Administrative data

Endpoint:
toxicity to non-target arthropods on natural substrate (NTA other than pollinators)
Data waiving:
exposure considerations
Justification for data waiving:
the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely
Justification for type of information:
The UVCB itself is highly insoluble in water. Data on the substance toxicity to terrestrial organisms (soil macro-organisms except arthropods) is driven by the assessment of the individual transformed UVCB constituents (assessment entity approach). The following relevant information is also reported in the IUCLID summary, Section 6:

PNECsoil for Ni: 29.9 mg Ni/kg dw.
PNECsoil for Co: 10.9 mg Co/kg dw.
