    Chemical Analysis of Wet Deposition Sequential Samples at Istanbul, Turkey
    (Kırıkkale Üniversitesi, 2017) Oruc, İlker; Akkoyunlu, Bulent Oktay; Dogruel, Murat; Tayanc, Mete
    Inthis study, the relations between wet deposition fluxes of major ions,concentrations and rain intensity in the precipitation events occurring on a)November 10th, 2007 and b) December 05th, 2007 arepresented. The variations on the ion concentrations were investigated duringthe rain events. The concentrations of all ions drastically decreased tominimum levels in the first sub sequential events for each the rain events.Some ions had a significant decrease in concentrations in comparison with otherions, because they have higher concentration in the atmosphere as much as theyexist in the large atmospheric particles which are being sourced from in thesoil or sea. The strongest relation between the wet deposition flux and therain intensity were found for Ca2+ and SO42-among the all the ions sampled on November 10th, 2007. It was foundthat K+ and NO3- concentrations sampled onDecember 05th, 2007 had a positive correlation with rain intensity;on the other hand, other ions had a negative correlation. Positive correlationswere found between wet deposition flux and the rain intensity for all ions ineach rain events.

    Ion Concentrations And Sources Of Sequential Sampling Of Wet Deposition In Istanbul, Turkey
    (Kırıkkale Üniversitesi, 2017) Oruç, İlker; Akkoyunlu, Bulent Oktay; Dogruel, Murat; Tayanc, Mete
    This study presents the relationships betweenion concentrations and sources of ions in the precipitation events whichhappened on a) September the 08th, 2007 b) November the 10th, 2007 and c)December the 05th, 2007. Fortyfour sequential rain samples were collected inthree rain events that were sampled in Istanbul-Turkey making use of asequential rain sampler. Concentration of the main cations (K+, Ca2+, Na+, andMg2+) and main anions (Cl-, SO42-, and NO3-) were analyzed. The ratio of themean and nbsp;Ca2+ and nbsp;(0.85) and nbsp;non-sea salt and nbsp;concentration to the meantotal concentration and nbsp;led to the conclusion that most of the Ca2+ came fromsoil. This ratio for SO42- ranged between 0.49 and 0.98, indicates a possibleconclusion that the domestic heating and industrial activities were the mainsource of this ion.
