Additional information
PNEC aqua (freshwater)
For the 3 trophic levels (fish, invertebrates (Daphnia) and algae), several studies on the short-term toxicity are available. Therefore, the lowest L(E)C50 fixed value observed from all conducted studies shall be used for the derivation of the PNEC. The lowest values mentioned correspond to the tests on fish (MAP: 96h-LC50 > 85.9 mg/L) and algae (DAP: 72h-EC50 > 97.1 mg/L). However, these values corresponds to the highest concentrations tested in the studies, and these concentrations did not induce any significant adverse effect. As a result, the E/LC50 values here observed were not “real precise values” obtained through calculation, but was deduced from the data to be superior to the highest tested concentration. It was thus concluded to use the lowest quantified L(E)C50 value which has been obtained on fish: 96h-LC50 = 1700 mg/L. An assessment factor of 1000 is used in accordance with the “Guidance on information requirements and chemical safety assessment, Chapter R.10”.
PNEC aqua (freshwater): 1.7 mg/L
PNEC aqua (marine water)
The reasoning is the same as for PNEC aqua (freshwater) except that an assessment factor of 10000 is applied instead of 1000 in accordance with the “Guidance on information requirements and chemical safety assessment, Chapter R.10”.
PNEC aqua (marine water): 0.17mg/L
PNEC (intermittent releases)
The reasoning is the same as for PNEC aqua (freshwater) except that an assessment factor of 100 is applied instead of 1000 in accordance with the “Guidance on information requirements and chemical safety assessment, Chapter R.10”.
PNEC (intermittent releases): 17.0 mg/L
Conclusion on classification
As the reaction mass of ammonium dihydrogenorthophosphate and diammonium hydrogenorthophosphate is an inorganic substance, no PBT assessment has to be performed in accordance with Annex XIII.
As an inorganic substance, reaction mass of ammonium dihydrogenorthophosphate and diammonium hydrogenorthophosphate is not biodegradable. As simple inorganic salts with high aqueous solubility will exist in a dissociated form in an aqueous solution, such substances has a low potential for bioaccumulation. Short-term tests performed on the three trophic levels (i.e.fish, daphnids, algae) does not reveal any acute toxicity of the reaction mass and its constituents. As a result, reaction mass of ammonium dihydrogenorthophosphate and diammonium hydrogenorthophosphate is not classified regarding its environmental impacts, neither under the criteria of CLP, nor under those of DSD.
