delta-Valerolacton is readily biodegradable (according to OECD criteria).
For the assessment of biodegradability a non-GLP test according to OECd
guideline 301E was identified. As inoculum, non-adapted domestic
activated sludge from a laboratory scale STP was used. After 8 days the
test substance was degraded at an amount of 80 -90% related to the DOC
elimination (BASF 1990).
