Determination of the inhibition of the
mobility of daphnids was carried out with the substance. Test conducted
according to the OECD Guideline 202. The stock solution 100 mg/l was
prepared by dissolving colourless liquid in acetone. Test solutions of
required concentrationas were prepared by mixing the stock solution of
the test sample with reconstituted test water. The test substance was
tested at the concentrations 0, 0, 5, 10, 20, 40, 80 mg/L. Effects on
immobilisation were observed for 48 hours. The median effective
concentration (EC50) for the test substance benzyl 2-methylpropanoate,
in Daphnia magna was determined to be 20.5 mg/L for immobilisation
effects. This value indicates that the substance is likely to be
hazardous to aquatic invertebrates and can be classified as aquatic
chronic 3 category as per the CLP criteria. But as the chemical was
readily biodegradable thus it can be concluded that the chemical was
nontoxic and not classified as per the CLP classification criteria.
