The phytoremediation role of aquatic plants in situ is extremely important today when, due to repeated droughts and periodical shrinkage of surface water resources, the load of biogenic and toxic substances in these waters is increasing dramatically. The aim of the study was to assess the bioaccumulation of heavy metals (Cd, Cr, Cu, Hg, Mn and Zn) by the Groenlandia densa reintroduced in the area of its historical occurrence in the habitat of rivers characterized by Ranunculion fluitantis vegetation. Research material was collected from 3 sites in the Natura 2000 area in Western Pomerania on areas differing in anthropogenic load, from sites on streams in agricultural, urbanized and forested catchments. The study showed varying content of trace metals in Groenlandia densa. Plants and sediments collected from the site with the highest anthropogenic load, located in an urbanized catchment, contained more metals. The tolerance of Groenlandia densa to elevated Mn levels in water/sediment was confirmed.

西波美拉尼亚重新引入的Groenlandia Densa植物中微量金属的生物富集

今天，由于反复干旱和地表水资源的周期性萎缩，这些水域中生物和有毒物质的负载急剧增加，因此水生植物在原地的植物修复作用极为重要。该研究的目的是评估重金属（镉，铬，铜，汞，锰，锌）通过的生物蓄积Groenlandia致密重新引入在其历史发生的区域在河流特征在于栖息Ranunculion  fluitantis植被。研究材料是从西波美拉尼亚Natura 2000地区三个地区的人为负荷不同的地区收集的，这些地区的土地来自农业，城市化和森林集水区的河流。研究表明，其中痕量金属的含量各不相同。Groenlandia densa。从人为负荷最高的地点收集的植物和沉积物位于城市化的集水区，含有更多的金属。证实了格氏land对水/沉积物中锰含量升高的耐受性。
