영문 초록

Minari(Oenanthe stolonifera DC.) lived in serious polluted water is able to remove chemical elements from batch system. This study attempted to compare the incorporation of cadmium and lead in batch system. Different concentrations of Cd(0.02 0.1 0.5 1.00 5.00 mg/l) and Pb(0.1 0.5 1.0 5.0 10.0 mg/l) were used. Toxic effects were obvious at Cd 1.00 mg/l and Pb 5.00 mg/l. The detrimental effects on minari were chlorosis of leaves and stunted roots and reduction in the number of lateral roots. There was reduction in growth rates exposed above Cd 1.00 mg/l and lead 5.0 mg/l. The minari capacities to remove Cd were 34.1-74.2% and Pb were 53.0~91.5%. The removal rates by minari in Cd and Pb solution were decreased with increased exposure concentration(in Cd r=0.97, in Pb r=0.88). The removal rates by minari in Cd and Pb solution were increased with increased growth rate(in Cd r=0.93 in Pb r=0.92). Recovery rates on minari are 67.3~95.2% in Cd water and 72.6~88.3% in Pb water. The rates are increased with increased growth rates and decreased initial concentrations.
