Description of key information

In Annex IX of Regulation (EC) No 1907/2006, it is laid down that long-term toxicity testing shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on sediment organisms.
According to Annex I of this regulation, the chemical safety assessment triggers further action when the substance or the preparation meets the criteria for classification as dangerous according to Directive 67/548/EEC or Directive 1999/45/EC or is assessed to be a PBT or vPvB.
The hazard assessment of BA reveals neither a need to classify the substance as dangerous for the environment, nor is it a PBT or vPvB substance. Furthermore, due to the physico-chemical properties of the substance and its ready biodegradability, a considerable exposure of the sediment compartment is unlikely.
Therefore, a long-term toxicity study in sediment organisms is not provided. The PNEC sediment can be estimated based on the equilibrium partitioning method.
