초록
This study has focused on investigation on As and heavy metal contamination derived from metalliferous mining activities in the Choongbuk Province in Korea. Soil, mine effluent, surface water and ground water samples were taken in and around 27 abandoned metal mines, and analyzed for As, Cd, Cu, Ni, Pb and Zn using AAS and anions in water samples using IC. In general, the heavy metal concentrations in soils decreased with Increasing distance from the each mine audit. Tailings and mine waste soils from several mines contained over the guideline of Soil Conservation Act in Korea. Soil samples from the Seobo, Honga, Daehwa, Jeungjadong, Youngbo and Munbaek mines contained over the action levels of the metals due to intensive mining activities. Therefore, a proper remediation work needs to control the metal dispersion around the mines.
