Abstract (2. Language): 
Thirty surface sediment samples from the Ziqlab Dam area were collected and analyzed for nine: elements (Pb, Cd, Zn, Mn, Ni, Cu, Fe, Cr, and Co). Metal separation was determined by sequential fraction, The fractions are, a) exchangeable, b) carbonate» c) Fe / Mn oxides d) organic, and e) residual. The advantage of using these fractions is to provide the mechanism of association of metals with the minerological phases of the sediments. Concentrations of the elements are within, allowable levels except for1 Pb, Cd. and. Zn and in. some locations Ni. Most of the elements were found to be in the residual fraction which clearly indicates that, these metals are primarily immobile and have or bear the least bioavailability.

Abstract (Original Language): 
Ziglab Baraj alanından 31 yüzey sediman örneği toplanarak 9 element için (Pb, Cd, Zn, .Mn, Ni, Cu, Fe, Cr ve Co) analiz edilmiştir.. Metal ayrımı sıralı ayrımlamaya göre yapılmıştır. Ayrımlamalar a) değiştirilebilir, b) kanbonat, c) Fe/Mn oksitlen d) organik ve e) kalıntı sırasıyla gerçekleştirilmiştir.. Bu ayrımlamaları kullanmanın yararı, metallerin sedimanlerdeki mineralojik tarzlarla bir arada bulunma mekanizmasını dikkate almasıdır. Elementlerin değişimi Pb, Cd ve Zn ve bazı alanlarda Ni dışında izinverilebilir sınırlar içindedir.. .Metallerin çoğu kalıntı kısımda bulunmuştur.. Bu da, bu metallerin başlıca hareketsiz ve biyolojik aktivîteye katılımın en düşük düzeyde olduğunu açıkça göstermektedir,
