In this study, two aquatic macrophytes Phragmites australis and Schoenoplectus lacustris and corresponding sediment samples were collected every three months from Lake Sapanca (Turkey) and analysed for their heavy-metal contents (Pb, Cr, Cu, Mn, Ni, Zn and Cd). Accumulation factor ratios of plant parts were calculated for all metals, and the two species were compared in terms of accumulation properties. The highest concentrations were measured in the root systems while relatively low concentrations were found in the rhizome and above-ground parts of the plants. The accumulation ratios of root for P. australis were usually higher than the ratios for S. lacustris. While the accumulation ratios of root were higher in winter than in the other seasons for P. australis, for S. lacustris the highest accumulation ratios were found in the autumn. Both plant species were found to be root accumulators of Pb, Cu, Mn, Ni, Zn and Cd.
在本研究中，每隔三个月从土耳其萨潘卡湖采集两种水生大型植物芦苇和黑三棱以及相应的沉积物样本，并分析其重金属含量（铅、铬、铜、锰、镍、锌和镉）。计算了所有金属在植物各部位的积累因子比率，并比较了这两个物种的积累特性。在根系中测得的浓度最高，而在植物的根茎和地上部分发现的浓度相对较低。芦苇根部的积累比率通常高于黑三棱。芦苇根部的积累比率在冬季高于其他季节，而黑三棱的最高积累比率出现在秋季。发现这两种植物都是铅、铜、锰、镍、锌和镉的根部积累者。
