--formaldehyde. Mainly from artificial plates, it will stimulate people's respiratory system, causing laryngopharyngitis, asthma and other diseases, and is classified by the World Health Organization as a suspected carcinogen. According to our country's regulations, the concentration of formaldehyde in living rooms cannot exceed 0.08 mg/m3.
- Benzene series. Including benzene, toluene and xylene, etc., mainly found in paints, adhesives and various interior wall coatings. Benzene can damage the body's hematopoietic function, cause blood diseases, and can also cause cancer. It has been identified by the World Health Organization as a carcinogen. The “Hygiene Code for Indoor Air Quality†formulated by the Ministry of Health in 2001 stipulates that the standard for benzene in indoor air is less than 0.087 mg per cubic meter.
- Ammonia. Indoor ammonia mainly comes from concrete antifreeze. Ammonia mainly causes damage to the respiratory tract, mucous membranes, and skin of the human body, causing symptoms such as tears, headaches, and dizziness. In 2001, the “Code for Indoor Environmental Pollution Control of Civil Construction Projects†stipulated that the concentration of ammonia in indoor air was less than 0.2 mg per cubic meter.
--radon. It exists in building cement, slag bricks, decorative stone and soil. Radon is a radioactive substance, and its main hazard to the human body is to cause lung cancer. According to reports, wolfberry is the second largest cause of lung cancer besides smoking. The national standard for the content of antimony in China is: the new house is less than 100BQ/m3; the old house is less than 200BQ/m3.
In addition, the radioactivity of building materials can also cause radiation harm to the human body. This is mainly a radioactive material produced by decay of radioactive elements such as radium, thorium and potassium in natural stone. According to the relevant provisions in the "Restriction of harmful substances in interior decoration materials", according to the radioactive level of the decoration materials, the natural stone products are divided into three categories: A, B, and C. The interior decoration should be A-type stone.
Misunderstanding of home decoration
Scientifically determine the decoration design program. Even if it is a qualified product, it is better not to use a material in a large area, especially the floor material of the room. Must take into account the carrying capacity of space, otherwise it may cause damage due to excessive accumulation of certain harmful substances. The decoration design of the room should not use a large amount of color paint for one-sided pursuit of color to prevent indoor lead pollution.
Scientific selection of construction process. In addition to special requirements, generally do not lay large core boards under the compound floor; correctly choose the wall closure material; use big core board to fight the cabinet and package heating cover, which must be closed with formaldehyde sealant, it is best not to have Bare place; the best choice for paint is thicker film and better sealing.
Science and reasonable check-in. Do not rush to stay in the newly renovated house. Ventilate indoors for a period of time, usually in a month or so, and wait for the release of harmful gases. If conditions permit, the indoor environment inspection department should be invited to conduct inspections first, listen to the opinions of experts, and take scientific measures for the problems that arise to determine the appropriate check-in time.
