WHEN IS AIR POLLUTION MONITORING NECESSARY?
Air pollution monitoring is a systematic observation of the quality of atmospheric air.
Atmospheric air is a vital component of the environment, an integral part of the human environment, plants and animals - this definition gives the Federal Law of 04.05.1999 N 96-FZ "On the protection of atmospheric air."
State monitoring of air pollution is carried out in accordance with the Federal Law "On the Protection of Atmospheric Air" in order to "monitor air pollution, comprehensive assessment and forecast of its condition, as well as to ensure state authorities, local governments, organizations and the population current and emergency information on air pollution. "
In accordance with the law, "citizens, legal entities and public associations have the right to information about the state of atmospheric air, its pollution, as well as about the sources of air pollution and harmful physical effects on it." In practice, this information is communicated to the public only in the form of summarized analytical reports published annually by the hydrometeorological service, or in emergency situations.
Therefore, if you are going to purchase land in an environmentally friendly area and move "closer to nature", you are unlikely to find information in open sources about the level of pollution of the atmosphere, water, soil, despite the fact that the environmental information cannot to be classified. Air analysis at the boundaries of the sanitary protection zone of enterprises, carried out in order to establish its boundaries, also relates to the activity on determining the level of air pollution and requires, in accordance with the explanations of the Ministry of Environment, a license in hydrometeorology and related areas.
EQUIPMENT AND METHODS OF STUDIES OF ATMOSPHERIC AIR
The physico-chemical laboratory has a wide range of measuring instruments and methods for monitoring air pollution:
Measuring complex SCAT. The gas analyzers included in the complex make it possible to measure the concentrations of ozone (O3), carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NO, NO2), ammonia (NH3), hydrogen sulfide (H2S) and sulfur dioxide (SO2).
TSI DustTrak 8533 dust analyzer. The dust analyzer integrates with the automated complex SCAT and allows measuring the concentrations of dust and suspended particles PM10 and PM2.5 in atmospheric air by an optical method in real time.
Weather station AIIS VP-22 - for registration of meteorological parameters - temperature, humidity, atmospheric pressure, wind speed and direction, rainfall intensity. The weather station is also integrated with the SCAT measuring complex.
Gas chromatographic methods of analysis allow for sampling and analysis of air for the content of volatile organic compounds.
High performance liquid chromatography methods are used to measure concentrations of benzopyrene in ambient air.
A wide range of photometric methods with sampling in absorption solutions for the analysis of atmospheric air for mercaptans, formaldehyde and other substances has been introduced into the laboratory.
To determine the mercury vapor, a RA-915M mercury analyzer is used.
Gravimetric methods are also used in the laboratory - for example, to determine the content of dust and soot in ambient air.
