Description of key information

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 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.

In summary, the following properties of the compound could be derived:

  • There is a high probability that the product is not acutely harmful to fish.
  • There is a high probability that the product is not acutely harmful to aquatic invertebrates.
  • Based on long-term (chronic) toxicity study data, the product is very likely not harmful to aquatic invertebrates.
  • There is a high probability that the product is neither acutely nor chronically toxic to aquatic plants and cyanobacteria.
  • The inhibition of the degradation activity of activated sludge is not anticipated when introduced to biological treatment plants in appropriate low concentrations.
