Dipotassium bis[μ-[tartrato(4-)-O1,O2:O3,O4]]diantimonate(2-) , stereoisomer

Biodegradation in water and sediment: simulation tests

Administrative data

Endpoint:

biodegradation in water: sediment simulation 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 readily biodegradable

the study does not need to be conducted because direct and indirect exposure of sediment is unlikely

Justification for type of information:

In accordance with Column 2 adaptation statement of REACH Annex IX, this study does not need to be conducted based on the high biodegradation of the substance.
