EC number: 839-353-8 | CAS number: -
Toxicity to soil microorganisms
Administrative data
- Endpoint:
- toxicity to soil microorganisms
- 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 micro-organisms) 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.
