Özet
This study determined arsenic, chromium, cadmium, copper, zinc, nickel and lead concentrations in the sediment of the lake and river and evaluated their ecological risk profile and compared the ecological risk profile of some potentially toxic elements accumulated in surface sediment of stagnant and running water ecosystems in the Meriç Delta Wetland, Turkish Thrace which is located in the European part of Turkey and have two important river systems, Meriç and Ergene, which provide freshwater resources for the region. Sediment samples were taken seasonally from three stations (one station from the river and two stations from the lake) in 2020. Ecological and biological risk analyses were calculated using the potential ecological risk index (RI), biological risk index (mERM-Qi), contamination factor (CF), contamination degree (CD) and pollution load index (PLI). As a result, although RI stated that Cd was determined as the riskiest element and mERM-Qi stated that Zn was determined as the riskiest element, indicated that there were no high ecological risks besides the investigated elements in the area. Although it is expected that the sediment quality of running water systems is better than that of stagnant water systems, the results of risk indices in the present study showed that the station selected for running water was the riskiest station in terms of potentially toxic elements.
