Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- A defined amount of substance was spiked to a vessel with sediment and water, and aliquots of both phases were analyzed after workup. The amounts of substance quantified in water and sediment extract were summed up and divided by the amount of substance initially spiked into the experiment vessel to determine the recovery rate, which should decrease over the course of the experiment if a degradation of the substance takes place.

Results and discussion
Any other information on results incl. tables
Recovery
rates for Tehyltriphenylphosphonium bromide remained constant at about
70–80%, which indicates that it was not degraded, but rather persistent
under test conditions (loss in the mass balance probably due to the
formation of non-extractable residues). Additionally, concentrations
found in the sediment extracts were significantly higher than in the
water phase.
Applicant's summary and conclusion
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.
