Description of key information

The test substance is readily biodegradableaccording to OECD criteria.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The biodegradability of 2 -aminoethanol (CAS 141 -43 -5) was investigted in several ready biodegradability tests in an OECD ring test (BASF AG, 1995). According to the OECD criteria, 2 -aminoethanol is readily biodegradable; the 10 -d window was kept in all guideline studies.

Key study: BASF AG (1995). OECD 301A: > 90% DOC removal after 4 d

Supporting studies:

- BASF AG (1995). OECD 301B: > 60% CO2 after 5 d, > 80% after 19 d

- BASF AG (1995). OECD 301F: 60% BOD after 5 d, 70% after 14 d

- BASF AG (1995). OECD 301F: > 60% BOD after 5d, 75% BOD after 14 d

- MITI (1975). OECD 301C: 83% BOD after 14 d
