Abstract

Gas phase pollutants (O,, NO* and SOj, suspended paniculate matter (SPM) and major ions in aerosols were measured for 12 month period at a mountainous site of northwestern Turkey which is suffering from severe forest decline. Gaseous pollutants, SPM and meteorological parameters were measured in hourly basis with automated analyzers. Aerosol samples were collected dafly. The long and short term trends in the concentrations of the measured parameters were investigated in order to understand the causes of the observed concentrations of these pollutants. Higher concentrations of O, during summer months were consistent with the higher photochemical production from precursor gases (NOJ w
