Assessment of Regional Water Resources and Eco-Biological Parameters in İstanbul

Öz

In this study was done between January and December 2013; Topuzlu and Neşetsuyu Springs of phytoplankton, epilitic, epipelic algae and water quality parameters were determined. It was found to be totally 27 taxa in Topuzlu Spring  and  21 taxa in Nesetsuyu Spring.  Generally in both research area Ochrophyta members were dominant organisms. In both springs,  Cocconeis pediculus,  Gomphonema olivaceum  in epilithic and Oscillatoria  prolifica, Euglena acus in epipelic samples were found.  Pyhsicochemical parameters were measured in the springs.  Average dissolved oxygen (9.2 mg l⁻¹) and  pH (7.2) and water temperature (14.2 ⁰C) and electrical conductivity (134.4 µS/cm) was determined in Topuzlu Spring. In the Neşetsuyu spring average dissolved oxygen (9.4 mg l⁻¹) and  pH (7.2) and water temperature (12.5 ⁰C) and electrical conductivity (130.1 µS/cm) was determined. The study, which has been carried out to determine hydrobiological features of the springs, has also great importance as being the first study.

İstanbul’da Bölgesel Su Kaynakları ve Eko-Biyolojik Parametrelerin Değerlendirilmesi

Öz

Ocak - Aralık 2013 tarihleri arasında yapılan bu çalışmada;Topuzlu Kaynağı ve  Neşetsuyu kaynağının, phytoplankton,epilitik, epipelik ve su kalitesine ait parametreler belirlenmiştir. 27 taxon Topuzlu Kaynağında, 21 taxon Neşetsuyu kaynağında tespit edilmiştir. Her iki kaynakta da  Ochrophyta üyeleri baskın olarak belirlenmiştir.  Her iki kaynakta,  Cocconeis pediculus,  Gomphonema olivaceum  epilitik,  Oscillatoria  prolifica, Euglena acus  epipelik örneklerde tespit edilmiştir.  Kaynaklarda, fizikokimyasal parametreler ölçülmüştür. Topuzlu kaynağında yapılan ölçümlerde  yıllık ortalama çözünmüş oksijen (9.2 mg l⁻¹), pH (7.2), su sıcaklığı (14.2 ⁰C) ve  iletkenlik (134.4 µS/cm) olarak belirlenmiştir. Neşetsuyu kaynağında, çözünmüş oksijen (9.4 mg l⁻¹), pH (7.2), su sıcaklığı (12.5 C⁰) ve iletkenlik  (130.1 µS/cm) olarak tespit edilmiştir. Bu çalışma hidrobiyolojik yapının belirlenmesi amacıyla, bu kaynaklarda yapılan ilk çalışma olması bakımından oldukça önemlidir.
