Additional information

The biodegradation of n-Butyl vinyl ether was tested in a CO2 Test in seasled vessels (Headspace Test) according to OECD Test Guideline 310. The degree of biodegradation after an exposure period of 28 days was 83±1 % TIC/TOC in this test. The mean value of degree of biodegradation was calculated by the single values of five test assays at the end of exposure with a limit of confidence of 95 %. The required pass level of the ten day window for ready biodegradability was reached. Thus n-Butyl vinyl ether is considered as readily biodegradable.
