Description of key information

The ready biodegradability of 2-aminobutanol was determined in and OECD 301F Manometric Respirometry test.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

2-Aminobutanol meets the criteria for ready biodegradability based on the OECD 301F test. At the end of the 28-day test, the extent of biodegradation based on BOD, CO2 evolution, and dissolved organic carbon (DOC) removal for 11 mg/L test substance reached 119 ± 5.0%, 93.0 ± 11.8%, and 85.0 ± 21.3% (mean ± 1 Std. Dev). No biodegradation was observed in an OECD 301F test using 100 mg/L test substance in which the oxygen consumption measured in the test mixtures was less than the control mixtures (no test substance added). These results suggest that the test substance may be inhibitory to the microbial inoculum at high test concentrations.
