Concentrations of the selected air pollutants at Bily Kriz, the Czech Republic, for 1994 to 1999

Air pollution related problems, such as acidification, air quality and ground-level ozone, are recognized as some of the important problems facing the people of the Czech Republic, whose health is damaged by impacts of air pollutants. Also the impacts of these air pollutants on human health, forests and vegetation are investigated. This paper presents evaluation of air pollution caused by sulfur dioxide, nitrogen oxides, particulate matter and ozone, based on the readings of measuring site at Bílý Køíž for the six-year period 1994-1999. The evaluation of the status of the ambient air pollution is based on air pollution limit values as specified by the new European Directives. Concern has been expressed about the possible effects of ozone, nitrogen oxides, sulfur dioxide and particulate matter exposures on forested areas, materials and human health. The main objective of this study is to examine the evolution observed in the concentrations of these air pollutants considered. The reduction is observed for winter air pollutants as sulfur dioxide and particulate matter from 1996 to 1999. In contrary, the ozone concentrations increase considerably for the same period.
