Materials and methods
- Principles of method if other than guideline:
- Aquatic toxicity of the UVCB substance was determined by classifying based on mixture rules from EU CLP (Tier 1: summation of classified components or Tier 2: additivity of soluble components to derive Hazard class) and back calculation to the corresponding EC10/NOEC range.

According to MeClas, the substance is classified as Aq.Chronic Cat.2 to the environment.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Good quality estimate of the EC10/NOEC of the UVCB substance.
The substance is classified as Aq. Chronic Cat.2 to the environment resulting in a EC10/NOEC <= 1 mg/L. - Executive summary:
The study provided a conservative estimate of the effect concentration, derived on basis of the classification outcome (mixture toxicity rules) from a reasonable worst-case sample of the substance using mineralogical information from the representative sample.
Validity of the model used:
1. Defined endpoint: The endpoint is a REACH compliant defined endpoint
2. Unambiguous algorithm: EU CLP guidance based summation formula to determine classification, followed by back-calculation to related hazard criteria
3. Applicability domain: Applicable to classify complex metal containing materials
4. Mechanistic interpretation - metal species: The tool translates the elemental composition into a mineralogical composition relevant for classification
