General Information
- Name:
- Cobalt magnesium tin spinel
- Not classified
- Implementation:
- EU
- Type of classification:
- self-classification
- Remarks:
Conclusion on environmental classification
The poorly soluble substance Cobalt magnesium tin spinel is evaluated by comparing the dissolved metal ion levels resulting from the transformation/dissolution test after 7 and 28 days at a loading rate of 1 mg/L with the lowest acute and chronic ecotoxicity reference values (ERVs) as determined for the (soluble) metal ions. The acute and chronic ERVs are based on the lowest EC50/LC50 and NOEC/EC10 values for algae, invertebrates, and fish, respectively. Acute and chronic ERVs were obtained from the Metals Classification tool (MeClas) database as follows:
The acute ERV for cobalt is 52 µg Co/L, and thus well above the dissolved cobalt concentrations of 0.412 µg Co/L at pH 6 and 0.677 µg Co/L at pH 8, determined after 7 days T/D tests at a loading of 1 mg/L. The acute ERVs of magnesium and tin ions are above 1 mg/L and thus a concern for short-term (acute) toxicity was not identified (no classification). According to ECHA Guidance on the Application of the CLP Criteria (Version 5.0, July 2017), “Where the acute ERV for the metal ions of concern is greater than 1 mg/L the metals need not be considered further in the classification scheme for acute hazard.”
Due to the lack of an acute aquatic hazard potential for soluble magnesium and tin ions and the fact that dissolved cobalt concentrations after 7 days T/D tests at a loading of 1 mg/L and pH 6 and 8 were significantly lower than the lowest acute ERV for cobalt, it can be concluded that the substance Cobalt magnesium tin spinel is not sufficiently soluble to cause short-term toxicity at the level of the acute ERVs (expressed as EC50/LC50).
Regarding the long-term toxicity, the chronic ERV for cobalt is 7.6 μg Co/L and thus well above the dissolved cobalt concentrations of 0.498 µg Co/L at pH 6 and 0.764 µg Co/L at pH 8, determined after 28 days T/D tests at a loading of 1 mg/L. The chronic ERVs of magnesium and tin ions are above 1 mg/L, and a concern for long-term (chronic) toxicity was not identified (no classification). According to ECHA Guidance on the Application of the CLP Criteria (Version 5.0, July 2017), ”Where the chronic ERV for the metal ions of concern corrected for the molecular weight of the compound (further called as chronic ERV compound) is greater than 1 mg/L, the metal compounds need not to be considered further in the classification scheme for long-term hazard.”
Due to the lack of a chronic aquatic hazard potential for magnesium and tin ions and the fact that dissolved cobalt concentrations after 28 days T/D tests at a loading of 1 mg/L and pH 6 and 8 were below the lowest chronic ERV for cobalt, it can be concluded that the substance Cobalt magnesium tin spinel is not sufficiently soluble to cause long-term toxicity at the level of the chronic ERVs (expressed as NOEC/EC10).
In accordance with Figure IV.4 “Classification strategy for determining acute aquatic hazard for metal compounds” and Figure IV.5 „Classification strategy for determining long-term aquatic hazard for metal compounds “of ECHA Guidance on the Application of the CLP Criteria (Version 5.0, July 2017) and section 4.1.2.10.2. of Regulation (EC) No 1272/2008, the substance Cobalt magnesium tin spinel is poorly soluble and does not meet classification criteria for acute (short-term) and chronic (long-term) aquatic hazard.
In sum, the substance Cobalt magnesium tin spinel is poorly soluble and does not meet classification criteria of Regulation (EC) No 1272/2008 for acute (short-term) and chronic (long-term) aquatic hazard.
