Description of key information
Key value determined in experimental study performed to OECD Guideline 202, EU Method C2 and US EPA Procedure OCSPP 850.1010.
Key value for chemical safety assessment
Additional information
Under the conditions of this Daphnia magna acute immobilisation study the calculated and observed endpoints for the effect of CUCURBIT[8]URIL were the followings:
The 24h EC50 value: > 100 % saturated solution (nominal)
The 48h EC50 value: > 100 % saturated solution (nominal)
The 48h EC100 value: > 100 % saturated solution (nominal)
The 48h No-Observed Effect Concentration (NOEC):
> 100 % saturated solution (nominal)
The 48h Lowest Observed Effect Concentration (LOEC):
> 100 % saturated solution (nominal)
Based on the results of this study, the test item CUCURBIT[8]URIL had no toxic effect at saturation [36.02 mg/L Test Item, measured by NPOC (Non-Purgeable Organic Carbon) content]; the EC50 results and the LOEC are higher than the solubility level of the test item in the test medium.
