The purpose of this assay was to identify the aquatic toxicity potential
of the test material in Daphnia magna to provide a rational basis for
hazard estimation for the test item in aquatic environments.
For this purpose, juvenile Daphnia magna were exposed to an aqueous test
material preparation over 48 hours, under defined conditions. The GLP
study was performed as a limit test according to OECD TG 202.
The follwing results have been obtained:
Nominal concentration Immobilization immobilized / exposed
Daphnia magna exposed to an aqueous preparation of the
nominal concentration of 100 mg per L of test item were not affected.
For the test material the following EC50 values for Daphnia
magna were determined:
24 h EC50 > 0,1 g/L (nominal > 100 mg/L)
48 h EC50 > 0,1 g/L (nominal > 100 mg/L)
NOEC > 0.1 g/L (nominal)
LOEC > 0.1 g/L (nominal)
Under the given experimental conditions, the test material showed no
aquatic toxicity. The 48 hours NOEC to Daphnia magna is > 100 mg/L.
For this endpoint, adequate information is provided from a GLP compliant
OECD TG 202 study, giving a NOEC of > 100 mg/L (nominal).
NOEC > 100 mg/L (nominal)
