Description of key information

Based on read across hexadecene is considered to be readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

A biodegradation study with hexadecene is not available. In the absence of data results have been read across from hexadec-1 -ene.

Battersby (1995) investigated the biodegradability of hexadec-1-ene in an OECD 301D closed bottle test. The validity criteria of the test were met, and hexadec-1 -ene was shown to meet the criteria for ready biodegradability.

MITI (1989) report the results of an OECD 301C test with hexadec-1-ene. Biodegradation after 28 days was reported based on BOD and analysed concentrations as 55 - 77% and 81 - 95% respectively. Douglas and Halls (1993) also investigated the biodegradability of hexadec-1-ene in an OECD 301D test. Biodegradation of hexadec-1-ene reached a maximum of 31% after 28 days.

On the basis of the results of the ready biodegradation screening test conducted by Battersby (1995) hexadecene is considered to be readily biodegradable.
