摘要

Hungarian air pollution levels are studied by using the Danish Eulerian Model. The air pollution levels under consideration include (i) concentrations of SO₂, NO₂, NH₃ and O₃ and (ii) four quantities related to critical ozone levels (accumulated exposure over threshold of 40ppb values for crops and forests, the number of days when 8-h rolling averages of ozone concentrations exceed 60ppb, and averaged over a given period daily maxima of the ozone concentrations). Setting all the Hungarian emissions to zero, we estimate the contributions from the SO₂, NO_x, VOC and NH₃ emissions in the other European countries to the Hungarian pollution levels. An attempt to evaluate the Hungarian pollution levels for year 2010 is made under the assumption that the European emissions will, in general, be reduced considerably before year 2010.
