Materials and methods

Principles of method if other than guideline:
Acute (dermal) toxicity of the UVCB substance was determined by classifying based on Mixture rules from EU CLP (summation and/or additivity of classified components to derive Hazard class) and back calculation to the corresponding Acute (oral) Toxicity criteria
GLP compliance:
(equivalent Quality assurance)
Test type:
other: CLP calculation software

Test material

Constituent 1
Reference substance name:
sulfuric acid hydrate
EC Number:
sulfuric acid hydrate
Details on test material:
Worst case (maximum across industry) as in iu 1.2;
See IUCLID Section 1.4, for company specific elemental composition; and representative sample for mineralogical information (IUCLID Section 4.23 -Outotec report)

other: prediction

Any other information on results incl. tables

 The calculated classification via Additivity method (lower Tier Arche CLP Tool) resulted in a Classification "Acute (dermal): not classified" for the UVCB substance Copper Slime (toxicity of all metal constituents > 1% w/w is known, from 1st ATP CLP + all assessed metals).

Based on this result, the related criteria provided the estimated value for acute (dermal) toxicity: Acute Toxicity Estimate >2000 mg/kg bodyweight.

Applicant's summary and conclusion

Interpretation of results:
not classified
Migrated information Criteria used for interpretation of results: other: EU CLP mixture toxicity rules
Good quality study that can be used to predict a ATE of the UVCB substance. Note: toxicities of constituents/species as of 1st ATP CLP + assessed metals
Executive summary:

The study provided an estimate of the Acute (dermal) toxicity, derived on basis of the Classification outcome (Mixture toxicity rules, no acute dermal toxicity = no dermal toxicity) from the UVCB (max across industry) as defined in IUCLID section 1.2/1.4/4.23. The result is applicable to all sulfuric acid, waste gas cooling and cleaning, copper smelting that fall under the defined concentration ranges (IUCLID section 1.2).
