Berdan Çayi (Tarsus - Mersin) Sedimentinde Ağir Metal Düzeylerinin Araştirilmasi

Abstract

Ozet Bu calismada Mersin Ili'nin onemli akarsularindan birisi olan Berdan Cayi'nda mevsimsel olarak toplanan sediment orneklerinde Kadmiyum (Cd), Krom (Cr), Mangan (Mn), Nikel (Ni), Cinko (Zn), Bakir (Cu), Kursun (Pb), Demir (Fe) ve Aluminyum (Al) gibi agir metallerin birikim duzeyleri arastirilmistir. Calisma sonuclarina gore sedimentte agir metal birikim duzeyleri, Fe; 18521,91 μg/g, Al;12907,70 μg/g, Mn; 377,40 μg/g, Ni; 167,68 μg/g, Cr; 57,81 μg/g, Zn; 45,59 μg/g, Cu; 28,38 μg/g, Pb; 22,82 μg/g ve Cd; 4,54 μg/g olarak tespit edilmis ve agir metaller Fe>Al>Mn>Ni>Cr>Zn>Cu>Pb>Cd olarak siralama gostermistir. Sonuc olarak Berdan Cayi'nin kirlilik tehdidi altinda oldugu saptamistir. Anahtar Kelimeler: Agir metal, Berdan Cayi, sediment. Investigation of Heavy Metal Levels in Sediment of the Berdan River (Tarsus- Mersin) Abstract In the study, samples were seasonally taken from Berdan River- which is one of the major rivers in the province of Mersin -and accumulation levels of heavy metals such as Cadmium (Cd), Chromium (Cr), Manganese (Mn), Nickel (Ni), Zinc (Zn), Copper (Cu), Lead (Pb), Iron (Fe) and Aluminum (Al) were determined in sediment samples According to results of the study, heavy metal accumulation levels in the sediment Fe; 18521.91 μg/g, Al;12907.70 μg/g, Mn; 377.40 μg/g, Ni; 167.68 μg/g, Cr; 57.81 μg/g, Zn; 45.59 μg/g, Cu; 28.38 μg/g, Pb; 22.82 μg/g and Cd; 4.54 μg/g were fasten down and heavy metals were in the sequence as follows: Fe>Al>Mn>Ni>Cr>Zn>Cu>Pb>Cd. Finally, it has been observed that Berdan River is under the threat of pollution.
