Winter decoration and environmental protection

Mr. Sun Xiwan Road: Home decoration should focus on environmental protection. May I ask what kind of decoration is environmentally friendly? Is there a specific standard& nbsp;& nbsp;
Expert: Environmentally friendly home decoration refers to indoor air containing harmful substances that meet or fall below the prescribed limit. The formaldehyde value is 0.08 mg/m3, ammonia is 0.2 mg/m3, benzene is 0.09 mg/m3, TVOC is 0.5 mg/m3, and radon is 200 beck/m3& nbsp;& nbsp;
Ms. Guo from Daqing Road: When I decorated my house, I chose many environmentally friendly materials. How come there is still air pollution after the decoration is completed? May I ask why some environmentally friendly products are not environmentally friendly& nbsp;& nbsp;
Expert: Some environmentally friendly materials are used in various ways to prove that the product is environmentally friendly in promotion, but they are rarely used or false, leading to misunderstandings as environmentally friendly decoration and misleading consumers. Or if a single product meets environmental protection requirements, but many products are placed together and the environmental indicators exceed the standard, it belongs to superimposed pollution
