Use of Bio – Ecological Risk Indices to Evaluate the Sediment Quality of Seydisuyu Stream Basin

Öz

Many indices have been developed to evaluate the environmental risks of toxic elements in sediments.
Potential Ecological Risk Index and Biological Risk Index are two of the most widely used sediment indices used
to evaluate the environmental risks. Seydisuyu Stream that is one of the most important branches of Sakarya River
is located on the Eskişehir Province and exposed to an intensive agricultural, domestic and industrial pollution.
The aim of the present study is to evaluate the sediment quality of Seydisuyu Stream Basin by using Potential
Ecological Risk Index and Biological Risk Index. For this purpose, sediment samples were collected in summer
season of 2012 from 15 stations selected on Seydisuyu Stream Basin (2 of them from the Kunduzlar Dam Lake and
3 of them from the Çatören Dam Lake) and some toxic element accumulations (arsenic, chromium, copper, lead,
zinc, cadmium and nickel) in sediment samples were investigated. The Potential Ecological Risk Index (PERI) and
Biological Risk Index (BRI) applied to the results to assess the environmental risks of heavy metals in the region.
According to the results of PERI, chromium and cadmium, and according to the results of BRI, chromium, nickel
and lead are the most risky elements for the Seydisuyu Stream Basin.

Biyo – Ekolojik Risk İndeksleri Kullanılarak Seydisuyu Havzası Sediment Kalitesini Değerlendirilmesi

Öz

Sedimette birikim gösteren toksik metallerin çevresel risklerini değerlendirmek için birçok indeksler
geliştirilmiştir. Potansiyel Ekolojik Risk İndeksi ve Biyolojik Risk İndeksi çevresel riskleri değerlendirmek için
kullanılan en yaygın sediment indekslerinden ikisidir. Eskişehir’de yer alan ve Sakarya Nehri’nin en önemli
kollarından olan Seydisuyu Çayı, yoğun bir tarımsal, evsel ve endüstriyel kirliliğe maruz kalmaktadır. Bu çalışmanın
amacı, Potansiyel Ekolojik Risk İndeksi ve Biyolojik Risk İndeksi kullanılarak, Seydisuyu Çayı Havzası’nın
sediment kalitesinin değerlendirilmesidir. Bu amaçla, 2012 yılının yaz mevsiminde, havza üzerinde belirlenen 15
istasyondan (2 istasyon Kunduzlar Baraj Gölü’nden ve 3 istasyon Çatören Baraj Gölü’nden) sediment örnekleri
alınmış ve bazı toksik element içerikleri tespit edilmiştir (arsenik, krom, bakır, kurşun, çinko, kadmiyum ve nikel).
Bölgede ağır metallerin çevresel riskleri değerlendirmek için elde edilen veriler kullanılarak, Potansiyel Ekolojik
Risk İndeksi (PERİ) ve Biyolojik Risk İndeksi (BRİ) hesaplanmıştır. Elde edilen PERİ verilerine göre, krom ve
kadmiyum, elde edilen BRİ verilerine göre ise, krom, nikel ve kurşun, Seydisuyu Çayı Havzası için en riskli ağır
metaller olarak tespit edilmiştir
