In order to investigate the content of heavy metals in soil according to vertical profiles, 72 soil samples were collected from 4 sampling sites: Ulchiro-2 ga, Dugdo, Sungnaedong, and Amsa-dong. The content of mercury was measured by a mercury analyzer and those of lead, copper and zinc were measured by an atomic absorption spectrophotometry. From the results of this study, it was shown that the content of heavy metals decreased gradually from the surface soil to the 2m-depth soil But, there was no difference in the contents of the heavy metals in the 3m, the 4 m and the 5m-depth soil.
