Long-term toxicity to aquatic invertebrates

Description of key information
In accordance with REACH Annex XI, section 1.5 (Grouping of substances and read-across approach) the long-term toxicity test on invertebrates does not need to be conducted as nitric acid will dissociate into H+ ions (resulting in a pH decrease) and nitrate ions, and studies done on nitric acid can subsequently be used to support the low long-term aquatic toxicity of nitrate. Furthermore, long-term effects to daphnia at environmentally relevant pH values are not expected to occur (Belanger and Cherry, 1990).
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.
