Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
GLP compliance:
not specified
Remarks:
other quality assurance was applied

Results and discussion

Effect concentrations
Remarks on result:
not measured/tested
Details on results:
The substance is classified as aquatic chronic category 3

Any other information on results incl. tables

According to MeClas, the substance is classified as aquatic chronic 3 under CLP.

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The substance is classified as aquatic chronic category 3.
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
