Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 two separate studies available for this end-point, one of which is for two separate species of fish, and the results of these are as follows:
LC50 (96 hr) Guppies & Harlequin fish: 250 – 500 ppm (Brown & Hubble 1969).
LC50 (96 hr) rainbow trout:164 mg/L (Thorpe 1978).
Both of the studies are considered a Reliability 2 and therefore the Thorpe study has been chosen as the Key Study as this has the lowest LC50, hence it can be considered as worst-case.
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.
