A total of 128 samples were analyzed for sixteen elements including Al, Ca, Ce, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, Sr, Ti and V with ICP atomic emission spectrometry and atomic absorption spectrometry. Areal distributions and cumulative frequency distributions of the elements were discussed in view of sources for the elements. Samples from the area where granitic rocks are exposed are rich in Al, Ca, Na and Sr. On the contrary, Co, Cr, Fe, Ni and V are enriched in samples from the area underlain by Tertiary sediments. The distributions of these nine elements are considered to be closely related to the exposed rocks. Concentrations of Cu, Fe, Mn, Ni, and P are high in samples from some places without any correlation to the geology. Natural backgrounds of the elements seem to be overlaid with the elemental dispersion due to human activities. Drainages from human activities and many china-ware factories in and around Seto City are the main sources for some elements such as Cu and P.Correlation coefficients higher than 0.7 are observed between abundances of Ti-Ce, Fe-Mn, Ti-V, Ce-V, Ca-Sr, Na-Ca, Na-Al and Fe-V. The Ti-Ce correlation is found to have originated from sphene, a Ti-bearing mineral. The Fe-Mn-V correlation is considered to have come from iron oxides and Fe-Mn deposit in river bottoms. The correlation among Ca-Sr-Na may reflect compositional variations in a rock-forming mineral, plagioclase. A clear distinction of a dispersed element by human activities in the natural background is the fundamentals for environmental assessment. The geochemical map is found to be a potentially important tool to clarify various sources of elements distributed in the geosphere.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"国立情報学研究所で電子化したコンテンツを使用している。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/2818"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/joueps.41.1","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Dept.
