Abstract

Bu çalışma sulama açısından uygunluğunu ve güvenirliliğini değerlendirmek amacıyla Kayacık Barajı’nın (Gaziantep, Türkiye) su kalitesini ve ağır metal kirliliğini belirlemek üzere yürütülen ilk çaraştırmadır. Bu amaçla, 2019 bahar döneminde 6 istasyondan alınan su örnekleri ICP-OES ile ağır metallerin (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb ve Zn) varlığının belirlenmesi için polietilen şişelere alınmıştır. Su sıcaklığı, pH, çözünmüş oksijen ve iletkenlik 8405 Combo Water Meter ile in situ ölçülmüştür. Ortalama su sıcaklığı, pH, çözünmüş oksijen ve iletkenlik değerleri sırasıyla 20.53oC, 8.30, 12.57 mg/L and 723.7 μS cm-1’dir. Sıcaklık, pH ve çözünmüş oksijen derğerleri açısından Kayacik Barajı birinci sınıf su kalitesine sahipken iletkenlik değerine göre ikinci sınıf su kalitesine sahiptir. Analiz edilen ağır metaller arasında Cd, Co, Cr, Cu ve Pb düzeyleri belirleme sınırının altında ölçülmüştür (0.05 mg/L). Kayacık Barajı’nda ağır metal derişimlerinin Mn>Fe>Al>Zn>Ni şeklinde olduğu bulunmuştur. İstasyonlar arasında ağır metal derişimlerinde genel olarak azalan ya da artan yönde bir değişim gözlenmemiştir. Gıda ve Tarım Örgütü (FAO) sulama suları için önerilen maksimum element derişimlerine göre değerlendirildiğinde Mn ve Ni düzeylerinin önerilen maksimum sınırın üzerinde olduğu, Fe, Al ve Zn değerlerinin izin verilen aralıkta olduğu değerlendirilmiştir.

Water Quality and Heavy Metal Pollution in Kayacik Dam (Gaziantep, Turkey)

Abstract

The present study was the first conducted to determine the water quality and heavy metal pollution in Kayacik Dam (Gaziantep, Turkey) to assess its suitability and safety for irrigation. For this purpose, water sampling from 6 stations was performed in spring 2019 and samples taken into polyethylene bottles were used to determine the presence of heavy metals (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) using ICP-OES. The water temperature, pH, dissolved oxygen, and conductivity were measured in situ via 8405 Combo Water Meter. The average values of water temperature, pH, dissolved oxygen, and conductivity were as follows; 20.53oC, 8.30, 12.57 mg/L, and 723.7 μS cm-1, respectively. Kayacik Dam was found to be first-class water quality in terms of temperature, pH, and dissolved oxygen while it can be evaluated as a second class in terms of conductivity. Among heavy metals analyzed levels of Cd, Co, Cr, Cu, and Pb were under the detection limit of 0.05 mg/L. The order of heavy metal levels in Kayacik Dam was found as Mn>Fe>Al>Zn>Ni. A general increasing or decreasing trend was not determined in heavy metal levels among stations. According to recommended maximum element concentrations for irrigation purposes by United Nations Food and Agricultural Organization (FAO), Mn and Ni levels were found to be higher than the maximum recommended level while Fe, Al, and Zn were in the allowable range.
