Description of key information

Dibutylether was not readily biodegradable in OECD 301 series tests.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Limited biodegradation of dibutylether (<5% in 28 days) was observed in OECD 301 ready biodegradation tests. Tests conducted with enrichment cultures of bacteria isolated from activated sludge demonstrated that the bacteria could use dibutylether as a sole carbon source during biodegradation. No biodegradation was observed under anaerobic conditions in samples of groundwater and sediments.
