Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Secondary poisoning is not expected
Key value for chemical safety assessment
Additional information
Secondary poisoning in birds through exposure via earthworms or fish food chains is unlikely.
Phosphoric acid, potassium salt (2:3) dihydrate is highly soluble and dissociates immediately in water, with PO4-3and K+ions as main products. Both phosphates and potassium are considered essential nutrients for aquatic and terrestrial organisms, which possess internal mechanisms to regulate them. Therefore, the bioaccumulation and biomagnification of this substance through the food chain and consequent secondary poisoning is unlikely to occur and testing the effects of the substance in birds is not deemed necessary.
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.
