Atmospheric Air Monitoring

Automatic atmospheric air control station. Minsk

The main purpose of the atmospheric air monitoring is to carry out regular observations of atmospheric air conditions and to make an assessment, forecast and identification of the trends in its deterioration in order to prevent negative situations threatening public and environmental health.

The existing stationary network operating under the methodical guidance of the Republican center for hydrometeorology, radiation control and environmental monitoring was formed in accordance with regulatory and legal documents, as well as the Engineering Design of the National System of Environmental Monitoring in the Republic of Belarus. Atmospheric air is monitored in 15 cities at
54 stations. The air is sampled 3-4 times a day (except weekends and National holidays).

The concentration of the atmospheric air pollutants in the cities of Belarus

About 318 thousand samples of the ambient air are taken annually in the Republic, which are analyzed for 37 pollutants.

The study of the chemical composition of atmospheric precipitation is a major component of the atmospheric air monitoring. Presently, the acidity, components of the basic salt content and heavy metals are regularly controlled in the precipitation at 16 points in the Republic.

Dedicated transboundary station Vysokoye at the western Belarusian border is designed to study the atmospheric long-distance migration of pollutants. The study of the atmospheric air and precipitation within the frames of the Global Atmosphere Service of the World Meteorological Organization has been conducted for more than 20 years at the complex background monitoring station “Berezinsky Biosphere Reserve”. Concentrations of main pollutants, ozone surface layer and fine particles with the size of less than 10 μm are measured in the atmospheric air. Observation data are regularly provided to international organizations. Snow-survey method is used to assess the anthropogenic load on natural media via aerial fallings including the transboundary migration.

Aiming to prevent higher air pollution during the periods of unfavorable meteorological conditions 80 major industries and motor transport enterprises in 10 cities of the Republic are informed about the expected higher level of the air pollution. The total exceeding 300 alerts and notifications are made annually. The efficiency of the work performed is obvious: in 70% cities where these activities take place the atmosphere pollution index reduced or stayed unchanged.

Atmospheric air pollution data are processed by the automated system «Pavetra» developed at the Republican center for hydrometeorology, radiation control and environmental monitoring. «Pavetra» also provides for a reliable storage of unique multiyear information and high level of work with archived data. «Pavetra» operation results in monthly memoranda, quarterly and semiannual overviews, year-books on the condition of the atmospheric air in the cities and industrial centers of the Republic of Belarus, information for the collections of the Republican center for hydrometeorology, radiation control and environmental monitoring, chapters of the environmental bulletin «Environmental Conditions in Belarus», statistical collection «Environment and Natural Resources of the Republic of Belarus», and information about the air conditions and background concentrations.


The consumers of the information about the atmospheric air pollution are: Ministry of Emergency Situations, Ministry of Health, Ministry of Statistics, Ministry of Economy, National Academy of Science of Belarus, State Traffic Police of the Directorate of Internal Affairs, executive and administrative authorities, Prosecutor’s Office and mass media.

The results of observations over the atmospheric air pollution are widely used when preparing long-term plans for the development of the country’s economy, for the rational placement of residential houses and industries, in governmental planning of the atmospheric air protection activities, and for the study of the air pollution impact on public health.
