Arundo donax as a potential biomonitor of trace element contamination in water and sediment.

摘要: Environmental monitoring through living organisms is an effective technique of human impact assessment, based on reliable and cost-effective biological tools control. In this study, roots, stems leaves the worldwide distributed macrophyte Arundo donax (giant reed) were tested as potential biomonitors trace element contamination in water sediment. particular, concentrations following elements analyzed: Al, As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Zn. A two-year sampling was conducted urban watercourse Catania (Sicily, Italy), affected by municipal industrial discharges wastewaters. Results showed that amount plant tissues significantly dependent kind organ element. Trace decreased according to pattern root>leaf>stem, implying roots acted main centers bioaccumulation, transit organs a consequence general high translocation from leaves. Overall, A. significant capacity bioaccumulation agreement with ecologically similar macrophytes. Positive correlations found between sediment (Al, Zn), (Cu, Zn). The results study suggested acts ecological indicator environmental conditions, thus, its application may prove useful tool during campaigns wetlands.
