study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because a long-term aquatic toxicity study on invertebrates is available

Description of key information

Exposure of Daphnia magna to the test item resulted in significant mortalities at the test concentration of 1.5 mg/L resulting in 100% mortalities by Day 5.

The 21-Day EC50 (immobilization) value, based geometric mean measured concentrations, for the parental daphnia generation (P1) was calculated to be 1.0 mg/L. Due to the nature of the data, no confidence limits could be determined.

The 21-Day EC50 (reproduction) based on geometric mean measured concentrations was 0.56 mg/L. Due to the nature of the data, no confidence limits could be determined.

The "Lowest Observed Effect Concentration" (LOEC) and the "No Observed Effect Concentration" (NOEC) based on geometric mean measured concentrations were 0.52 and 0.15 mg/L respectively.

The Chronic Value (ChV) was determined to be 0.28 mg/L.
