Description of key information

The ready biodegradability of test substance dihydronepetalactone was determined during a GLP-compliant study performed in accordance with OECD Test Guideline 301F (Manometric Respirometry).


Sodium benzoate was used as a reference substance and the activated sludge was taken from a domestic sewage treatment plant.  Oxygen consumption was evaluated on Day 0, 7, 14, 21 and 28.  All validation criteria were met.


On Day 14 (10-day window) the test substance did not achieve the 60% of the ThOD and therefore dihydronepetalactone was not readily biodegradable.  The obtained biodegradation value of 71% indicates that dihydronepetalactone is inherently biodegradable.
