Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
For Lepomis macrochirus an EC10 of 4.28 mg/L ammonium chloride was calculated after an exposure duration of 30 days.
Key value for chemical safety assessment
Fresh water fish

- Effect concentration:
- 4.28 mg/L
Additional information
For risk assessment of ammonium chloride the total topic of ammonia toxicity was regarded. Species mean chronic values (SMCV), as given by U.S. EPA (1999) were considered as relevant endpoints. The lowest species mean chronic value was calculated for Lepomis macrochirus EC20 = 1.35 mg N/L and EC10 = 1.12 mg N/L = 4.28 mg/L ammonium chloride (Smith et al. 1984, adjusted to pH 8 and 25 °C).
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.
