Abstract

The study aimed to interpret the abundance and
provenance of harmful elements in the bed sediments of the Ankara Stream. Average
Zn, Ni, Cu, Pb, As, Co and Cd values in the Ankara
Stream sediments are calculated as 111, 65.7, 32, 17.6, 16.4, 16.1 and 0.2 ppm,
respectively. The Al/Si ratio of the examined samples exhibit a
positive correlation with Cu, Pb, Ni and Co, and
TOC content of the examined samples shows a positive correlation with Cu, Pb ve Zn. The EF and I_geo values indicated that the
sediments were significantly polluted by As and Ni and generally moderately
polluted by Co, Zn, and Cu, and locally moderately polluted by Pb and Cd. Pb
anthropogenic contribution was estimated at an average of >100% in the
sediments. Therefore, Pb, Cu, Zn, and Co elements are generally
geologically sourced and there is locally an anthropogenic contribution.
Cadmium is mostly anthropogenic but partly a geological contribution, but it is
thought that Ni and As are completely anthropogenic sourced.

Ankara Çayı Dere Yatağı Sedimanlarının Zararlı Element İçeriği

Abstract

Bu çalışmanın amacı,
Ankara Çayı dere yatağı sedimanlarının içermiş olduğu zararlı elementlerin
bolluğunu ve kaynağını yorumlamaktır. Ankara Çayı dere yatağı sedimanlarının
ortalama Zn, Ni, Cu, Pb, As, Co ve Cd değerleri sırasıyla 111, 65.7, 32, 17.6,
16.4, 16.1 ve 0.2 ppm olarak hesaplanmıştır. İncelenen örneklerin Al/Si oranı
ile Cu, Pb, Ni ve Co arasında ve TOK içeriği ile Cu, Pb ve Zn arasında pozitif
ilişki gözlenmektedir. Zararlı elementlerin ZF ve Ijeo değerlerine göre söz
konusu sedimanlar As ve Ni bakımından önemli, Co, Zn, ve Cu bakımından genel
olarak orta, Pb ve Cd bakımından lokal olarak orta derecede kirlenmiştir. Sedimanlardaki
ortalama antropojenik (insan kaynaklı) Pb (%) değeri >100% olarak tespit
edilmiştir. Dolayısıyla Pb, Cu, Zn, ve Co elementleri genel olarak jeolojik
kaynaklı olmakla beraber yer yer antropojenik katkı söz konusudur. Cd çoğunlukla
insan kaynaklı olmakla beraber kısmen jeolojik katkı görülmektedir, ancak Ni ve
As’nin tamamen insan kaynaklı olduğu düşünülmektedir.
