- Validity criteria fulfilled:
- yes
- Conclusions:
- Based on nominal concentration, experimental median lethal Concentrations [LC-50 (96 h)] for 1-(3-hydroxyphenyl)ethanone on Zebra Fish Danio rerio was determine to be 100 mg/l.
- Executive summary:
Study was conducted to assess the effect of test chemical 1-(3-hydroxyphenyl)ethanone on the mortality 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 one hour stirring for achieving test concentrations of 100 mg/L, respectively. Potable water (passed through reverse osmosis system) was used and Zebra Fish Danio rerio were exposed to these concentration for 96 hours. Plastic aquaria were loaded with 8 fishes. A static procedure was used for the study. Test consider to be valid as it fulfilled all the necessary criteria. The mortality in the control was found to be 0 per cent at the end of the test. Constant conditions was maintained throughout the test and, static procedures used. The dissolved oxygen concentration was found to be 78.3 per cent of the air saturation value throughout the test. After 96 hours of exposure to test item 1-(3-hydroxyphenyl)ethanone to limit test concentration 100 m/l, LC50 was determine to be 100 mg/l. Based on the LC50 value, it can be consider that the chemical was toxic, but the chemical was readily biodegradable in water thus on that criteria chemical consider to be nontoxic and not classified as per the CLP classification criteria.
