Bu çalışmada, Gediz Nehri'ndeki kirlilik, Daphnia magna toksisite testleri kullanılarak değerlendirilmiştir. Su örnekleri, ilkbahar ve yaz mevsimlerinde beş farklı istasyondan toplandı. Fe, Mn, Cl⁻, NH₃-N, S²⁻, K, NO₃⁻-N ve PO₄³⁻ gibi temel kimyasal bileşenlerin konsantrasyonları spektrofotometrik yöntemlerle belirlendi. Akut ve kronik toksisite testleri OECD yönergelerine uygun olarak gerçekleştirildi. Akut toksisite, ilkbaharda birden fazla istasyonda ve yazın bir istasyonda gözlendi. Buna karşılık, kronik maruziyet sonuçları, Gediz Nehri’nde bilinen organik ve inorganik kirliliğe rağmen D. magna üzerinde anlamlı olumsuz etkiler göstermedi. İlginç bir şekilde, bazı örnekler test organizmalarında büyüme, gelişim ve üremenin uyarıldığını ortaya koydu; bu durum, suda düşük konsantrasyonlarda bulunan ve sedimentlerde daha fazla yoğunlaşan kirleticilerden kaynaklanan hormetik etkileri işaret etmektedir. Bu bulgular, yalnızca su kolonuna dayalı Daphnia toksisite testlerinin, Gediz Nehri'nde bulunan organik ve inorganik kirleticilerin birleşik etkilerini tam olarak yansıtamayabileceğini ortaya koymaktadır.

In this study, pollution in the Gediz River was assessed using Daphnia magna toxicity tests. Water samples were collected from five distinct stations during spring and summer. Concentrations of key chemical constituents, including Fe, Mn, Cl⁻, NH₃-N, S²⁻, K, NO₃⁻-N, and PO₄³⁻, were determined spectrophotometrically. Acute and chronic toxicity tests were conducted according to OECD guidelines. Acute toxicity was observed at multiple stations in spring and at one station in summer. Conversely, chronic exposure results revealed no significant adverse effects on D. magna, despite the known organic and inorganic pollution in the Gediz River. Interestingly, some samples demonstrated stimulation of growth, development, and reproduction in the test organisms, indicating hormetic effects caused by low pollutant concentrations in the water, which are more concentrated in sediments. These findings underscore that Daphnia-based water-column toxicity tests alone may not fully capture the combined impacts of organic and inorganic contaminants present in the Gediz River.
