The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Two studies are available from the migrated NONS file provided by ECHA. One shows a 48h EC50 of 19.1 mg/L. The other shows the 24h EC50 to be 34.15 mg/L and the 48h EC50 to be 12.17 mg/L. The 48h NOEC was found to be 6.25 mg/L. The 48h test is the guideline study duration and therefore the worst case value of 12.17 mg/L is taken as the endpoint.
