Description of key information

The substance is acutely not harmful to freshwater fish.

Key value for chemical safety assessment

Additional information

As the substance is a salt of phosphate, effects can be read-across from the cation, which is likely to have the more important effects. In biological systems, phosphate is an abundant in cells and body fluids. In ecological terms, because of its important role in biological systems, phosphate is a highly sought-after resource. Thus, read-across from component CAS Reg.-No. 108-78-1, melamine, is justified. All effect values are minimum values as the molar ratio anion:cation equals 1.74.

The results of the studies are summarized in the table below. The studies revealed LC50 values clearly above the regulatorily relevant threshold of 100 mg/L. Thus it can be stated that the compound is not acutely harmful to fish.
