<p>Ambient air quality in the present-day Czech Republic (CR) one of the two succession</p><p>countries of Czechoslovakia post-1993 was perceived as a major problem with severe</p><p>human health and environmental consequences particularly between the 1970s and</p><p>1990s. Since that time the ambient air quality in the CR has improved substantially due</p><p>to newly introduced stringent legislation and technical countermeasures. Nevertheless</p><p>there are still activities which represent significant emission sources such as local</p><p>heating and increased vehicle travel through communities. Aer a substantial decrease</p><p>in emissions in both the CR and its neighbouring countries the levels of some ambient</p><p>air pollutants from the 2000s are still not satisfactory. In this respect aerosol groundlevel</p><p>ozone and benzo[a]pyrene remain major problems as they do elsewhere in</p><p>Europe. The book provides a valuable update both on time trends and spatial changes in</p><p>ambient air quality and highlights the recent activities in both monitoring and modelling</p><p>of principle ambient air pollutants in the CR.</p>
