Additional information

Biodegradation in water: screening tests

In accordance with Column 2 adaptation statement of REACH Annex VIII, hydrolysis as a function of pH, information requirement 9.2.2.1, does not need to be conducted if the test substance is inorganic in nature.

Biodegradation in water and sediment: simulation tests

In accordance with Column 2 adaptation statement of REACH Annex VIII, hydrolysis as a function of pH, information requirement 9.2.2.1, does not need to be conducted if the test substance is inorganic in nature. Moreover given its high water solubility the substance is expected to ionize giving Ca2+ and IO3-.

Biodegradation in soil

Since the substance is inorganic in nature, the study need not be conducted. Secondly, the half life period in case of soil is 1800 hrs and based on this information it can be concluded that the substance will have a lower biodegradation in soil environment as compared to the other environment (air, water and sediment). But, since the exposure to the soil compartment is unlikely so the persistence level of the substance in soil is not considered. Therefore this study was considered for waiver.
