在 INTERREG IT-HR 项目 ECOMOBILITY 的实施过程中，其目标之一是估算船舶排放对港口城市里耶卡（克罗地亚）和威尼斯（意大利）空气质量的影响，每周收集了两个样本Rijeka，在采样的第一周和第十三周，即分别为 S01（2018 年 10 月 16 日-23 月 23 日）和 S13（2019 年 4 月 24 日-30 月 30 日）。两个样本在沙漠尘埃贡献的物种特征方面具有相似之处，但 HYSPLIT 分析排除了撒哈拉沙漠作为 S01 样本的来源。与撒哈拉沙尘不同，该样品含有大量细颗粒和超细颗粒（分别为 >50% 和 9.8%），以及次生无机（硫酸盐、铵）和有机（水溶性有机化合物 - WSOC）气溶胶。详细的天气情况和 HYSPLIT 向后轨迹指出叙利亚沙漠是该收集样本的来源。 MERRA-2 对沙漠沙尘排放的再分析也证明了同样的来源。尽管撒哈拉沙尘事件（主要是降水）在北亚得里亚海地区众所周知，但这是第一次表明叙利亚沙漠是空气颗粒物的来源。这一假设得到了叙利亚沙漠化学物质特征的证实，即来自钾长石和磷酸盐的钾含量较高。

Airborne desert dust in the Northern Adriatic area (Croatia): Different sources

During the implementation of the INTERREG IT-HR project ECOMOBILITY, whose one of the goals was to estimate the impact of ship emissions on air quality in the port city of Rijeka (Croatia) and Venice (Italy), two particular weekly samples were collected in Rijeka, during the first and the thirteen weeks of sampling, i.e. S01 (16.10.-23.10.2018) and S13 (24.04.-30.04.2019.), respectively. Both samples have similarities regarding species characteristic for desert dust contribution, but HYSPLIT analyses excluded Saharan desert to be the source of the S01 sample. Unlike Saharan dust, this sample had a high contribution of fine and ultrafine particles (>50 % and 9.8 %, respectively), as well as secondary inorganic (sulfates, ammonium) and organic (water soluble organic compounds - WSOC) aerosols. Detailed synoptic situation and HYSPLIT backward trajectories pointed out the Syrian Desert as the source of this collected sample. The same source was proved by MERRA-2 reanalysis of the desert dust emission. Although the Saharan dust episodes, mostly in precipitation, are well known in the Northern Adriatic area, this is the first time to indicate Syrian Desert as a source of airborne particulates. This assumption was confirmed with chemical species characteristic for the Syrian Desert, i.e. higher content of potassium from K- feldspar and phosphates.
