Administrative data

Endpoint:
activated sludge respiration inhibition testing
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water, hence indicating that aquatic toxicity is unlikely to occur
other:
Justification for type of information:
Data on the substance toxicity to STP microorganisms is driven by the assessment of the individual transformed UVCB constituents (assessment entity approach). The following relevant information is reported in the IUCLID summaries of Section 6:

PNEC STP for Ni: 0.33 mg Mi/L
PNEC STP for Co: 0.37 mg Co/L
