Abstract

Concentrations of SO% and NO^ species over the Sudeten, Poland, during several field campaigns over a period of 1988-1993 J.W. Zwozdziak, A.B. Zwozdziak Institute of Environment Protection Engineering, Wroclaw Technical University, 50-370 Wroclaw, Poland ABSTRACT The results of several separately performed fields studies on air quality in south- western Poland are presented. Under typical westerly wind conditions, this area is exposed to a heavily polluted air masses originating mainly in Central Europe. The results prove that even within the same air trajectory highly variable pollutant concentrations, particularly secondary aerosols, were monitored Then- highest concentrations corresponded with ascending boundary layer air before the cold front. Some selected air quality parameters and meteorological factors have been subjected to the numeric-symbolic analysis and the results are discussed.
