Acute and chronic toxicity of contaminated fresh water and sediment of Nif brook on Daphnia magna (Straus, 1820)
Nif Çayı Endüstriyel, evsel ve tarımsal deşarjlar ile doğrudan kirlenmektedir. Çayın suyunun evsel ve endüstriyel alanlarda sulama ve yıkama suyu olarak kullanılması rahatsızlık verici boyuttadır, bu nedenle doğal populasyonlar için potansiyel toksisitesinin bilinmesi büyük öneme sahiptir. Bu çalışmanın amacı Nif Çayı su ve sediment örneklerinin su piresi Daphnia magna kullanılarak toksisitesinin belirlenmesidir. Su ve sediment örneklerinin letal toksisitesi 48-saat akut test, subletal toksisite ise 7-gün kronik test ile gerçekleştirilmiştir. D.magna kullanılarak yapılan 48 saat Akut test sonuçlarına göre LC 50 değerleri su örnekleri için 6.8 ile 12.67 μl/L arasında sediment örnekleri içn 6.826 ile 38.038 μg/L arasında bulunmuştur. Subletal konsantrasyonlara maruz bırakılarak yapılan kronik testler sonucunda tüm istasyonlardan alınan su ve sediment örneklerin canlının üremesi üzerine negatif etkisi olduğu gözlenmiştir. Elde edilen veriler ışığında bu deneme sisteminin rutin kirlilik belirleme çalışmaları için uygunluğu tespit edilmiştir.

Nif çayi kirletilmiş tatlı su ve sedimentinin Daphnia magna (Strauss, 1820) üzerine akut ve kronik toksisitesi
The water and sediment of Nif Brook (Izmir, Turkey) is polluted by effluents have been discharged directly or treated from industrial, domestic and agricultural sources. As the water of the brook used for domestic and industrial water supply as well as for purpose of irrigation, it has a great importance to know the toxicity potential on the natural populations. The aim of this study is to define the water and sediment toxicity of certain streams Nif Brook by using the water flea Daphnia magna Strauss as a test organism. The toxic contents of collected water were diluted and sediments were used as an extract. The lethal toxicity of waters and sediments were evaluated by using the 48- h acute toxicity test. And also sub-lethal toxicity of waters and sediments were evaluated by using 7-days chronic toxicity test. According to acute test results average 48 h LC50 for D.magna between 6.8 to 12.67 μl/L for water samples, between 6.83 to 38.0 μg/L for sediment samples of 4 stations in Nif Brook were found and then D.magna were exposed to sub-lethal concentrations of 4 stations in this stream, the results show that all of the streams and their elutriates produced negative effects. Results of this study showed that, screening the toxicity of polluted waters and sediments by using D.magna gives better and more meaningful results than an quantitative analyze of toxic matters.
