Description of key information
The test substance is readily biodegradable according to OECD criteria.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The biodegradability of 2 -aminoethanol (MEA, CAS 141-43-5) was investigated in several ready biodegradability tests in an OECD ring test (BASF AG, 1995) using non-adapted, domestic activated sludge as inoculum. 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 , > 90% DOC after 21 d
Supporting studies:
- BASF AG (1995). OECD 301B: > 60% CO2 after 5 d, > 80% after 31 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
- Emtiazi & Knapp (1994). Die-away test. River water, 100% after 1.5 d.
Additionally, two guideline studies according to OECD 306 were performed with saltwater by Eide-Haugmo et al. (2009/2012). In the study from 2009 the BOD was < 40% after 28 days. In the study from 2012 the BOD was 68% after 28 days.
Therefore, MEA is readily biodegradable according to OECD criteria.
