Abstract:
The paper deals with Cu and Zn content analysis in water, sediment and tissue of Phragmites communis Trin., Salvinia natans (L.) All. and Utricularia vulgaris L. in the area of Bardača fish pond (Necik and Sinjak- active fish ponds). Based on measured value of Cu in water, and according to the Regulation on Classification of Water and Water Streams, researched localities belong to category II waters, and based on the Zn content to category III/ IV waters. The content of copper and zinc in sediments did not exceed the maximum permitted concentration values according to the RS Official Gazette (23/1994). Obtained results indicate that Cu and Zn content in plant tissue significantly varied in relation to species, locality and sampling period. Species Salvinia natans has shown to be the best Zn bioaccumulator, while Utricularia vulgaris accumulated copper the best, which indicates the existence of different trend in terms of accumulation of certain heavy metals during season in different organs and tissues. The role of different types of aquatic macrophytes in heavy metal accumulation during season was emphasized here and their potential of application in phytoremediation technique.
