Abstract: | The gradual increase in temperature is one of the most pronounced trends of climatic changes in the atmosphere. The pollution levels depend essentially on the emissions (both on the human-made emissions and on the biogenic emissions) as well as on the chemical reactions which take place during the transport of pollutants in the atmosphere. Since both the chemical reactions and the biogenic emissions depend on the temperature, it is obvious that the gradual increase of the temperature will have some effect on pollution levels. The impact of climatic changes on high ozone levels, which may have damaging effects on human health, is studied in this paper. Eight European suburban areas were selected. These areas are densely populated and, therefore, increased ozone pollution levels may cause harm to a great number of human beings living there. All experiments indicate that, although the changes of the ozone concentrations are relatively small, some critical levels, which are related to ozone concentrations and which may have damaging effects, will be significantly exceeded as a result of the warming trend in the future climate. |
