Dissolution properties for the 6 inorganic pollutants (As, Cd, Cu, Pb, Zn, Cr) in soils have been studied. These 6 inorganic pollutants were spiked to 3 kinds of fresh soils which were sand, clay, and loam. The dissolution properties of the prepared samples were investigated under the various extracting conditions such as extracting time, acid concentration, particle size, etc. in order to obtain basic information about the process of extraction test and improvement of related analytical methods. As the results, dissolution properties were affected mainly by acid concentration in extracting procedure and mineral composition of soils. On the other hand, extracting time, sort of acids and particle size of soils had a little influence on the dissolution properties. Cd revealed very high dissolving efficiency and As was very low in whole extracting test.
