| Outline of Final Research Achievements |
In order to propose an effective and efficient way of purifying contaminated ground, “eco-friendly simulator on phytoremediation” was developed. It can analyze effect of purification with time. Two-dimensional analytical field was assembled, and to inspect accuracy of the developed simulator, some cultural experiments were conducted with several concentrations of hexavalent chromium (Cr6+) on “Two-dimensional nursery apparatus”. Turnip leaf and sunflower were tried for the cultural experiment.Following outcomes were obtained from this study.
1) The most effective growth parameter of plants for phytoremediation was elongation speed of root. 2) An accurate simulator could be developed which corresponds to experimental results for 1 month.
