Information on air
pollution sources and emissions produced by different categories of
sources represents an essential input permitting an evaluation of
the contribution of each category to the overall air pollution in
the city. The REZZO 1 Category (large sources) comprises heat-generating sources whose installed capacity exceeds 5 MW, i.e. power plants, heating plants, large boiler houses, boiler rooms and certain combustion processes and technologies known to generate large amounts of pollutants, which are explicitly stipulated by the law. Falling into the REZZO 2 Category (medium sources) are heat sources the installed capacity of which ranges from 0.2 to 5 MW, as well as some processes and technologies which contribute to environmental pollution, but not as seriously as those in the first category, such as boiler units of houses and smaller blocks of flats. The REZZO 3 Category (small sources) includes all local heating units and small boilers with an installed capacity not exceeding 200 kW. The REZZO 4 Category (mobile sources) is a class unto itself, as it represents mainly the atmospheric pollution generated by automotive traffic.
The air quality assessment is based on the air quality limits for pollutants set forth in the Decree of the Federal Ministry of the Environment dated October 1, 1991, implementing Act No. 309/1991 of the Law Gazette, in the full wording of Act No. 211/94, on the protection of air against pollutants. At the moment, immission limits have been proposed for other pollutants as well. The annual air pollution assessment is primarily concerned with the relation between observed immission values and the yearly immission limit (IHr) and the daily immission limit (IHd).
Immission limits applying to air
pollutants
*
IHr / IHd / IHk - average yearly /
daily / half-hour concentration of the pollutant. Some proposed imission limits applying to the territory of the Czech Republic
Note: In the
end of 1995 and early in 1996, AIM system stations started
monitoring the content of suspended particulate matter the
aerodynamic diameter of which is less than 10 µm (PM10),
which is important from the viewpoint of its health impacts.
