Arsenic Contamination of Soils in the Vicinity of Abandoned Seongan Mine
The heavy metal concentration analysis of soils was performed to study arsenic contamination around abandoned Seongan metal mine where mine tailings is estimated approximately 42,000 m3. It is resulted that total As concentrations of top soil and tailings at the dumping site were 736± 1,223 mg/kg and 911±453 mg/kg, respectively. These values relatively higher than EU and Canadian standards for industrial region. And soluble As concentrations of those the dumping site were 387±411 mg/kg and 146±109 mg/kg, respectively, that exceeded Korean apprehension and counterplan standards. And, As contamination of soils was partially identified adjacent to the dressing plant and along the down stream from the mine, while contamination by the other heavy metals was found to be insignificant. In this specific case, recycling of the removable tailings can be considered to take advantage of its large amount, site accessibility and substantial demand for adjacent cement manufacturing factories.
