质子激发X荧光法测定西太平洋海域雨水的微量元素组成

Determination of trace elements in marine rain water over the western Pacific Ocean by PIXE

用质子激发Ｘ荧光分析法测定了西太平洋海域海面上雨水中微量元素的组成和浓度，并通过富集因子的计算，表明海面上雨水中的地壳元素和污染元素主要来自陆地长距离输送的尘土粒子及人为排放污染物。

Proton-induced X-ray emission (PIXE) technique was used to measure concentration of trace elements in marine rain water over the western Pacific Ocean.The calculation of enrichment factors of various elements indicated that crustal and pollutant elements came mainly from long distance transportation of soil-dust particles and anthropogenic pollutant, respectively.
