Description of key information

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.

Key value for chemical safety assessment

Half-life in soil:
1 800 h
at the temperature of:
25 °C
