Description of key information

Additional information

The substance 2,5-Xylenol is not readily biodegradable according to OECD criteria (2% after 28 d, OECD 301C). A study similar to OECD guideline 302B, conducted with adapted activated sludge as inoculum, determined a COD removal of 94.5% after 5 days. Based on the results the substance can be considered to be inherently biodegradable, not fulfilling specific criteria.
