Alkali and Metal Element concentrations in Soil and Plant from Daesung Coal Mine in Keumsan, Chungnam

the research has been made for alkali and metal element concentrations in top soils and plants from the abandoned coal mine, Keumsan, Chungnam Province. Samples of the top soil and plant (Miscanthus sinensis and Pinus rigida) were collected from the mine area in which was divided into t재 regions the polluted region influenced by the coal mining and the non-polluted region. pH of the top soils was 3.16-4.33 in the polluted region. Ca, Sr and P concentrations were high in the polluted soils, and Al and Ba concentrations were high in the non-polluted soils. No differences were found in K, Na and Ti concentrations. M. sinensis was higher in the element concentrations than P. rigida. In the average concentration of the alkali and metal element, M. sinensis showed high Cs and Na in the polluted region, and high Ba, Ca, K, Sr and concentrations in the non-polluted region. P. rigida had high Cs, Na and Rb concentrations in the polluted region. M. sinensis and P. rigida were higher in the root than above-ground part in the most element, but Ca and K. Ca, K and Na concentrations within both plants had higher than those of soils.
