Description of key information

In the saturated solution with a nominal loading rate of 1.00 mL/L of the test substance, no effects on Daphnia magna were observed. The EL50 and the LOEL after 48 hours are >1.00 mL/L. The NOEL is >=1.00 mL/L based on the nominal loading rate of the test substance.

Key value for chemical safety assessment

Additional information

The acute toxicity on invertebrates has been examined in an guideline test according to OECD TG 202. A saturated solution with a nominal loading rate of 1.00 mL/L (corresponds to a initial nominal concentration of 0.946 g/L) has been tested, which has been generated by a slow-stirring procedure. The measured concentrations of the test substance have been below the limit of quantification (LOQ= 6 µg/L of the test substance) at the start (0 hours) and at the end of the exposure (48 hours). Therefore, the effect values are based on the nominal loading of the test item. In the saturated solution with a nominal loading rate of 1.00 mL/L of the test substance, no effects on Daphnia magna were observed.

The effect level EL10, EL50, EL100, and the LOEL after 48 hours are >1.00 mL/L. The NOEL is >=1.00 mL/L based on the nominal loading rate of the test substance. The water quality parameter were within acceptable limits and the validity criteria of the study has been fulfilled.
