Kapulukaya Barajı Aşağı Havza’sı Sediment Örneklerinde Ağır Metal Kirlilik Düzeylerinin Değerlendirilmesi (Kızılırmak, Kırıkkale)

Bu çalışmada Mayıs 2013-Şubat 2014 tarihleri arasında Kızılırmak Nehri’nin Kırıkkale il sınırları içerisinde kalankısmında belirlenen altı istasyondan alınan sediment örneklerinde ağır metal kirlilik düzeyleri incelenmiştir. Al,Fe, As, Cr, Ni, Pb, Zn, Cd, Hg elementlerinin konsantrasyonları ICP-OES cihazı kullanılarak belirlenmiştir.Sonuçlara göre, Fe tüm istasyonlarda en yüksek konsantrasyonda birikim gösteren element olurken Hg, S1istasyonu hariç en düşük konsantrasyonda birikmiştir. Çalışmanın yapıldığı dönemde Kırıkkale iline ait atık suarıtma tesisi bulunmaması sebebiyle kanalizasyon atıkları doğrudan Kızılırmak Nehri’ne bırakılmaktaydı. Atıksuyun Kızılırmak Nehri’ne boşaltıldığı nokta, çalışmanın gerçekleştirildiği istasyonlardan S3 ile S4 arasında yeralmaktadır. Buna göre ilk üç istasyon (S1, S2, S3) ve son üç istasyon (S4, S5, S6) karşılaştırıldığında ortalamadeğerlerin Hg hariç arttığı belirlenmiştir. Mevsimsel olarak anlamlı farklılık sadece Zn elementi için ilkbahar ilesonbahar ve ilkbahar ile kış arasında tespit edilmiştir (p

Assessment of Heavy Metal Pollution Levels in Sediment Samples of Lower Catchment Area of Kapulukaya Reservoir (Kızılırmak, Kırıkkale)

In this study, heavy metal pollution levels were investigated in the sediment samples which taken from six different sites in the Kızılırmak River in Kırıkkale province, between May 2013 and February 2014. The concentrations of Al, Fe, As, Cr, Ni, Pb, Zn, Cd and Hg were determined by using ICP-OES. According to the results, Fe was the element showing the highest concentration in all stations, while Hg was the element with lowest concentration except S1 site. During the study, seweage effluents were left directly to Kızılırmak River due to the lack of waste water treatment plant belonging to Kırıkkale province. The point where waste water is discharged to Kızılırmak River is located between S3 and S4 sites where the study is carried out. Accordingly to the results, when the first three stations (S1, S2, S3) and the last three stations (S4, S5, S6) were compared, it was found that the average values increased except Hg. Seasonally significant difference was found only for Zn element between spring and autumn and spring and winter seasons (p
