Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Biodegradation in water and sediment: simulation tests

Description of key information
This study was not conducted since it is scientifically unjustified.
Key value for chemical safety assessment
Additional information
Various screening studies have shown that biodegradation of DTPA occurs very slowly under typical environmental conditions. Thus, little useful information would be gained from a simulation study in water and sediment. Photodegradation of DTPA, particularly the iron (Fe+3) chelate, is expected to be a major degradation route in the aqueous environment. Photodegradation studies have identified the following photodegradation products for DTPA: Diethylenetriaminetetraacetic acid, diethylenetriaminetriacetic acid, ethylenediaminetriacetic acid, N,N'- and/or N,N-ethylenediaminediacetic acid, iminodiacetate, ethylenediaminemonoacetic acid and glycine.
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.
