Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Reliable information on the toxicity of the submission substance to fish, daphnia, algae and sewage sludge is available.

As the submission substance consists of two constituents (1.) a complex of Ca phosphate with potassium humate and 2.) Ca sulfate) data on these components are used to assess the aquatic toxicity for these substances (for justification of the read-across approach see Chapter 1 of the Chemical Safety Report and the Read-across Justification document).

On this basis the following key values for the various aquatic species were established:

LC50 (fish): >86 mg/L

LC50 (daphnia): >100 mg/L

ErC50 (algae): >88 mg/L

EC50 (microorganisms): >100 mg/L
