The Comprehensive Emission Standards for Air Pollutants (-1996) In May 2010, China issued the Notice of the Environmental Protection Department on the Guidelines for Promoting Joint Prevention and Control of Air Pollution to Improve Regional Air (Guobanfa [2010] No. 33), which, for the first time, put forward the importance and necessity of carrying out the prevention and control of VOCs pollution at the national level.

Local Standards

The original Comprehensive Emission Standards for Air Pollutants (-1996), which only limited the emission concentrations of benzene, toluene, xylene, and phenols and formaldehyde, was followed by the Emission Standards for Air Pollutants from Coke Ovens (-1996), Emission Standards for Catering Fumes (-2001), Emission Standards for Air Pollutants from Oil Storage Depots ( -2007), Emission Standards of Air Pollutants for Gasoline Transportation ( -2007), Emission Standards of Air Pollutants for Gasoline Stations ( -2007), Emission Standards of Pollutants for Synthetic Leather and Artificial Leather Industry ( -2008) and Emission Standards of Pollutants for Rubber Products Industry ( -2011) increased the emission limit values for BaP, VOCs of oil fumes, VOCs of oil and gas, and VOCs of synthetic leather and artificial leather Industrial VOCs emission limits. For malodorous pollutants, the "Emission Standards for Malodorous Pollutants" (-1993) was introduced to regulate pollutants emitting malodorous odors such as mercaptans, sulfur ethers, amines, and other pollutants (most of which are volatile organic compounds (VOCs)). In terms of local control standards, Beijing, Shanghai, and Guangdong Province are at the forefront of developing stringent emission control standards for VOCs. The specific items to be controlled in the standards have been expanded vocs emission standards vocs emission standards, but compared with foreign countries, the control is still relatively loose.

①Beijing: "Refining and Petrochemical Industry Air Pollutant Emission Standards" (DB11/447-2007), "Comprehensive Emission Standards for Air Pollution" (DB11/501-2007).

② Shanghai: "Semiconductor Industry Volatile Organic Compounds Emission Standards" (DB31/374-2006)

③ Guangdong Province: "Furniture Manufacturing Industry Volatile Organic Compounds Emission Standards" (DB44/814-2010), "Packaging and Printing Industry Volatile Organic Compounds Emission Standards" (DB44/815-2010), the Emission Standards for Volatile Organic Compounds in Surface Coating (Automobile Manufacturing Industry) (DB44/816-2010), Emission Standards for Volatile Organic Compounds in Footwear Manufacturing Industry (DB44/817-2010), and so on.

Paint voc national standard value is how much

State Environmental Protection Administration of the latest release of water-based interior paint environmental labeling product certification requirements, VOC shall not be higher than 100 grams per liter. The Beijing Municipality formulated the "indoor decoration paint safety and health quality evaluation rules", the VOC requirements must be below 125 grams per liter.

Foreign developed countries have very strict limits on VOC content in paints. In terms of the European Union, a class (matte class) coatings must not be higher than 30 grams per liter, and the second class (light class) must not be higher than 200 grams per liter.

Paint national standard "-2001 interior decoration materials in the paint of harmful substances in the limit" in the VOC content is defined as: "paint in the total volatile matter content minus the moisture content, that is, the paint in the volatile organic compounds content." Generally speaking, the less VOC contained in the material, the less harmful it is to the human body.
