Description of key information
In the assessment of diammonium hydrogen citrate, read-across to the assessment entities ammonium and citrate is applied since these dissociation products determine the fate and toxicity of diammonium hydrogen citrate in the environment.
Ammonium is an important nitrogen source for algae, cyanobacteria and macrophytes and with a 5d-EC50 of 1,300 mg/L (Chlorella vulgaris) of low potential toxicity. Also, citrate in the form of citric acid is of low potential toxicity with a7d-EC50 of 640 mg/L for freshwater algae Scenedesmus subspicatus under neutralised conditions and 7d-EC50 > 100 mg/L (graphical estimation) for four different saltwater algae species under non-neutralised conditions, respectively.Thus, diammonium hydrogen citrate has a low potential for toxicity to aquatic algae and cyanobacteria.
Key value for chemical safety assessment
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.
