Description of key information

According to Annex X of REACH (section 9.5.1. Long-term toxicity to sediment organisms),long-term testing shall be proposed by the registrant if the results of the chemical safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. The choice of the appropriate test(s) depends on the results of the chemical safety assessment. No reliable data on toxicity of barium in the sediment compartment were identified. Therefore a PNECsediment will be determined using the equilibrium partitioning method based on the PNEC for the aquatic compartment.
