5. CHARACTERISTICS OF AIR POLLUTION
5.1. According to the data on air pollution, the concentrations of impurities are determined: one-time (20-30 min), average daily, average monthly and average annual.
5.2. Average daily concentrations are determined as the arithmetic mean of single concentrations obtained under the full program at regular intervals, including the obligatory periods of 1, 7, 13, 19 hours, and also according to continuous registration during the day.
5.3. Average monthly values of pollutant concentrations are determined as the arithmetic mean of all one-time or average daily concentrations obtained during the month.
5.4. The average annual concentration of a pollutant is defined as the arithmetic mean of one-time or average daily concentrations obtained during the year.

INTERSTATE STANDARD
Decree of the USSR State Committee for Standards of November 10, 1986 No. 3395 established the deadline for introduction
from 01.01.87
This standard applies to the rules for air quality control in residential areas of existing and newly built settlements.
The standard does not apply to the rules for air quality control in the territories of industrial enterprises.
The standard complies with ST SEV 1925-79 in terms of methods, duration and number of sampling.
1. ORGANIZATION OF CONTROL
1.1. Three categories of atmospheric pollution observation posts are established: stationary, route, mobile (under-flame).
1.2. The stationary post is designed to provide continuous recording of the content of pollutants or regular air sampling for subsequent analysis.
Stationary stations are distinguished from fixed posts, which are designed to detect long-term changes in the content of the main and most common pollutants.
1.3. The route post is designed for regular air sampling at a fixed point in the terrain during observations that are carried out using mobile equipment.
1.4. A mobile (under-flare) post is designed for sampling under a smoke (gas) torch in order to identify the zone of influence of a given source.
2. PLACEMENT AND NUMBER OF OBSERVATION POSTS
2.1. Each post, regardless of category, is located on an open area ventilated from all sides with a dust-free coating: asphalt, hard ground, lawn - in such a way that the measurement results are not distorted by the presence of green spaces, buildings, etc.
2.2. Stationary and route posts are located in places selected on the basis of a preliminary study of urban air pollution by industrial emissions, vehicle emissions, household and other sources and dispersion conditions. These posts are located in the central part of the settlement, residential areas with various types of buildings (primarily the most polluted), recreation areas, in areas adjacent to highways of heavy traffic.
2.3. The placement of stationary posts is coordinated with the local bodies of the USSR State Committee for Hydrometeorology and Environmental Control and the Sanitary and Epidemiological Service.
Support posts are not subject to transfer without prior permission from the USSR State Committee for Hydrometeorology and Environmental Control.
2.4. Sampling sites for under-flame observations are selected at different distances from a specific source of pollution, taking into account the patterns of distribution of pollutants in the atmosphere.
2.5. The number of posts and their location is determined taking into account the population, the area of the settlement and the terrain, as well as the development of industry, the network of highways with heavy traffic and their location throughout the city, the dispersal of recreation areas and resort areas.
2.6. The number of stationary posts, depending on the population, is set at least:
1 post - up to 50 thousand inhabitants, 2 posts - 100 thousand inhabitants, 2-3 posts - 100-200 thousand inhabitants, 3-5 posts - 200-500 thousand inhabitants, 5-10 posts - more than 500 thousand. residents, 10-20 posts (stationary and route) - more than 1 million residents.
2.7. In settlements, one stationary or route post is installed every 0.5-5 km, taking into account the complexity of the terrain and the presence of a significant number of pollution sources.
2.8. When conducting extended studies of the state of atmospheric pollution, the number of stationary posts may be increased in agreement with the USSR Ministry of Health and the USSR State Committee for Hydrometeorology and Environmental Control.
3. PROGRAM AND DATE OF OBSERVATIONS
3.1. Four observation programs are established at stationary posts: complete, incomplete, reduced, daily.
3.2. The full program of observations is designed to obtain information on single and average daily concentrations. Observations according to the full program are performed daily by continuous recording using automatic devices or discretely at regular intervals at least four times with mandatory selection at 1, 7, 13, 19 hours local standard time. It is allowed to conduct observations according to a rolling schedule of 7, 10, 13 hours on Tuesday, Thursday, Saturday and at 16, 19, 22 hours on Monday, Wednesday, Friday.
3.3. Observations under an incomplete program are allowed to be carried out in order to obtain information on single concentrations daily at 7, 13, 19 hours of local standard time.
Observations according to a reduced program are allowed to be carried out at air temperatures below minus 45 °С and in places where average monthly concentrations are below 1/20 of a single MPC or below the lower limit of the measurement range of impurities by the method used.
3.5. The daily sampling program is designed to obtain information on the average daily concentration. Observations under this program are carried out by continuous daily sampling.
3.6. During the period of unfavorable meteorological conditions and a significant increase in the content of pollutants, observations are made every 3 hours. At the same time, samples are taken under the torches of the main sources of pollution and in the territory of the highest population density.
3.7. Simultaneously with air sampling, the following meteorological parameters are determined: wind direction and speed, air temperature, weather conditions and the underlying surface.
3.8. At some posts, a shift of all observation periods by one hour is allowed.
It is allowed not to conduct observations on Sundays and holidays.
3.9. Monitoring of the content of dust, sulfur dioxide, carbon monoxide, nitrogen dioxide (the main pollutants) and specific substances that are typical for industrial emissions of a given settlement is carried out at the reference stationary posts.
3.10. Monitoring of specific pollutants is carried out at stationary (non-support) posts. Observations of the main pollutants at these posts are allowed to be carried out according to a reduced program () and not carried out if the average monthly concentrations of these substances during the year do not exceed 0.5 of the average daily MPC.
3.11. The list of substances for control at each stationary post in the city is established by local bodies of the USSR State Committee for Hydrometeorology and Environmental Control and the Sanitary and Epidemiological Service.
3.12. At the route posts, observations are made of the main pollutants and specific substances typical for industrial emissions of a given settlement.
3.13. At mobile (under-flare) posts, observations are made of specific pollutants characteristic of emissions from a given enterprise.
3.14. When conducting episodic surveys, observations are carried out according to a program that includes the necessary minimum of a regular program.
4. SAMPLING
4.1. The duration of sampling of pollutants in the determination of single concentrations is 20-30 minutes.
4.2. The duration of sampling of pollutants to determine the average daily concentrations for discrete observations under the full program is 20-30 minutes, for continuous sampling - 24 hours.
4.3. Sampling in determining the surface concentration of impurities in the atmosphere is carried out at a height of 1.5 to 3.5 m from the earth's surface.
4.4. Specific requirements for methods and means of sampling, necessary reagents, conditions for storage and transportation of samples, individual for each pollutant, are established in the regulatory and technical documents for methods for determining pollutants.
5. CHARACTERISTICS OF AIR POLLUTION
5.1. According to the data on air pollution, the concentrations of impurities are determined: one-time (20-30 min), average daily, average monthly and average annual.
5.2. Average daily concentrations are determined as the arithmetic mean of single concentrations obtained under the full program at regular intervals, including the obligatory periods of 1, 7, 13, 19 hours, and also according to continuous registration during the day.
5.3. Average monthly values of pollutant concentrations are determined as the arithmetic mean of all one-time or average daily concentrations obtained during the month.
