摘要：The study of bottom sediments and organs of Sparganium erectum carried out in the summer of 2014 in the city of Lębork, located in Northern Poland.The aim of this study was to evaluate the content of macroelements and heavy metals in the leaves, rhizomes and roots S.erectum and in bottom sediments of the Łeba River as well as comparison of accumulation and translocation factors of N, P, K, Mg, Ca, Zn, Ni, Cu, Mn, Fe, Cd and Cr in researched organs of aquatic plant.The use of S.erectum for biomonitoring and phytoremediation has also been considered.The results of Mann Whitney U test showed a number of statistically significant differences in the content of chemical elements in the leaves, rhizomes, roots and in bottom sediments.The macroelements are mainly accumulated in leaves and heavy metals are accumulated in roots and rhizomes of S.erectum.Increased Mn and Fe content in roots and rhizomes of S.erectum, in relation this physiological needs, refers to the beneficial effects of this species in the water treatment and sludge from the bottom sediment of manganese and iron compounds.The obtained bioconcentration and translocation factors values allowed to state that S.erectum can be used for phytoremediation of contaminated bottom sediments because retains metals in their roots and limit Mn and Fe mobility from roots and rhizomes to leaves once absorbed by roots of plant.
