The test item attained 63 % biodegradation after 28 days and can therefore be considered to be readily biodegradable (OECD 301B).
study was performed to assess the ready biodegradability of the test
item in an aerobic aqueous medium. The method followed was designed to
be compatible with the OECD Guidelines for Testing of Chemicals (1992)
No 301B "Ready Biodegradability; CO2 Evolution Test" referenced as
Method C.4 -C of Commission Regulation (EC) No 440/2008 and US EPA Fate,
Transport, and Transformation Test Guidelines OCSPP 835.3110 (Paragraph
test item, at a concentration of 10 mg Carbon/L, was exposed to
activated sewage sludge micro-organisms with mineral medium in sealed
culture vessels in the dark at 18 to 23 °C for 28 days.
biodegradation of the test item was assessed by determination of carbon
dioxide produced. Control solutions with inoculum and the reference
item, sodium benzoate, together with a toxicity control were used for
test item attained 63 % biodegradation after 28 days and therefore be
considered to be readily biodegradable.
The test item attained 63 % biodegradation
after 28 days and can therefore be considered to be readily
biodegradable. The test item failed to meet the 10-Day window validation
criterion, whereby 60% biodegradation must be attained within 10 days of
the biodegradation exceeding 10%. However, in accordance with the
Revised Introduction to the OECD Guidelines for Testing of Chemicals,
(2006), if testing on a complex mixture is performed and it is
anticipated that a sequential biodegradation of the individual
structures takes place, then the 10-Day window should not be applied to
interpret the results of the test.
