Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Since the substance is classified as chronic Cat. 3 for the environment, an assessment of the potential hazard of Reaction mass of ammonium diaqua[bis(oxalate)]oxoniobate(1-) hydrate and ammonium hydrogen oxalate oxalic acid (1:1:1) dehydrate to aquatic, sediment dwelling and terrestrial species was performed. The environmental exposure assessment (see CSR attached to IUCLID section 13) shows that the Risk Characterization Ratio (i. e. PEC/PNEC ratio) in the aquatic, sediment and soil compartment is < 1 and therefore, under the current exposure conditions, Reaction mass of ammonium diaqua[bis(oxalate)]oxoniobate(1-) hydrate and ammonium hydrogen oxalate oxalic acid (1:1:1) dehydrate does not pose a risk to the environment.

Conclusion on classification

Conclusion on Classification

Biodegradation: 99 % after 28 d (OECD 301C, organic moiety)

Bioaccumulation: BCF < 23 (Cyprinus carpio, OECD 305, nominal)

 

Aquatic acute toxicity

Fish: 96 h, LC50 (Oncorhynchus mykiss): > 100 mg/L (nominal; OECD 203)

Aquatic invertebrates: 48 h, EC50 (Daphnia magna): > 34 mg/L (measured; OECD 202)

Aquatic algae: 72 h, EC50 (P. subcapitata): 21.1 mg/L (measured; OECD 201)

 

Aquatic chronic toxicity

Fish: no data

Aquatic invertebrates: no data

Aquatic algae: 72 h, NOEC (P. subcapitata): 0.352 mg/L (measured; OECD 201)

 

Classification according to CLP

Based on the data above, Reaction mass of ammonium diaqua[bis(oxalate)]oxoniobate(1-) hydrate and ammonium hydrogen oxalate oxalic acid (1:1:1) dehydrate needs to be classified and labelled as environmental hazard Chronic Cat. 3 according to Regulation (EC) No. 1272/2008 (CLP) and further amendments based on the NOErC (72h) of 0.352 mg/L for algae.
