Description of key information
With high probability acutely not harmful to fish.
Key value for chemical safety assessment
Additional information
In analogy to the NTA acid the acute toxicity to fish was investigated with the salt Na3NTA.
The effect of trisodium nitriloacetate on the fathead minnow (Pimephales promelas) was determined in an aerated, flow through test [Arthur, 1974]. The 96-hour LC50 based on measured concentrations was 114 mg/L. Additionally a static study with the same test species is available [Macek & Sturm, 1973]. The 96-hours LC50 (nominal) was determined to be 127 mg/L.
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.
