EC number: 689-732-5
CAS number: 956317-36-5
48-hour EC50 value was determined by empirical estimation to be >97 mg
a.i./L. Additional testing to further define the EC50 value was not
conducted as this would exceed OECD guideline (100mg/L). The
No-Observed-Effect Concentration (NOEC) was determined to be 97 mg/L.
The highest concentration producing 0% immobilization was 97 mg/L. The
lowest concentration producing 100% immobilization was > 97 mg/L.
In a GLP compliant guideline, the effect of the
test substance on Daphnia magna was determined. As no concentration
tested resulted in a ≥50% immobilization, the 48-hour EC50 value was
empirically estimated to be > 97 mg/L, the highest mean measured
concentration tested. Additional testing to further define the EC50
value was not conducted since the highest nominal treatment level tested
(100 mg/L) is the highest concentration required by the OECD guideline.
The No-Observed-Effect Concentration (NOEC) was
determined to be 97 mg/L. The limits of test substance concentration
producing 0% and 100% immobilisation are indicated. The highest
concentration producing 0% immobilization was 97 mg/L. The lowest
concentration producing 100% immobilization was > 97 mg/L.
