Siflutrinin Zebra Balıkları (Danio rerio)’nda Akut Toksisitesinin Araştırılması

Öz

Siflutrin, su ekosistemlerini kirleten ve aynı zamanda potansiyel bir toksik kirletici olan sentetik bir piretroidtir. Bu çalışmada model bir organizma olan zebra balıklarında (Danio rerio) siflutrin kimyasalının 0,5, 1, 5, 10, 20 ve 50 µg/L olan dozlama çözeltilerinin 96 saat süreyle birikim değerlerinin hesaplanması amaçlanmıştır. Deneyler üç tekrarlı olarak yapılmış ve akut toksisite testinde statik test yöntemi kullanılmıştır. Aynı zamanda balıklarda tüm siflutrin konsantrasyonlarında yüzme hızında azalma, yan ve dip kısımda yüzme gibi davranış değişiklikleri gözlemlenmiştir. Siflutrinin akut toksisite testlerinden elde edilen veriler Probit Analizi İstatistik Yöntemi kullanılarak değerlendirilmiştir. Zebra balığının 96 saatlik LC50 değeri 3,61 µg/L olarak hesaplanmıştır.

Investigation of Acute Toxicity of Cyfluthrin on Zebrafish (Danio rerio)

Öz

Cyfluthrin is a synthetic pyrethroid that pollutes aquatic ecosystems and is also a potential toxic pollutant. Zebrafish (Danio rerio) were used in acute toxicity tests for bioassays. 96-hour LC50 values were determined for zebrafish. Experiments were performed in triplicate and the static test method of acute toxicity test was used. At the same time, behavioral changes were observed at each cyfluthrin concentration in fish. Data from cyfluthrin acute toxicity tests were evaluated using the Probit Analysis Statistical Method. The 96-h LC50 value for zebrafish was calculated as 3.61 µg/L.
