Abstract:
This study was carried out to determine Zn accumulation capacity of Potamogeton pectinatus, Potamogeton perfoliatus and Groenlandia densa, grown in single and triple. The macrophytes used in the study were collected from the wetlands in Gaziantep and brought to the laboratory. 0, 5, 25 and 50 mg/L concentrations of Zn were applied to healthy macrophytes acclimated in a controlled climate chamber. It was determined that Zn content of macrophyte tissues grown under the effect of single and triple Zn concentrations increased with increasing the metal concentrations. Considering both applications, the Zn content of the macrophytes was found as G. densa>P. perfoliatus>P. pectinatus Besides, macrophytes have been found to accumulate more Zn in their tissues in single applications. In addition, the bioconcentration factors of macrophytes were calculated to decrease with increasing Zn concentration.
