Studying High Ozine Levels in Bulgaria and Europe

摘要

The ozone pollution may cause damages on plants, animals and human beings when certain critical levels are exceeded. Therefore, it is important to study the actual ozone levels and the relationship between related emissions and the high levels of the ozone concentrations. Two versions of the Danish Eulerian Model (DEM) are used in this study. The fine-grid version of DEM uses grid of 480 * 480 points (10 km resolution). The coarse-grid version of DEM is defined on a 96 * 96 grid (50 km resolution). In the paper, an attempt is made as to answer the following three questions: (a) Where in Bulgaria and in Europe the highest levels of the ozone concentrations are located? (b) How big is the influence of the European emission sources on the pollution levels in the different parts of Bulgaria? (c) Is it possible to evaluate the changes of the pollution levels in Bulgaria and in Europe when the predicted for 2010 European emissions are used?
