as buildings, decorations, and furniture, including formaldehyde, benzene, and ammonia pollution. Among them, formaldehyde pollution is the most harmful to human health.

Formaldehyde is a colorless, irritating and water-soluble gas. It has the effect of coagulating protein. Its 35%-40% aqueous solution is commonly called formalin. It is often used as a solution for soaking specimens. Formaldehyde is a highly toxic substance. Formaldehyde ranks second on the control list of toxic chemicals in my country. According to Japanese studies, the release period of indoor formaldehyde is generally 3 to 15 years.

Formaldehyde has been identified by the World Health Organization as a carcinogenic and teratogenic substance. It is a recognized source of allergies and one of the potential strong mutagens. Studies have shown that when the indoor concentration reaches 0.01—0.06mg/m3 per cubic meter of air, children will develop mild asthma. When the formaldehyde content in the indoor air is 0.1mg/m3, there will be odor and discomfort. When it reaches 0.5mg/m3, it can irritate the eyes and cause tears. When it reaches 0.6mg/m3, it can cause throat discomfort or pain. The concentration is 0.1mg/m3. When the formaldehyde content is 0.1mg/m3, there will be odor and discomfort. When it reaches 0.5mg/m3, it can irritate the eyes and cause tears. When it reaches 0.6mg/m3, it can cause throat discomfort or pain. At higher levels, it can cause nausea, vomiting, cough, chest tightness, asthma, and even pulmonary edema. When it reaches 30mg/m3, it will immediately cause death.

According to surveys and statistics, 2.8 million people in the world die directly or indirectly from decoration pollution every year. Decoration pollution has been listed as one of the five most harmful environmental problems to the public. According to data provided by the Chinese Academy of Preventive Medicine, people spend an average of 66% of their time at home. Therefore, poor indoor air environment will cause the most direct harm to human health. Among them, the most vulnerable are the elderly and children, because they stay indoors for the longest time, especially children who like to sit on the floor.

How to prevent formaldehyde pollution to the indoor environment: 1. Pay attention to indoor air circulation and lighting, and plant a variety of flowers and plants with adsorption effects. 2. Pay attention to the detection and purification of formaldehyde in the city.3. Formaldehyde purification and treatment during the decoration process. [6]
