Limit Values of Dissolved Nutrients for the Assessment of Eutrophication in the Northeastern Mediterranean Rivers

Abstract

In this study, an attempt was made to determine limit values of dissolved nutrients for assessing trophic status and water quality of Northeastern Mediterranean Rivers from the previously published nutrient data sets. Study findings indicated that the oligotrophic river waters should have concentrations of total phosphorus, orthophosphate, ammonium and total nitrogen less than 0.13 mg/L, 0.07 mg/L, 0.11 mg/L and 0.90 mg/L, respectively. The proposed limit values defining oligotrophy, mesotrophy and eutrophy were different than the values reported by the Surface Water Quality Regulation and the commonly used reference values. These discrepancies were probably due to distinct physical and biochemical characteristics of the rivers. For defining threshold and reference values of dissolved nutrients, new approaches, such as modeling studies, are needed to produce more sensitive assessment tools for sustainable management of NE Mediterranean Rivers.

Kuzeydoğu Akdeniz Nehirlerinde Ötrofikasyonun Değerlendirilmesi için Çözünmüş Besin Tuzları Sınır Değerleri

Öz

Bu çalışmada, daha önce yayınlanan besin tuzu veri setlerinden Kuzeydoğu Akdeniz Nehirlerinin trofik durumunu ve su kalitesini değerlendirmek için sınır değerler belirlenmeye çalışılmıştır. Çalışma sonuçları, oligotrofik özellikte nehir sularının toplam fosfor, ortofosfat, amonyum ve toplam azot için konsantrasyon değerlerinin 0,13 mg/L, 0,07 mg/L, 0,11 mg/L ve 0,90 mg/L'den az olması gerektiğini göstermiştir. Oligotrofi, mezotrofi ve ötrofiyi tanımlayan önerilen sınır değerler, Yerüstü Kalitesi Yönetmeliği tarafından bildirilen değerlerden ve yaygın olarak kullanılan referans değerlerden farklı bulunmuştur. Bu farkılıkları muhtemelen nehirlerin farklı fiziksel ve biyokimyasal özelliklere sahip olmasından kaynaklıdır. Çözünmüş besin tuzlarının sınır ve referans değerlerinin tanımlanması ve Kuzeydoğu Akdeniz Nehirlerinin sürdürülebilir yönetimi için daha hassas değerlendirme araçları üretmek üzere modelleme çalışmaları gibi yeni yaklaşımlara ihtiyaç vardır.
