Abstract

The chemical composition and properties of soil were determined at selected sites, such as Loess plateau, Gobi and sand deserts in northern China, where most dust storms occur. Although the transport of this sort of dust storms to Korean peninsula is a well-documented phenomenon, there is not enough information about the very source regions. In this reason, this study tried to measure the chemical composition, including soil elements, anthropogenic elements and ions for soil samples so that certain properties of some major source regions of Asian Dust can be provided. Furthermore, the results are classified into four types of soil like Loess, Loess & sand, Gobi, and sand in order to identify the characteristics and difference among the types. $(X/Al)_{crust}$ values for each soil type were also calculated in this study and compared with those of other references including Asian Dust material(ADM). The results indicated that Ca contribution was higher than Al in all the soil types of this study including ADM and, compared with the values of urban area, contribution of anthropogenic elements such as Cr, Pb, Zn was quite low. However, it must be noted that there is such a variation in the result of soil composition, but it is also certain that the very source region soil composition resolved from this study could support the enhanced study on Asian Dust phenomenon in Korea.
