Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Short-term toxicity to fish
Administrative data
Link to relevant study record(s)
Description of key information
Two reliable short-term tests are available. The studies were performed with a freshwater and a marine species under flow-through conditions. The reported 96-hour LC50 values are in the range of 38 and 60 mg ATBC/L, based on nominal test substance concentrations. The data indicate that there is a comparable sensitivity of freshwater and marine fish.

Additional information
Two reliable short-term tests are available. The studies were performed with freshwater and marine species under flow-through conditions. The lowest LC50 value was determined
The reported 96-hour LC50 values are in the range of 38 and 60 mg ATBC/L, based on nominal test substance concentrations. The test concentrations were chemically analysed. However, the recovery of the test substance was unsatisfactory and nominal concentrations were used for the evaluation. The data indicate that there is a comparable sensitivity of freshwater and marine fish.
The information was taken from summary reports published by the U.S. EPA High Production Volume (HPV) Chemicals Challenge Program 2003.
The lower value of the LC50 range obtained in the fish studies was considered most relevant for the aquatic hazard assessment:
96 h LC50 Lepomis machrochirus 38 mg/L.
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.
