Conclusion on classification
Relevant key information
Fish: No mortality at the loading rate of 100 mg/L during 96 h exposure was observed; LC50 (96 h) > 100 mg/L (nominal loading of the test material)
Crustacea (Daphnia magna): No immobility at the loading rate of 500 mg/L during 24 h exposure was observed; EC50 (24 h) > 500 mg/L (nominal loading of the test material); NOEC (21 d, reproduction): 0.142 mg/L (measured concentration).
Algae (P. subcapitata): EC50 (72 h) = 9.7 mg/L (nominal loading of the test material); NOEC (72 h) = 8 mg/L (nominal loading of the test material)
Classification according to Regulation (EC) No 1272/2008 (CLP) considering the 2nd ATP (Regulation (EU) No 286/2011)
Acute Hazards
However, as a pigment, the substance exhibited an intensive blue color in the test solutions, increasing with the loading rate of the test material, which could have resulted in a loading dependent impact on the light service during the exposure. Furthermore, the test was performed using EDTA contained test medium and a polar organic vehicle (2-methoxyethanol) was used in the test, which had significant effect on the solubility behavior of the test material. Therefore, the test result is considered as of no relevance for the evaluation of the acute aquatic toxicity. Because of the substance related limitation on the reliability of algae test, the acute ecotoxicity reference value of the test substance is driven by the fish and daphnia data as > 1 mg/L andno acute aquatic classificationneeds to assigned for ammonium iron(3+) hexakis(cyano-C)ferrate(4-).
Chronic Hazards
The test was performed using EDTA free dilution water and no application of a solvent. Due to absence of a test following the transformation/dissolution (T/D) protocol, there is no reliable information available on evidence of rapid environmental transformation. With the reference of the analytical monitoring data on the determination of iron concentration (renewal of test solutions on day 4, 10 and 18), the iron concentrations in the older solutions ranged from 60 to 108% of that of new solution. Thus, no significant transformation was observed. In accordance with the Guidance on the Application of the CLP Criteria, version 4 (ECHA, 2013), Figure IV5.3-b (p. 617) and 5.3-c (p. 618), ammonium iron(3+) hexakis(cyano-C)ferrate(4-) needs to classified as Chronic Aquatic Hazard Category 4 (H413) based on the reasons below:
- No acute aquatic hazard classification
- Substance is not readily soluble (OECD 105)
- Chronic environmental reference value is < 1 mg/L
- No T/D test available
- Not rapidly transformed by normal environmental processes.
