Abstract

The influence of washout scavenging on the removal processes of SO 4 2-, NO3 - and Cl - ions were investigated using sequential ra in sampling. For this purpose this study investigates the variation of these ions in precipitation using the sequential rain sampling and relationships of the wet depos ition flux to the rain intensity and ion concentration were introduced. We carried out sequential rain sampling for five different rain events sampled in Istanbul on a) March 14 th, 2008 b) March 20 th, 2008 c) March 25th, 2008 d) April 6th, 2008 and e) May 4th, 2008. The correlation coefficient between SO 4 2- and NO 3 - which have main source domestic heating and industrial activities was calculated as 0.80, however inverse relation between NO3 - and Cl- which have different sources was found. The correlation between these ions was calculated as -0.60. Correlation coefficients between ra in intensity and wet deposition flux for SO 4 2-, NO3 - and Cl- calculated as 0.99, 0.94, 0.95 respectively. On the other hand weak relation was found between wet deposition flux and ion correlations. These results indicated that rain intensity has more dom inant mechanism for wet deposition compression to the ion concentrations.
