Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Accumulation in aquatic organisms is not to be expected
Key value for chemical safety assessment
Additional information
Based on the high water solubility and the ionic nature of ammonium sulphate, potassium sulfate and sodium sulphate, accumulation in organisms is not to be expected.
Ammonium sulphate, potassium sulfate and sodium sulphate are all highly soluble inorganic substances that will exist in a dissociated form in aqueous solution. Bioaccumulation of the dissociated ions is not expected. This assumption is supported by a calculated BCF available for sodium sulphate of 0.5. Furthermore the uptake and intra- and extracellular concentrations of the essential elements nitrate, sodium and potassium actively regulated by organisms.
