Certain plants have demonstrated the capability to take up and accumulate metals, thus offering the potential to remediate metal-contaminated water and sediment. Several aquatic species have further been identified which can take up metal and metal oxide engineered nanoparticles (ENPs). It is important to evaluate if aquatic plants exhibiting potential for metal phytoremediation can be applied to remediation of metallic ENPs. Understanding the interactions between ENPs and aquatic plants, and evaluating possible influences on metal uptake and phytoremediation processes is therefore essential. This review article will address the feasibility of green plants for treatment of ENP-affected aquatic ecosystems. Discussion will include common types of ENPs in current use; transformations of ENPs in aquatic systems; the importance of microorganisms in supporting plant growth; ENP entry into the plant; the influence of microorganisms in promoting plant uptake; and recent findings in phytoremediation of ENP-affected water, including applications to constructed wetlands.
某些植物已被证明具有吸收和积累金属的能力，因此有可能修复受金属污染的水和沉积物。此外，还进一步确定了一些能够吸收金属和金属氧化物工程纳米颗粒（ENPs）的水生物种。重要的是要评估是否可以将表现出金属植物修复潜力的水生植物应用于修复金属 ENPs。因此，了解 ENPs 与水生植物之间的相互作用，并评估对金属吸收和植物修复过程的可能影响至关重要。这篇综述文章将探讨绿色植物处理受 ENP 影响的水生生态系统的可行性。讨论将包括当前使用的常见类型的 ENPs；ENPs 在水生系统中的转化；微生物在支持植物生长方面的重要性；ENP 进入植物；微生物在促进植物吸收方面的影响；以及受 ENP 影响的水的植物修复的最新发现，包括在人工湿地中的应用。
