Özet

Seasonal variations in the chemical characteristics of wet and bulk deposition samples collected in Erzurum were investigted for the period March 2002-January 2003. Major cations (Ca2+ K+ Mg2+) and major anions (SO42- NO3-) were determined in bulk and wet deposition samples; pH was also measured in wet deposition. The average PH of the wet deposition at Erzurum was 6.6 due to extensive neutralization of the acidity. A strong relationship between PH and SO42- concentrations was observed in all seasons; however, only a weak relationship was found between PH and NO3-. On a seasonal basis, the correlation between Ca2+ and SO42- concentrations was stronger in winter than in summer.
