The aim of this work is to study precipitation chemistry in the cross-border region between Turkey and Bulgaria, situated on the south-eastern part of the Balkan Peninsula. A total of 115 wet deposition samples were collected and analysed for pH values and major ions (Na⁺, Mg²⁺, Ca²⁺, K⁺, NH₄⁺, Cl⁻, NO₃⁻, and SO₄²⁻) throughout the summer and autumn seasons of 2014. The enrichment factor analysis and non-sea salt estimates were conducted to determine the possible sources of ions in the wet deposition for the sampling period. The trajectories of the cyclones affecting the area during the study period were also analysed by separating them in different groups. The minimum, average and maximum pH values for the first group of cyclones (CG1) are 4.30, 6.04, 7.40, and 4.00, 6.14, 7.43 for the second group cyclones (CG2), respectively. The non-sea salt fractions of the K⁺ ion were found to be 0.94 in CG1 and 0.90 in CG2. Also, the Mg²⁺ ion in CG1 and CG2 is 44% and 60% of the sea salt source.

这项工作的目的是研究位于巴尔干半岛东南部的土耳其和保加利亚之间的跨境地区的降水化学。共有115个湿沉积收集样品并用于pH值和主要离子（Na分析⁺，镁²⁺，钙²⁺，K ⁺，NH ₄ ⁺，氯^-，NO ₃ ^-和SO ₄ ^2-）在2014年夏季和秋季的整个季节。进行了富集因子分析和非海盐估算，以确定采样期间湿沉降中离子的可能来源。还通过将旋风分离成不同的组来分析研究期间影响该地区的旋风的轨迹。第一组旋风器（CG1）的最小，平均和最大pH值分别为第二组旋风器（CG2）的4.30、6.04、7.40和4.00、6.14、7.43。发现K ⁺离子的非海盐分数在CG1中为0.94，在CG2中为0.90。此外，CG1和CG2中的Mg ²⁺离子分别占海盐源的44％和60％。
