- Validity criteria fulfilled:
- yes
- Conclusions:
- Based on nominal concentrations, experimental median lethal Concentrations [LC-50 (96 h)] for CAS No. 586-37-8 on Zebra Fish Danio rerio was determine to be 100 mg/l.
- Executive summary:
Study was conducted to access the effect of test chemical 3-methoxyacetophenone 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. Therefore, the test solution was prepared by dissolving 400 mg of the test substance in 4 liters of potable water (passed through reverse osmosis system) with continuous stirring. This test solution was then added to the remaining three liters of water for achieving test concentrations of 100 mg/L and Zebra FishDanio reriowere exposed to these concentration for 96 hours. 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 ( 3-methoxyacetophenone ) to nominal test concentration, LC50 was determine to be 100 mg/l . Based on the LC50, it can be consider that the chemical was not hazardous and can be consider to be not classified as per the CLP classification criteria.
