Investigation of Sediment Pore Water Heavy Metal (Cu and Pb) Geochemistry in Deriner Dam Lake

Abstract

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.

Deriner Baraj Gölü Ekosisteminde Sediment Gözenek Suyu Ağır Metal (Cu ve Pb) Jeokimyasının İrdelenmesi

Öz

Bu çalışmanın amacı, Deriner Baraj Gölü’nde sediment gözenek suyundaki metal kirliliği ve ekolojik riski belirlemektir. Deriner Baraj Gölü, Türkiye'nin kuzeydoğu Anadolu bölgesinde Çoruh Havzasında (Artvin) yer alır. Metal konsantrasyonlarını belirlemek için toplam 7 istasyon belirlenmiştir. Bu istasyonların 4 tanesi göl ortamından, 3 tanesi bu gölü besleyen akarsu kolundan seçilmiştir. Örnekler, Ekim 2016'da 1.5-60 m derinlik aralığında toplanmıştır. Metal konsantrasyonları, ACME analitik kimya laboratuarında ICP-MS yöntemi ile tespit edilmiştir. Sediment gözenek suyundaki Cu ve Pb'nin ortalama değerleri, literatürde yaygın olarak kullanılan gözenek suyu kimyası değerlerinden (WQC) daha yüksek bulunmuştur. Elde edilen metal değerleri sediment gözenek suyu kalite değerleri (SGV) ile kıyaslandığında Cu ve Pb'nin ortalama değeri orta derecede kontamine (B sınıfı) olarak tespit edilmiştir. İstasyonlara göre örnekleme alanındaki metal konsantrasyonları, A1, A3, A2, D3, D1, D2, D4 sırasına göre azalmaktadır. Bu çalışmanın sonuçlarına dayanarak, Cu ve Pb elementlerinin deriner baraj gölü için toksik etki gösterebileceği söylenebilir.
