Description of key information
Additional information
A PNECsoil of 0.32mg/kg soil (dry weight) may be derived for an 80:20 mixture of 2,4- and 2,6-TDA from the lowest EC50 value of 320 mg/kg soil (dry weight) and an assessment factor of 1000. It may be expected that ortho-TDA will have a similar PNEC value.
2,4-TDA and 2,6 -TDA are structural isomers of o-TDA, differing in the substitution pattern of the amine groups on the tolyl ring; having similar physical chemical properties; similar environmental fate; and similar health effects (acute toxicity and genotoxicity). As a result, data from 2,4 and 2,6-TDA can be used for read across to ortho- TDA.
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.
