Conclusion on classification

The poorly soluble substance chromium, iron, titanium and zinc spinel and rutile 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 or NOEC/EC10 values for algae, invertebrates and fish, respectively, and were obtained from the Metals classification tool (MeClas) database as follows:


The acute ERVs of trivalent chromium (> 100 mg Cr/L), iron (> 100 mg Fe/L) and titanium 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.” The acute ERVs for zinc are 413 µg Zn/L at pH 6-7 and 136 µg Zn/L at pH >7 and thus well above the respective dissolved zinc concentrations of 0.929 µg Zn/L at pH 6 and 3.68 µg Zn/L at pH 8 obtained after 7 days T/D tests at a loading of 1 mg/L. Due to the lack of an acute aquatic hazard potential for soluble trivalent chromium, iron and titanium ions and the fact that dissolved zinc concentrations after 7 days T/D tests at a loading of 1 mg/L and pH 6 and 8 remained well below the respective lowest acute ERVs, it can be concluded that the substance chromium, iron, titanium and zinc spinel and rutile 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 ERVs for trivalent chromium, iron and titanium, 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.” The chronic ERVs for zinc are 82 µg Zn/L at pH 6-7 and 19 µg Zn/L at pH >7 and thus well above the respective dissolved zinc concentrations of 3.52 µg Zn/L at pH 6 and 4.78 µg Zn/L at pH 8 determined after 28 days T/D tests at a loading of 1 mg/L. Due to the lack of a chronic aquatic hazard potential of chromium, iron and titanium and the fact that dissolved zinc concentrations after 28 days T/D tests at a loading of 1 mg/L and pH 6 and 8 remained well below the respective lowest chronic ERVs, it can be concluded that the substance chromium, iron, titanium and zinc spinel and rutile 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 chromium, iron, titanium and zinc spinel and rutile is poorly soluble and does not meet classification criteria for acute (short-term) and chronic (long-term) aquatic hazard.


 


In sum, the substance chromium, iron, titanium and zinc spinel and rutile 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.
