Description of key information
According to REACH regulation Annex XI, a study is scientifically unjustified. Based on the Guidance Document R.7b (ECHA, 2008), substances that are potentially capable of depositing on or sorbing to sediments to a significant extent have to be assessed for toxicity to sediment-dwelling organisms. The main property of a substance that triggers the assessment for the sediment compartment is the potential to adsorb or bind onto sediment, proposing a logKow of 3 as cut off value. With a logKow of -0.16, hydrazine has only a low potential to sorb on soil or sediment excluding the deposition on or sorption to sediments to a significant extent. Concluding, in the absence of a relevant exposure, the toxicity of hydrazine towards sediment-dwelling organisms does not need to be assessed.

Additional information
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.
