In an effort to establish databases for the heavy metal pollution in agricultural soils in the central regions of Korea, we have measured the HCl-extractable concentrations of six metals (Cd, Pb, Hg, Cu, Zn, and As) from a total of 260 surface soil samples collected during the spring seasons of l994 and l995. All of our measurements were made from three different soil groups that were divided by the surrounding environmental characteristics such as :(l) soil group -- cultivated soils within the purely agricultural regions, (2) soil group II -- both cultivated and uncultivated soils near various livelihood facilities, and (3) soil group III -- mainly cultivated soils near major pollution sources.
