An OECD 301F Manometric Respirometry test was conducted using C6-C7, n-alkanes, isoalkanes, cyclics C6 aliphatics, which is read across to isohexane. The test substance was 98% degraded at the end of 28 days, and 83% degraded at the end of the 10 -day window. The substance is therefore considered to be readily biodegradable
A OECD 301F Manometric Respirometry test was
conducted using C6-C7, n-alkanes, isoalkanes, cyclics C6 aliphatics
(Shell 1997). This has been read across to n-hexane. The test substance
was 98% degraded at the end of 28 days, and 83% degraded at the end of
the 10 -day window. The reference substance was 104% degraded, therefore
the test is valid. The test substance is readily biodegradable and does
not inhibit degradation. This is supported by QSAR Biowin, a predictive
model for determining quantitative primary biodegradation half-lives for
individual petroleum hydrocarbons. This model uses a fragment-based
approach. The model predicated isohexane to be readily biodegradable.
