1,National Standard of the People’s Republic of China,Ambient Air Quality Standard,(GB3095-1996),2,National Standard of the People’s Republic of China,Ambient Air Quality Standard,(GB3095-1996),1. Subject and Scope,This Standard stipulates the designation of functional areas of ambient air quality, standard classification,pollutants, sampling time and concentration limits, sampling and analyzing methods as well as the definition,of validity of data statistics.,This Standard is applicable to the evaluation of countrywide ambient air quality.,2. Reference Standard,GB/T 15262 Air Quality Determination of sulfur dioxide — Formaldehyde absorbingpararosaniline,spectrophotometry,GB 8970 Air Quality Determination of sulfur dioxide in ambient air—Tetrachloromercurate,(TCM)-pararosaniline method,GB/T 5432 Ambient Air Determination of total suspended particles — Gravimetric method,GB6921 Air Quality Determination of the concentration of airborne particulate matters,GB/T15436 Ambient Air Determination of nitrogen oxides — Saltzman method,GB/T15435 Ambient Air Determination of nitrogen dioxides — Saltzman method,GB/T15437 Ambient Air Determination of ozone — Indigo disulphonate spectrophotometry,GB/T15438 Ambient Air Determination of ozone — Ultraviolet photometric method,GB9801 Air Quality Determination of carbon monoxide — Non-dispersive infrared,spectrometry,GB8971 Air Quality Determination of Benzo[a]pyrene in flying dust — Acetylated paper,chromatography fluoroscene spectrophotometric method,GB/T15439 Ambient Air Determination of Benzo[a]pyrene in ambient air — High performance,liquid chromatography,GB/T15264 Air Quality Determination of lead—Flame atomic absorption spectrophotometric,method,GB/T15434 Ambient Air Determination of the mass concentration of fluoride — Method by,filter sampling and fluorine ion-selective electrode analysis,GB/T15433 Ambient Air Determination of the fluoride — Method by lime-paper sampling and,fluorine ion-selective electrode analysis,3. Definition,3.1 Total suspended particles (TSP): The particles that can be suspended in the air with an aerodynamic,equivalent diameter ≤ 100 micrometer.,3.2 Breathable particles (PM10): The particles that can be suspended in the air with an aerodynamic,equivalent diameter ≤ 10 micrometer.,3,3.3 Nitrogen oxide (as NO2): The nitrogen oxide existing in the air in the form of nitrogen monoxide and,nitrogen dioxide.,3.4 Lead (Pb): The lead and its compounds existing in TSP.,3.5 Benzo[a]pyrene (B[a]P): The benzo[a]pyrene existing in breathable particles.,3.6 Fluoride (as F): Inorganic fluoride existing in gaseous and particulate states.,3.7 Annual average: The arithmetic mean of daily average concentration in any year.,3.8 Quarterly average: The arithmetic mean of daily average concentration in any quarter.,3.9 Monthly average: The arithmetic mean of daily average concentration in any month.,3.10 Daily average: The average concentration on any day.,3.11 Hourly average: The average concentration in any hour.,3.12 Average in plant growth season: The arithmetic mean of monthly average concentration in any plant,growth season.,3.13 Ambient air: Outside air which human beings, plants, animals, and buildings are exposed to.,3.14 Normal state: The state at a temperature of 273K and a pressure of 101.325Kpa.,4. Grouping and Standard Classification of Functional Area of Ambient Air Quality,4.1 Grouping of functional area of ambient air quality,Group I area includes natural protection zones, scenic spots and other areas for which special protections are,necessary.,Group II area includes the residential quarters designated in town planning, mixed areas of business,communication and living, cultural areas, normal industrial areas and rural areas.,Group III area includes specialized industrial areas.,4.2 Standard classification of ambient air quality,The standard of ambient air quality is classified as three classes.,Class 1 standard is imposed for Group I area.,Class 2 standard is imposed for Group II area.,Class 3 standard is imposed for Group III area.,5. Concentration Limit,This Standard stipulates the concentration limits of various pollutants that are not allowed to be exceeded.,For the details, refer to the following table:,4,Table 1 - Concentration Limit for Various Pollutants,Pollutant Sampling time Concentration limit,Class 1,standard,Class 2,standard,Class 3,standard,Unit of concentration,Sulfur,dioxide SO2,Annual average,Daily average,Hourly average,0.02,0.05,0.15,0.06,0.15,0.50,0.10,0.25,0.70,Total,suspended,particles,TSP,Annual average,Daily average,0.08,0.12,0.20,0.30,0.30,0.50,Breathable,particles,PM10,Annual average,Dail……
