Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The biodegradation of DTPA was assessed in several screening tests.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
In standard biodegradation screening tests, including several ready biodegradation tests, no detectable biodegradation of DTPA was observed. In several studies, increasing the sludge age or increasing the pH of the test system resulted in some degradation of the DTPA. Pre-treatment of wastewaters containing DTPA using various oxidation processes can result in degradation of the compound.
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.
