Foreword
According to the "Environmental Protection Law of the People's Republic of China" and the "Atmospheric Pollution Prevention and Control Law of the People's Republic of China". In order to improve ambient air quality, prevent ecological damage, create a clean and suitable environment, and protect Human health, this standard is specially formulated. This standard will be implemented from October 1, 1996, and will replace GB3095-82. This standard has changed in the following contents and chapters: Standard name,
-~3.1~~3.14 (definitions of 14 terms added); -4.1→4.2 adjusted the relevant content of partitioning and classification); -5 (Added and adjusted pollutant items, value time and concentration limits); -7 (Added validity provisions for data statistics). This standard was proposed by the Science and Technology Standards Department of the National Environmental Protection Administration. The National Environmental Protection Administration is responsible for interpreting this standard. Subject content and scope of application

Class I areas include nature reserves, scenic spots and other areas that require special protection. The second-category areas are residential areas, commercial, traffic and residential mixed areas, cultural areas, general industrial areas and rural areas determined in urban planning, while the third-category areas are specific industrial areas.
4.2 Ambient air quality standard classification
Ambient air quality standards are divided into three levels.
-Category area implements the first-level standard
The second-category area implements the second-level standard
The third-category area implements the third-level standard
