Description of key information
Key value for chemical safety assessment
Additional information
There are no data on sediment toxicity. A PNEC can be estimated based on the equilibrium partitioning method.
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 hazardous according to Regulation (EC) No 1272/2008 or is assessed to be a PBT or vPvB. The hazard assessment of AA reveals that it is no 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
