Key value for chemical safety assessment

Additional information

Based on the use pattern for this substance, direct and indirect exposure of sediment is unlikely. Level 3 fugacity modelling with a realistic split of mass flow inputs per compartment indicate that sediment concentrations would significantly lower than those of water (~30%) which would permit the extrapolation of toxicity data from the aquatic compartment to reasonably predict toxicity in sediment. In reality, concentrations would be less in sediment as the substance is readily biodegradable. On the basis that the substance is readility biodegradable and good aquatic toxicity information is available, no testing for sedimentary organism toxicity is therefore required.
