Conclusion on environmental classification

The poorly soluble substance titanium, iron and aluminium pseudobrookite 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 aluminium (1,040 µg Al/L at pH 6 and 3,390 µg Al/L at pH 8), iron (>100 mg Fe/L) and titanium are above 1 mg/L and 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 of aluminium, iron and titanium ions and the fact that almost all dissolved metal concentrations, except the dissolved iron concentration at pH 6 (1.34 µg Fe/L), remained below the respective LODs (< 0.161 µg Al/L, < 0.035 µg Fe/L) or LOQs (< 0.123 µg Ti/L) after 7 days T/D tests at pH 6 and 8, it can be concluded that the substance titanium, iron and aluminium pseudobrookite 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, a chronic ERV for dissolved aluminium ions has not been derived since a concern for long-term (chronic) toxicity of aluminium ions was not identified (no classification), according to the Classification and Labelling Committee in 1999 (see report 013-003-00-7 submitted to the C&L Committee, 1999). The chronic ERVs of 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.” Due to the lack of a chronic aquatic hazard potential of aluminium, iron and titanium ions and the fact that 28 days T/D tests at a loading of 1 mg/L at pH 6 and 8, resulted in maximum quantified metal concentrations of 0.533 µg Al/L (at pH 8), 0.357 µg Fe/L (at pH 6) and 0.063 µg Ti/L (at pH 6), while concentrations at the alternate pH remained below the LOD or LOQ, it can be concluded that the substance titanium, iron and aluminium pseudobrookite 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 titanium, iron and aluminium pseudobrookite 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 titanium, iron and aluminium pseudobrookite 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.
