Investigation of Sediment Pore Water Heavy Metal (Cu and Pb) Geochimistry in Deriner Dam Lake, Artvin, Turkey

The aim of this study was to determine metal pollution and ecological risk in the limnetic sediment pore water around Deriner Dam Lake. The Deriner Dam Lake is located in the Coruh Basin (Artvin) in northeastern Anatolia in Turkey. Cu and Pb concentrations were determined in a total of 7 stations, 4 of which were in the lake and 3 of which in the stream that was lake feeding. The samples were collected a range of 1.5-60 m depth, as October 2016. Metal concentrations were determined using an inductively coupled plasma-mass spectrometer (ICP-MS) analysis in ACME. Mean values of Cu and Pb in limnetic sediment pore water were higher than reference value pore water chemistry (WQC). According to sediment guidance values (SGV), mean values of Cu and Pb were determined as class B- moderately contaminated. According to stations, the metal concentrations in sampling area decrease in the order A1, A3, A2, D3, D1, D2, D4. Based upon the results from the present study Cu and Pb can be considered as the contributor to toxicity around the Deriner Dam Lake.
