Description of key information
Accumulation of NTA acid in organisms is not to be expected.
Key value for chemical safety assessment
Additional information
In accordance with column 2 of REACH Annex IX, the bioaccumulation in aquatic species study does not need to be conducted as the substance has a low potential for bioaccumulation (the substance has a log octanol water partition coefficient less than 3).
However, the EU RAR 2005 cites results of a study conducted by Lentz and Lidzba (1988) for the analog salt Na3NTA, determining the bioaccumulation by a series of species (fish, snail, backswimmer, worm, frog, and crayfish).The study demonstrates that only a low accumulation of NTA occurs in the hydrosphere (BCF values around 3-20 L/kg.
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.
