- Validity criteria fulfilled:
- yes
- Conclusions:
- Based on nominal concentrations, experimental median lethal Concentrations [LC-50 (96 h)] for test material on Zebra Fish Danio rerio was determine to be >39.42 mg/L. LC100 (96 hours) (lowest loading at which 100% mortality was observed) = 51.4 mg/L.
- Executive summary:
Study was conducted to access the effect of test chemical on the growth of fish Danio rerio. Test conducted according to OECD Guideline 203 (Fish, Acute Toxicity Test). The test substance was soluble in water. Initially, stock solution was prepared by dissolving 1g of the test substance in 1 liter of potable water (passed through reverse osmosis system) with continuous stirring. From this stock solution, further test concentration was prepared for achieving test concentrations of 18 mg/L, 23.4 mg/L, 30.42 mg/L, 39.54 mg/L & 51.4 mg/L, respectively. Bowl aquaria containing 2 liters of potable water (passed through reverse osmosis system) were loaded with 8 fishes. A static procedure was used for the study and it was conducted in compliance with the OECD guideline 203. After 96 hours of exposure to test item to various nominal test concentrations 18 mg/L, 23.4 mg/L, 30.42 mg/L, 39.54 mg/L & 51.4 mg/l
LC50 was determine to be >39.42 mg/l . Based on the LC50, LC100 (96 hours) (lowest loading at which 100% mortality was observed) = 51.4 mg/L it can be consider that the chemical was toxic and can be consider to be classified aq aquatic chronic 3 as per the CLP classification criteria.
