計畫中文摘要	近來高雄市區大坪頂特定區(10 公頃)、屏東縣萬丹鄉大鼎飼料(0.58 公頃)及 新園鄉赤山巖(4.77 公頃)等土壤污染場址，因面積廣闊、污染深度及污染濃度等問 題，若以國內常用之翻轉稀釋、土壤酸洗及排土客土等技術估算所需經費將為龐 大數字。針對此些場址以風險為考量之綠色整治技術(Green remediation)，為未來 可行之策略。其包括太陽能板、風力發電等設置及生物能源，如向日葵等植生萃 取(Phytoextraction)，在有效之必要風險評估後之阻絕及監測規劃，應可取代目前 常用之土壤整治技術。本計畫將對能源作物向日葵進行土壤重金屬之改善研析。 探討整合過氧化鈣、植物生長激素與螯合劑植生復育受重金屬污染土壤，並進一 步評估能源作物向日葵復育受重金屬污染土壤操作方式暨相關環境因子擬定。並 藉由實驗探討過氧化鈣、植物生長激素與重金屬對植體生長情形(植體形態分析) 暨重金屬累積傳輸效益之影響。另以生物可分解性螯合劑添加改變土壤重金屬生 物有效性，配合植物生長激素提昇植體生長，探討植體植體重金屬累積傳輸情形。 此外，亦以分子生物技術鑑定植體根系與土壤微生物之菌相，試圖尋找可以促進植 物生長亦可以抵抗毒害之植物促生菌。以過氧化鈣結合生物激素與螯合劑提昇植 生復育處理受重金屬污染土壤，期能以整合型植生復育法做為後續研究之綠色整 治技術。
計畫英文摘要	Phytoremediation, a green technology developed to extract heavy metals from polluted soils, has drawn a great attention due to cost-effectiveness and aesthetically pleasing nature. The aim of this research intends to assess the potential of bioenergy plant sunflower to remediation soil polluted with a mixture of heavy metals. Several pretreatments to enhance phyotremediation efficiency including adding calcium peroxide, plant growth regulators, and evaluating plant growth promoting rhizobacteria will be employed. In this study two commercially available plant growth regulators will be used to boost the assisted phytoextraction of Pb, Cu, and Zn. The effects of calcium peroxide and chelant treatment in soil will be investigated in terms of dry weight biomass, and heavy meal accumulation in the plants. In addition, the transformation mechanisms via these treatments through the pilot-scale and field-scale systems will be studied to evaluate the phytoextration efficiency and transpiration rate. Heavy metals removed through the vegetation uptake and heavy metal soil mobility will be researched by employing sequential extraction to characterize the components that heavy metal is associated with. By virtue of understanding the mobility of heavy metals, the phytoremediation efficiency and potential environmental impact from the removed heavy metals can be addressed. The third year of this research will evaluate the potential of recycling the sunflower seeds as bioenergy and reusing the harvesting plants as biosorbents. Several related parameters, namely pH, redox potential, dissolved oxygen, microbial condition, to optimal operate laboratory-scale modules and field operation enhancing the pollutant removal will also be studied. The findings of this research might also provide the preliminary solution for combating the upcoming challenge to innovatively remediate soil pollution through phytoremediation via employing calcium peroxide, plant growth regulators, and chelants.
