| Research Abstract |
In this research, we developed Geo-database systems to store geological/geotechnical and geochemical information and to evaluate distribution of naturally contaminated soils and sediments by heavy metals over a wide area. The availabilities of soil and sediment samples which were taken through the standard penetration test were performed in the perspectives of applications in environmental science. Results revealed that the total content of arsenic is applicable adequately even for the old and oxidized samples such as the SPT samples. As an application of database, a method for differentiating naturally polluted soil and anthropogenically one were proposed. Portions of data stored in databases were released over the Internet.
