The pollution caused by the indoor decoration has attracted more and more attentions from people. The indoor decoration has always induced various diseases. Although there is no medical proof to prove the relationship between the pollution of indoor decoration and the formation of various diseases, the pollution of indoor decoration is at least one of main reasons of causing diseases. 

According to the experts, most decorative materials contain organic substances like formaldehyde and benzene. The pollution caused by the indoor decoration can not be avoided. The reasons of causing indoor pollution are diverse, such as the decorative materials and furniture. The materials for indoor decoration like flake board and paint all contain the toxic substances including formaldehyde and benzene. If these substances are absorbed by the human body, they can cause various diseases like high blood pressure.

Generally speaking, the indoor pollution is mainly contained in three kinds of household articles, namely, furniture, floor board and decorative materials for wall. Furniture is a main source of formaldehyde. The long-term absorption of formaldehyde can seriously stimulate the respiratory system and probably cause cancer and fetal abnormality. When people choose the materials for the floor, they should pay attention to the content of formaldehyde, the strength of the board and the functions of preventing insect and resisting corrosion. The decorative materials for wall also contain toxic substances. For example, the emulsion paint is usually composed of water, paint and emulsion. These raw materials do not contain toxic substances. The toxicity is produced by the ethylene glycol in film-forming agent and organic mercury in mildew preventive. Therefore, it is safe for people to use emulsion paint with high quality.

Although the indoor pollution can seriously endanger the human health, there is no need for people to worry about the decoration too much. The harms can be strictly controlled as long as people choose environmental-friendly decorative materials and find out the pollution source. At the same time, people should moderately adjust the humidity and temperature inside the house. The speed of release of toxic substances keeps a close relationship with the humidity and temperature inside the house. In addition, people should not decorate the house if someone at home is pregnant, or the healthy growth of fetuses can be affected. After the decoration, ventilation should be well maintained, as ventilation can accelerate the release of toxic substances so as to reduce the indoor pollution to the full extent.
