英文摘要	Asian dust, which originates from the arid and loess regions of Central Asia, affects biological systems in remarkable ways in Northeast Asian countries. It contains a high amount of mineral dust composed of major metallic oxides, SiO2, Al2O3, CaO, and Fe2O3, which can cause adverse health effects upon high-level exposure. In the present study, Asian dust samples of spring seasons were collected for three consecutive years (2017-2019) and their elemental compositions were analyzed. A total of 42 major, minor, and trace elements were determined using two complementary analysis methods, wavelength-dispersive X-ray fluorescence spectrometry and k(0)-based instrumental neutron activation analysis. Sources of elements/dust and their contamination levels were evaluated using the data analysis tools including the HYSPLIT back-trajectory analysis, Pearson's correlation, enrichment factor, and geoaccumulation index. Although the concentrations of Earth's major crustal elements of the dust samples in spring seasons decreased appreciably for sampling events spanning 3 years, their major sources turned out to be the same, the Central Asia desert region, with negligible contaminations from the other sources. It was further supported by the back-trajectory analysis and the characteristic calcite compositions of different desert soils. This study successfully demonstrated the performances of combined data analysis tools for source identification, providing results with excellent consistency.
