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 25...

The preliminary goal of this study is to design, construct and test an automatic sequential precipitation sampling instrument. Testing includes collection of sequential precipitation samples, analyzing them and trying to find the sources of environmental pollution. Proposed sequential sub-event sampler is composed of two parts; mechanic and electronic hardware. Mechanical part includes a stepped 100 ml sampler cups on it, and a metallic body. Electronic part is composed of digital and analog sensors, various elect...
