Phosphorus (P) overloading in fresh water systems has a detrimental effect by increasing the speed of eutrophication. Phytoremediation is the use of natural plants to remove contaminants from the environment. In the current study, we tested five plants (Pteris vittata, Lemna minor, Rumex orbiculatus, Rumex verticillatus, and Typha × glauca) in the laboratory and field for phosphorus mitigation potential. In the field experiment, both root and shoot phosphorus content were evaluated, and in the laboratory study percent phosphorus removed was calculated. Our research showed in both experiments that T. glauca removed the most phosphorus (p < 0.05). In the field study, shoots of T. glauca removed on average 3.7 g P/plant, while the roots and shoots removed 12.67 g P/plant from water. In the laboratory study, the T. glauca removed 84% of the phosphorus from the water. Rumex verticillatus in both experiments had the next highest phosphorus removal rates (0.46 g P/shoot, 1.93 g P/plant (root + shoot), and 90% removal in the laboratory study). These results show great potential for T. glauca and R. verticillatus in the mitigation of phosphorus from fresh water systems.

使用人工湿地植物在人工浮垫上进行磷素植物修复

淡水系统中的磷（P）超载会通过增加富营养化的速度而产生不利影响。植物修复是利用天然植物从环境中去除污染物。在目前的研究中，我们测试了五个工厂（蜈蚣草，浮萍，羊蹄藤，酸模verticillatus和香蒲×青冈）在实验室和现场减缓磷潜力。在田间试验中，评估了根和茎中的磷含量，并在实验室研究中计算了除磷百分比。我们的研究表明，在这两个实验中，T。glauca去除的磷最多（p <0.05）。在田间研究中，白花T. glauca的芽平均去除了3.7 g P /株，而根和芽从水中去除了12.67 g P /株。在实验室研究中，T。glauca从水中去除了84％的磷。在两个实验中，Rumex verticillatus的磷去除率均次高（在实验室研究中，磷去除率分别为0.46 g P /芽，1.93 g P /植物（根+枝）和90％去除）。这些结果表明，T。glauca和R. verticillatus在缓解淡水系统中的磷方面具有巨大潜力。
