Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

biodegradation in water: sediment simulation testing
Data waiving:
study technically not feasible
Justification for data waiving:
Justification for type of information:
Degradation/biodegradation testing is not relevant for inorganic substances, like zinc selenite, which are considered as not (bio)degradable. Therefore, the chemical assessment of zinc selenite is based on the total initial Zn and Se concentrations, which can be considered as a worst-case assumption.
