Key value for chemical safety assessment

Additional information

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 assessment results in Risk Characterisation Ratios below 1 for sediment dwelling fresh water organisms, no studies on the chronic toxicity in sediment dwelling organisms are provided.

There are no data available concerning toxic effects of DMD to sediment organisms. Therefore, PNECsediment will be derived by use of PNECaqua and equilibrium partitioning method.
