Helophytic plants contribute significantly to the remediation of ecosystems through a wide range of physiological or biochemical mechanisms including the role of endophytic bacteria. This review highlights the services provided by Juncus spp. wetland plants, from phytoremediation of soils and groundwater with heavy metals and/or organics to municipal or industrial wastewater treatment in constructed wetlands. The data presented also provide information on the efficiency of specific Juncus spp. in response to various metals and organic compounds, in an effort to exploit the natural capabilities of autochthonous over exotic species in phytoremediation strategies. An overall successful direct (the plant itself) or indirect (through stimulation of elimination mechanisms) contribution of Juncus to remediation of the above contaminants is revealed. However, the specific characteristics of the species used, the type of the pollutant and the region, are issues that should be addressed for a successful outcome.
湿地植物通过广泛的生理或生化机制，包括内生细菌的作用，为生态系统的修复做出了重大贡献。本综述重点介绍了湿地植物灯心草属在土壤和地下水的重金属和/或有机物的植物修复，以及人工湿地中城市或工业废水处理方面的作用。所提供的数据还提供了关于特定灯心草属植物对各种金属和有机化合物的响应效率的信息，以努力利用土著物种相对于外来物种在植物修复策略中的自然能力。揭示了灯心草属植物对上述污染物修复的直接（植物本身）或间接（通过刺激消除机制）的总体成功贡献。然而，成功的关键在于所用物种的具体特征、污染物的类型和区域。
