The acute
toxicities of zinc oxide nanoparticle (ZnO NP), zinc chloride (ZnCl2)
and their mixtures of different concentrations (0.75, 1.5, 3, 6 and 12ppm) on Daphnia
magna (Straus, 1820) were investigated at 24, 48 and 72 hours by employing
the static acute toxicity test. The data obtained were statistically evaluated
by probit analysis method (SPSS 21.0v). The highest toxicity was found at 72
hours of the mixture (ZnO NP+ZnCl2) and the lowest toxicity was
found at 24 hours of ZnCl2. When the overall acute toxicity results
were considered, ZnO NP was determined to be more toxic than ZnCl2
and mixtures were determined to be more toxic than these two pollutants alone.
When the results of time-dependent acute toxicity were evaluated, toxicity was
found to increase with increasing time for all three experimental groups (ZnO
NP, ZnCl2 and ZnO NP+ZnCl2).
Bu çalışmada çinko oksit
nanopartikülünün (ZnO NP), çinko klorürün (ZnCl2) ve karışımlarının,
farklı konsantrasyonlarda (0,75, 1,5, 3, 6 ve 12ppm) Daphnia magna (Straus, 1820) üzerine akut toksik etkileri 24., 48.
ve 72. saatlerde statik akut toksisite testi kullanılarak araştırılmıştır.
Veriler probit analiz metodu kullanılarak istatistiksel olarak
değerlendirilmiştir (SPSS 21.0v). En yüksek toksisite karışımın (ZnO NP+ZnCl2)
72. saatinde, en düşük toksisitenin ise ZnCl2'nin 24. saatinde
olduğu tespit edilmiştir. Akut toksisite sonuçları göz önüne alındığında, D. magna üzerine ZnO NP'nin ZnCl2'ye
göre, karışımlarının ise bu iki kirleticiye göre daha toksik olduğu tespit
edilmiştir. Zamana bağlı akut toksisite sonucu değerlendirildiğinde her üç
deney grubu (ZnO NP, ZnCl2 ve ZnO NP+ ZnCl2) için zaman
arttıkça toksisitenin de arttığı belirlenmiştir.
