Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
With high probability acute not harmful to aquatic invertebrates
Key value for chemical safety assessment
Additional information
Studies on the acute toxicity of the reaction mass of ammonium sulphate and potassium sulfate and sodium sulphate to aquatic invertebrates are not available. The presented data refer to studies conducted with the single components ammonium sulphate, potassium sulfate and sodium sulphate respectively. The available data indicate that the single substances are not harmful to aquatic invertebrates. For ammonium sulphate a LC50 > 100 mg/L was determined for Daphnia magna in a multi species test. The crustaceans were exposed to the substance in a flow-through test for 96 hours. The toxicity of sodium sulphate and potassium sulfate was tested in two guideline studies following EPA/600/4-90/027 (1991). Daphnia magna were exposed to the substances for 48 hours in static test systems. For sodium sulphate an EC50 of 4580 mg/L was determined. The EC50 detected for potassium sulfate was 720 mg/L. Both results refer to the measured concentrations (Mount et al., 1997; cited in OECD SIDS, 2005/2007).
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.
