The aim of this study was to investigate seasonal heavy metal accumulation and translocation characteristics of the narrow-leaved cattail (Typha angustifolia L.). Sediment and plant samples were taken seasonally from six different locations identified for this purpose, and Pb, Cr, Cu, Ni, Zn, and Cd concentrations as well as accumulation factor (AF) and translocation factor (TF) values were determined. It was noted that the metal concentrations in the plant roots, rhizomes, and leaves differed seasonally. The metals mainly accumulated in the plant roots, and Zn was the element that accumulated the most in the plant roots, rhizomes, and leaves. The highest Zn concentration was observed to be 56.47 μg g⁻¹ in the rhizome sample from the summer. In all the seasons, the AF value of Cd was observed to be above 1. In addition, the TF value was below 1 for all elements in every season. While the element having lowest uptake and translocation ratio was Cr, and the highest uptake and translocation ratio was found for Cd. The AF and TF values suggest that the plant would be most appropriate for use in phytostabilization.
