Air Quality

The term exterior air quality describes the level of exterior air pollution, which may affect human health, vegetation, entire ecosystems and materials. Exterior air pollution is caused by the emission of pollutants from various sources as a consequence of human activity (such as transportation, combustion, industrial production, etc.). Pollutants emitted from a source are transported in the atmosphere and can thus affect the air quality in both the immediate vicinity of the pollution source and the broader territory.

The fundamental legal regulation covering air quality assessment and management is Act no. 86/2002 Coll., on air protection, as amended. Further details are specified by Government Regulation no. 597/2006 Coll. on the monitoring and evaluation of air quality (hereinafter, the Regulation). The Regulation sets out the permissible levels of air pollution (pollution limits, target pollution limits, and long-term pollution targets) for a total of thirteen pollutants with established negative effects on human health, ecosystems, and vegetation.

Summary information on air quality in the past year is presented to the Government Assembly on an annual basis; it is also published on the Ministry of the Environment website. Information on air quality for the past years is also available on the Czech Hydrometeorological Institute website.
