ABSTRACT

The chemical composition and properties of soil were determined at selected sites, such asLoess 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-documentedstudy tried to measure the chemical composition, including soil elements, anthropogenicelements and ions for soil samples so that certain properties of some major source regions ofAsian Dust can be provided. Furthermore, the results are classified into four types of soil likeLoess, Loess & sand, Gobi, and sand in order to identify the characteristics and difference amongthe types. (X/Al)crustvalues for each soil type were also calculated in this study and comparedwith those of other references including Asian Dust material(ADM). The results indicated thatCa 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,composition, but it is also certain that the very source region soil composition resolved from thisstudy could support the enhanced study on Asian Dust phenomenon in Korea.
