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.eninfo:eu-repo/semantics/openAccessAerosol sourcessequential samplingwet depositionArticle92-13113610.29137/umagd.352522352522
