Biodegradation: Readily biodegradable but failing the 10-day window
Ready biodegradability has been determined with a non adapted activated
sludge in the Modified Sturm test. The substance reached the 10% level
(beginning of biodegradation) after 9 days. The test item did not reach
the 60% pass level within the 10-day-window, but after 24 days. The
substance is regarded, as a minimum, as inherently biodegradable and can
be regarded as readily biodegradable though failing the 10 -day window
With adapted sludge, primary degradation in excess of 99% occurred over
28 days and ultimate degradation, measured as CO2 evolution, was 76%
after 28 days.
