抽象。2000年7月和2001年1月，在希腊克里特岛东北海岸的Finokalia，使用一个Berner低压撞击器收集了尺寸分离的气溶胶样品。在夏季活动期间，还在爱琴海的“AEGAIEO”号研究船上采集了几个样本。重量分析和反演技术得出每日PM1和PM10质量浓度。样品还进行了PIXE分析，给出Al，Si，K，Ca，Ti，Mn，Fe，Sr，S，Cl，Ni，V，Cu，Cr，Zn和Pb的元素粒度分布。地壳元素和海盐具有单峰的超微米粒度分布。硫主要存在于亚微米级分中。K，V，和Ni表现出双峰分布与森林火灾和石油燃烧产生的亚微米模式。人为因素的分布范围很广，但并不明确。PM1和PM10质量浓度和元素浓度的时间序列表现出每日和季节变化。较高的质量浓度，观察到在两次入侵的撒哈拉沙漠的灰尘，而较高浓度的S，铜，锌，铅，在空气质量到达从希腊北方或土耳其西海岸收集的样本中遇到。在一些样本中发现了高浓度的氯，这些样本中的空气团要么来自大西洋上空，然后通过西欧到达菲诺卡利亚，要么在黑海西海岸上空再循环。
Abstract. A Berner low pressure impactor was used to collect size-segregated aerosol samples at Finokalia, located on the north-eastern coast of Crete, Greece during July 2000 and January 2001. Several samples were also collected during the summer campaign aboard the research vessel "AEGAIEO" in the Aegean Sea. Gravimetric analysis and inversion techniques yielded daily PM1 and PM10 mass concentrations. The samples were also analysed by PIXE giving the elemental size distributions of Al, Si, K, Ca, Ti, Mn, Fe, Sr, S, Cl, Ni, V, Cu, Cr, Zn, and Pb. The crustal elements and sea-salt had a unimodal supermicron size distribution. Sulphur was found predominantly in submicron fractions. K, V, and Ni exhibited a bimodal distribution with a submicron mode produced by forest fires and oil combustion. The anthropogenic elements had broad and not well-defined distributions. The time series for PM1 and PM10 mass and elemental concentrations showed both daily and seasonal variation. Higher mass concentrations were observed during two incursions of Saharan dust, whilst higher concentrations of S, Cu, Zn, and Pb were encountered in samples collected in air masses arriving from northern Greece or the western coast of Turkey. Elevated concentrations of chlorine were found in samples with air masses either originating above the Atlantic Ocean and arriving at Finokalia via western Europe or recirculating over the western coast of the Black Sea.
