  • In this research we determined the levels of heavy metals in soil and metal-accumulating plants from a D military shooting site in the Kyungkido district of Korea. The data obtained may be useful in the development of methods for the efficient phytoremediation of contaminated soil. The total Cd, Cu, Pb, and Zn concentrations in the soil were found to be 1.67-5.04 mg/kg, 52.51-106.26 mg/kg, 37.24-90.32mg/kg, and 111.45-188.19mg/kg, respectively. These results show that the soil is contaminated with Cd and Cu, and this contamination is particularly severe in the case of Cd because of its high bioavailability (25-57% of the total metal in the soil is exchangeable). The high concentrations of heavy metals in the shoots of Persicaria thunbergii and Artemisia princeps var. orientalis indicate that these plants (all perennial herbs) accumulate heavy metal efficiently. Further, these plants were found to contain more Cd in its shoots (>60% of the total metal found in the plant) than any other plant; these results indicate that these native species are particularly suited to use in Cd phytoextraction.

  • Physical, chemical and biological properties of soils and cadmium(Cd) content of Artemisia princeps var. orientalis collected from 10 metalliferous mines were analysed. Cd contents of unplanted soils and rhizosphere soils were not significantly different(p < 0.05), and mean values were 5.92 and 5.91 mg/kg, respectively. In addition, Cd content of rhizosphere soils were correlated with Cd content of Artemisia princeps (p < 0.05, ${R^2}_{shoot}$ = 0.3120, ${R^2}_{root}$ = 0.4177). Minimum data set(MDS) of soil quality parameters for statistical assessment of Cd uptake was established by principal component analysis, and it was identified as organic matter(OM), dehydrogenase activity(DHA), pH, exchangeable Mg. According to multiple regression analysis using the MDS, coefficients of determination ($R^2$) for Cd uptake of shoot and root of Artemisia princeps were found to be 0.3418 and 0.5121, respectively. This suggests that statistical soil quality assessment using the MDS seems a useful tool to interpret heavy metal uptake of plant.

  • This study was carried out to select proper species for early stage replantation in granite forest roads cut-slope. From two to sixteen year elapsed forest roads in four regional areas of Gangwon-do, sample plots were selected, and their vegetations and environmental factors were investigated. Soil organic matter, total nitrogen, soil moisture content, and bulk density in the decomposed granite soils were below 1.32%, 0.08%, 10.0%, and above 1.24g/$cm^3$, respectively. The result indicated that the soil was not good for plant growth. The environmental factors affecting distribution of species in the granite forest roads were the elapsed year, cut-slope, elevation, and cut-slope aspect. Species with high frequency in the granite forest road cut-slope ordered Lespedeza bicolor, Rubus crataegifolius, Pinus densiflora, Lysimachia clethroides, Amorpha fruticosa, Dactylis glomerata, Lespedeza cyrtobotrya, Festuca arundinacea, Spodiopogon sibiricus, Artemisia stolonifera, and Weigela subsessilis.

  • This study was performed to investigate the effects of dried leaf powders and ethanol extracts of Perilla frutescens(perilla leaf), Artemisia princeps var. orientalis(mugwort) and Aster scaber(chamchui) on lipid metabolism and antioxidative capacity in rats. Forty-nine male Sprague-Dawley rats weighing 105.9$\pm$1.7g were blocked into seven groups according to body weigth and raised for four weeks with diets containing 5% dried powders of perilla leaf, mugwort and chamchui, or ethanol extracts from the same amount of each dried leaf powder. Food intake was higher in the control and chamchui powder groups than the other remaining groups. Weight gain was not significantly different among all experimental groups. Food efficiency ratio was highest in the perilla leaf powder group. Plasma total lipid and cholesterol, liver total lipid and triglyceride levels were highest in the perilla leaf powder group. In contrast, dried powders of mugwort and chamchui showed hypolipidemic effects in plasma and liver. Plasma and liver TBARS levels in both dried powder and ethanol extract groups of the three plants were lower than control. There was also no significant difference between corresponding dried powder and ethanol extract groups. Catalas and GSH-Px activities in erythrocyte and liver were not different among all the experimental groups. However, SOD activities were significantly different among the esperimental groups. In erythrocyte. SOD activiteis of all dried powder and ethanol extract groups except the perilla leaf powder group were higher than control, and the chamchui power group showed the highest activity among them. In liver, all the plant groups showed higher SOD activities than control. There was no significant difference between corresponding dried powder and ethanol extract groups. In conclusion, the dried chamchui powder and liver. All the dried plant powder and ethanol extract were effective in decreasing the TBARS levels of liver and particularly plasma. Among the antiocidative enzymes, SOD activity was most responsive to the experimental diets. All the plant groups showed increases in liver SOD activities and there were more increments in dried powder groups. Since the effects of dried powder groups on lipid metabolism were better than those of extract groups, it is plausible that the high dietary fiber level in dried powders was effective. Antioxidative effects were not significantly different between corresponding dried power and extract groups, and it was thought that ethanol extracts from three plants also had similar antioxidative effects as dried powderers.
