Current situation of pollutant limitation standard system for decorative and construction materials in China

In order to ensure the indoor environmental quality,China has established a standard system mainly based on two categories of standards related to pollutant limitation for decorative and construction materials.One category aims to directly control the content or release of pollutants in building materials,focusing on the physical and chemical properties of the building materials themselves.The other category aims to optimize the selection of building materials through the pre-assessment of indoor pollutant levels,focusing on preventing indoor pollution through the reasonable selection of building materials.The characteristics and scope of application of these two categories of standards are analysed,and it is pointed out that the future direction lies in the “prevention control” approach that targets the overall level of indoor pollutants.Suggestions for the development of standards related to pollutant limits for decorative and construction materials in China are proposed to strengthen the formulation and implementation of the pollutant limitation standard system,thus safeguarding the indoor environmental quality and people’s health.
