This study which was carried out between July 2019 and April 2020 aimed to determine the seasonal changes of heavy metals (Cd, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Se, and Zn) in plant organs of Phragmites australis and Typha angustifolia grown in Eğirdir Lake and to research the usability of the these plants for phytoremediation with the calculation of bioaccumulation factor (BF). Plant samples were brought to the laboratory, and then washed, cleaned with distilled water, dried in an oven at 70 °C and acidified with 10 ml HNO. The samples were heated at 120 °C on a hot plate until completely mineralized. After mineralization, heavy metal concentrations were determined by using ICP-AES (Vista model). Only Mo was the highest in leaf, while other metals were highest in root in P. australis. In T. angustifolia, Mn and Mo were highest in the leaf, the accumulation of other metals was observed to be higher in the plant's roots than the other organs. It was discovered that the metal concentrations in root, in stem, and in leaf for both macrophytes generally increased in summer and decreased in root in autumn and winter and in stem and in leaf in spring for P. australis and in all organs in spring for T. angustifolia. Bioaccumulation factor (BF) values were calculated to determine the phytoremediation potential of P. australis and T. angustifolia. Both macrophytes are not excluder for all metals. Plants revealed potential for phytoremediation for the removal of heavy metals especially Mo and Zn. As a result of our study, it was determined that both macrophytes had accumulation abilities especially for Mo and Zn. It should be taken into consideration that these macrophytes can be used for improving the current situation of Eğirdir Lake due to their advantages such as being economical and not causing any harm to the environment.
本研究于 2019 年 7 月至 2020 年 4 月进行，旨在确定生长在埃杰迪尔湖的芦苇（Phragmites australis）和香蒲（Typha angustifolia）植物器官中重金属（Cd、Cr、Cu、Fe、Mn、Mo、Ni、Pb、Se 和 Zn）的季节性变化，并通过计算生物积累因子（BF）研究这些植物用于植物修复的可用性。将植物样本带到实验室后，先用蒸馏水洗净、清洁，然后在 70°C 的烘箱中干燥，并酸化至 10ml HNO。将样品放在加热板上加热至 120°C，直至完全矿化。矿化后，使用 ICP-AES（Vista 型）测定重金属浓度。在 P. australis 中，只有 Mo 在叶片中含量最高，而其他金属在根部含量最高。在 T. angustifolia 中，Mn 和 Mo 在叶片中含量最高，其他金属在植物根部的积累量高于其他器官。研究发现，两种大型植物的根、茎和叶中的金属浓度通常在夏季增加，在秋季和冬季减少，在 P. australis 的根部和茎部以及春季的叶片中减少，在 T. angustifolia 的所有器官中均在春季减少。为了确定 P. australis 和 T. angustifolia 的植物修复潜力，计算了生物积累因子（BF）值。两种大型植物对所有金属均不具有排斥性。这些植物对去除重金属，特别是 Mo 和 Zn 具有潜在的植物修复能力。根据我们的研究，确定两种大型植物对 Mo 和 Zn 的积累能力较强。由于其经济实惠且不会对环境造成任何危害等优点，应考虑将这些大型植物用于改善埃杰迪尔湖的现状。
