Key value for chemical safety assessment

Additional information

The test substance is not supposed to be directly applied to sediment. According to the Mackay Level I distribution modeling the test item will predominantly be distributed in the compartment water. Additionally, according to Annex X long-term toxicity tests for sediment organisms shall be proposed if the result of the Chemical Safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. Since the Risk Characterisation Ratio of the risk assessment is below 1 for the sediment compartment, no studies are provided.
