Additional information

The toxicity to aquatic algae of the substance was assessed according to the OECD Guideline 201.

A non-GLP range finding test with nominal concentrations of 1, 10 and 100 mg/L of substance was performed. Only minimal effects were observed, therefore the definitive test was performed as a limit-test at the nominal concentration of 100 mg/L.

No significant effects were observed at 100 mg/L, as compared to the untreated controls. Based on the results of this study, the median effect concentration with respect to yield and growth rate EyC50(72h)/ErC50(72h) were estimated to be >100 mg/L.

The no observed effect concentration with respect to yield and growth rate was determined to be 100 mg/L nominal concentration.
