Key value for chemical safety assessment
Additional information
In analogy to the NTA acid the long-term toxicity to fish was investigated with the salt Na3NTA.
Arthur et al. (1974) reports a 228 d NOEC of > 54 mg/L for survival and reproduction for the fathead minnow, Pimephales promelas. The study was performed by exposing 3 -15 day old fry. Mortality, spawing activity and hatchability were assessed. Additionally a flow through study with larvae of several fish species is available [Birge, 1979]. The lowest effect values were determined for Oncorhynchus mykiss with a 27 d LC50 of 90.5 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.
