Abstract

Close to city forests have distinct recreational purposes, according to air pollu- tion conditions. There are influenced by internal and external factors. The differ- ences in air pollution structure between two cities and two forests which are close to the cities in Southwest Germany were investigated. The results are based on data supplied by official stations for the monitoring of air quality, in this case for the pollutants NO, NO] and O, in the period 1992 through 1996. The results for both weekdays and weekends, presented as average diurnal cycles of the analysed air pollutants, reveal that concentrations of NO and NO] were much higher in urban areas. Levels of concentration of Og, however, were higher in the close to city forests. The differences in air quality depend on the specific location of
