The product obtained by acid leaching of copper speiss. Composed primarily of antimony, arsenic and lead with high precious metal content.
study provides a conservative estimate of the EC50 (for crustacea),
derived on basis of the Classification outcome (Mixture toxicity rules)
from the worst case typical elemental compositions across the industry
as defined in IUCLID section 1.2 and 1.4).
result is applicable to all intermediates that fall under the defined
concentration ranges (IUCLID section 1.2).
of the model used:
Adequacy of prediction: the substance falls within the
applicability domain described above and, therefore, the predicted value
can be considered as reliable. The prediction is moreover conservative
as the highest release rates obtained for the T/D at pH6 were used as a
translator across the industry. Same conclusions apply to the prediction
of the Aquatic toxicity value.
