Composition of water, soil, and reed samples were examined to understand how plants behave in a contaminated environment compared to natural habitats and to show the influence of constructed wetlands on water quality. In soil samples, the same or higher concentration differences were detected as in water samples. The higher concentrations of P, K, Mn, Zn, and Cu in the constructed environment were detected in every plant part. It seemed that the element concentrations of root and leaves are the most appropriate bio-indicators of the elements and their availability in the environment. Vegetated beds operated better in element removal than nonvegetated beds, and the purification efficiencies calculated by mass and water flows were higher by 15-50% in every parameter. This calculation method provides more typical and reliable results on the real operation of the system than those values calculated by applying concentration values.
