Description of key information

RCR freshwater < 1

Key value for chemical safety assessment

Additional information

In accordance with Regulation (EC) No 1907/2006, Column 2 of Annex IX, section 9.1.6 long-term toxicity tests on fish does not need to be investigated if the outcome of the chemical safety assessment shows no indication of risk on aquatic organisms from exposure to the substance in question. In a first step, the PNEC for the aquatic environment has been derived from tests on short-term toxicity using an appropriate assessment factor. The risk characterization ratio (RCR) has demonstrated that there is no indication of risk i.e. PEC/PNEC freshwater < 1 from current exposure conditions to Reaction mass of ammonium diaqua[bis(oxalate)]oxoniobate(1-) hydrate and ammonium hydrogen oxalate oxalic acid (1:1:1) dihydrate. In conclusion, in accordance to Regulation (EC) No. 1907/2006, Annex IX, Column 2, 9. 1, as the RCR freshwater is < 1 no further effects on aquatic organisms need to be investigated and a long-term test with fish is therefore not required.

Furthermore, acute toxicity tests on Reaction mass of ammonium diaqua[bis(oxalate)]oxoniobate(1-) hydrate and ammonium hydrogen oxalate oxalic acid (1:1:1) dihydrate revealed algae to be the most sensitive species.
