Air - Basic Information and Legislation

Air is one of the most important components of the environment; without it humans could not survive. Air is breathed at a relatively constant rate, per capita about 10 – 20 cubic metres per day.

Both natural and man-made sources discharge pollutants into the air whose presence has adverse effects on human health or the environment. The major anthropogenic sources of ambient air pollution are industrial sources, local heating and transport. Environmental protection means not only protecting ambient air against pollutants, but also clean air indoors (at work, in the home or in means of transport) free from harmful substances. Indoor air pollution can also be very dangerous to our health, because of the combination of harmful substances from ambient air and harmful substances produced by “internal sources”, such as furniture, carpets, various stoves, smoking and human activity itself.

Ambient air quality is assessed in the Czech Republic by the Czech Hydrometeorological Institute. Based on this assessment it announces areas with poor air quality, i.e. areas where one or more pollutants exceed emission limits set for them. Indoor environment quality is assessed by the Regional Health Station.
