EC number: 236-813-4 | CAS number: 13494-80-9
Long-term toxicity to aquatic invertebrates
Administrative data
- Endpoint:
- long-term toxicity to aquatic invertebrates
- Type of information:
- experimental study planned (based on read-across)
- Justification for type of information:
- Elemental tellurium and tellurium dioxide are relatively poorly water soluble. Underlying the basic assumption that
effects caused by the bioavailable metal fraction and the same toxicokinetic behaviour, ecotoxicity data from
higher soluble tellurium compound were considered appropriate for the ecotoxicity assessment of tellurium.
Sodium tellurate (Na2TeO4; CAS: 10101-83-4) is known to be readily soluble in water, it is therefore considered
as an adequate testing material for OECD 211 and for read-across to tellurium metal and tellurium dioxide.
