Metals in Sediment and Phragmites Australis (Common Reed) From Tisza River, Serbia

Abstract

Abstract. In this study the concentrations of metals were investigated in Phragmites australis (Cav.) Trin. eh Steud. 1841 and sediment samples from the bed of the River Tisza in Serbia. Al, As, B, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Sr and Zn levels were analyzed using inductively coupled plasma -optical emission spectrometry. The sediment samples contained elevated concentrations of cadmium, chromium, copper, nickel and zinc. The increased concentration of these metals had no significant effect on wildlife of the river Tisza as the determined concentrations of the metals tested in the comon reed do not exceed the threshold of phytotoxicity. The research proved a strong positive correlation between the concentrations of metals in the sediment and all common reed organs (rhizome, stem and leave). Accumulated metals in the common reed are not distributed evenly, but there are target organs for bioaccumulation. Concentrations in belowground organs were usually higher than aboveground organs, and the general decreasing trend of element content was rhizome>leaves>stems.

Assessment of Minor and Trace Elements in Aquatic Macrophytes, Soils and Bottom Sediments Collected along Different Water Objects in the Black Sea Coastal Zone by Using Neutron Activation Analysis

“…The studies of [15] [22] in the estuaries of Italian rivers affected by municipal wastewaters and agricultural activities showed a good correlation of Al, As, Cr, Cu, Mn, Ni and Zn in P. australis with the elemental content in corresponding sediments and water. Also a strong positive correlation between the concentrations of Al, As, Co, Cr, Cu, Fe, Mn, Ni, Se, Sr and Zn in the sediments and all organs (rhizome, stem and leave) of P. australis sampled from the Tisza River in Serbia was found by [23]. The investigations in the constructed wetland in North Italy [24] and in the Hokersar wetland, Ramsar site of Kashmir Himalaya, India [25] showed that P. australis is appropriate species for phytoextraction and phytoremediation of the environment.…”

“…were used. P. australis is one of the most distributed macrophytes in aquatic ecosystems, and numerous studies showed its capacity of trace element bioaccumulation [11] [13] [15] [19] [20] [21] [23]. Thus Duman [19] reported that the roots of Phragmites australis from fresh water Lake Sapanca in Turkey were found to be good accumulators of Cu, Mn, Ni, Zn.…”

“…To extend our studies regarding the elemental content of more than 35 elements for the territory of an important but poor investigated recreation zone of the Caucasian coast of the Black Sea, the aquatic macrophytes Phragmites australis, Carex conescens L as well as the green algae Cladophora sericea (Hudson) Kutzing were used. P australis is one of the most distributed macrophytes in aquatic ecosystems, and numerous studies showed its capacity of trace element bioaccumulation [19][20][21][22][23]. Thus Duman reported that the roots of Phragmites australis from fresh water Lake Sapanca in Turkey were found to be good accumulators of Cu, Mn, Ni, Zn.…”

Assessment of heavy metal pollution in sediments and their bioaccumulation in phragmites australis frome Nil river (Jijel- Algeria)

“…These results are in accordance with the findings of other studies demonstrating that accumulated metals in the common reed are not distributed evenly. The underground organ shows a higher storage capacity than the above ground parts (Štrbac et al, 2014;Kucaj et al, 2015). Nouri et al, (2009) reported that the root tissues accumulate higher concentrations of metals than shoots, which indicated greater plant availability of the substrate metals, as well as interior limited mobility of the plant.…”
