Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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
There are several guideline studies available for freshwater fish. The studies are all static and the test concentrations are measured in most of the studies. The lowest observed effect concentration is a 96 -h LC50 value of 40613 mg/l in a study with Oncorhynchus mykiss (Beak Consultants Limited, 1995). The effect concentration determined in marine fish is a 96 -h LC50 of >10,000 mg/l in Scophthalmus maximus (Halliburton Energy Services, 2004). As higher values were not determined in this marine study, the effect concentration will not be used in the assessment. Only the value for the fresh water study will be used.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
