In the present study, Pb, Cu, Cr and Ni accumulation capabilities of aquatic macrophytes Potamogeton pectinatus, Potamogeton perfoliatus and Groenlandia densa (Potamogetonaceae) were determined separately after treated with both single and triple. The macrophytes were treated with Pb, Cu, Cr and Ni at 0, 5, 25 and 50 mg/L concentrations in a controlled chamber during 4-days. The tested heavy metals were differently accumulated by macrophytes. The maximum Pb, Cu, Cr and Ni accumulations were determined in G. densa tissues followed by P. perfoliatus and P. pectinatus in both macrophyte treatments. In both macrophyte applications, mean accumulation values of the heavy metals in the macrophyte tissues decreased according to this sequence: Pb > Cu > Ni > Cr. Bioconcentration factor (BCF), which indicates the efficiency of macrophyte to accumulate the metal, were decreased with increasing external metal concentrations. According to this, Potamogetonaceae species had a high bioaccumulation potantial at low metal concentrations. On the other hand, metal accumulations in individual macrophytes were generally found to be higher than combined macrophytes. As a result, it can be said that macrophytes treated individually can accumulate more metal than combined ones.
