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.
