EC50 (48h) > 100 mg/l

Key value for chemical safety assessment

Additional information

No information on "short-term toxicity to aquatic invertebrates" is available for the Target Substance. However data on Similar Substance 02 has been taken into account for the assessment. More details about the similarity between the two substances are reported in section 13.

The test substance was tested in acute immobilisation test on Daphnia magna. The test was performed according to OECD guideline 202.

The preliminary test was performed in a range of the test substance nominal concentrations 1 – 100 mg/l. The test was performed as static. Based on no toxicity of the test substance found in the preliminary test, the study was terminated. The experiment with the concentration of 100 mg/l included in the preliminary test has been performed using 20 daphnia, there through the conditions of the limit testgiven in guidelinehave been fulfilled. It was demonstrated that the EC50 is higher than this concentration.

The study was performed without analytical determination of the test substance concentrations. The test substance concentration control was performed by TOC method.

The concentrations of Total Organic Carbon (TOC) in the lowest and in the highest tested concentration were analysed in the preliminary test. Samples for determination of the TOC concentrations were taken at the beginning and at the end of the test. The nominal concentrations were used for all evaluation and results. The EC50 value, in a 48 hours observation period, was greater than 100 mg/l.
