| Outline of Final Research Achievements |
Absorption behavior of zinc and cadmium was elucidated using hydroponic cultivation system of Arabidopsis halleri ssp. gemmifera (Jananese name: HAKUSANHATAZAO) which is a hyperaccumulating plant of zinc and cadmium in this research. Experimental results showed that cadmium is absorbed without an influence of zinc concentration. From the results
Water quality of artificial and actual mine drainage were proved to be improved by this hydroponic system. Basic design of a cadmium containing mine drainge treatment plant showed that this system is applicable in to apply actual mine drainge containing cadmium.
