EC number: 811-213-0
CAS number: 66711-86-2
Analytical results of the test solutions after 28 days were as follows.
Percentage biodegradations were as follows.
This study was aimed at evaluating the biodegradability of the test
substance by microorganisms according to the closed bottle test (OECD
Conditions of incubation are as follows,
Concentration of test item: 6.25 mg/L
Concentration of inoculum: 0.05 mL/L
Volume of test solution: 100 mL
Incubation temperature: 20±1°C
Incubation method: Stationary incubation in sealed condition
Incubation duration: 28 days (under dark condition)
Measurement and analysis for calculation of percentage biodegradation:
Measurement of dissolved oxygen by diaphragm electrode method (DO) and
Determination of test item by gas chromatography (GC). The mean
percentage biodegradation by BOD and that of the test item after 28 days
were 5% and 2%. The test item was not readily biodegradable as the pass
level of 60% BOD was not achieved during the test.
