The sludge was gently aerated and then settled prior to the supernatant being poured off and added to mineral media. this procedure was repeated twice. After the third time the supernatant was poured off and 2.0 mL of stirred concentrated sludge was dispensed onto pre-weighed aluminium weigh boats.

The validity of the test is confirmed by test on blank control and on reference substance.
Total CO2 evolution in the inoculated control (nutrient blank) did not exceed 70 mg/L at any point thoughout the test, thereby meeting the test validity criteria.
The reference substance achieved 68.3% biodegradation in 14 days and 78.8% in 28 days satisfying the acceptability criteria (i.e. ≥60% biodegradation in 14 days).

- Inoculum or test system:

- Details on inoculum:
- Activated sludge, surface soil and surface water were sampled from ten sites distributed in four districts throughout Najing city. 1L of the sludge, soil and water were collected and mixed thoroughly together. After removing floating matter the mixture was allowed to stand and then the supernatant is filtrated through 0.45 µm Millipore filter. After that the filtrate was adjusted the supernatant to pH 7.0 with sodium hydroxide or phosphoric acid. Finally an appropriate volume of the filtered supernatant was transferred to a fill-and-draw activated sludge vessel and aerated for about 23.5 h. Thirty minutes after stopping the aeration, about one third of the whole volume of supernatant was discarded. then an equal volume of the solution (pH 7.0) containing 0.1% each of glucose, peptone and potassium orthophosphate was added into the settled material and aerated again. this procedure was repeated once per day during one month. Before use the mixture was allowed to stand and the supernatant was removed. A small quantity of sludge was taken to be centrifudged (2500 r/min x 10 min) and then weighed. then the sludge was dried in the oven and weighed again in order to calculate the content of dried sludge was 10%.
At last 10g of centrifugated sludge was diluted 1L with basal culture medium (BSM) to get activated sludge suspension with a concentration of 1000 mg/L (dry basis). - Duration of test (contact time):

- Details on study design:
- Test solutions were prepared in an organic salts medium, inoculated with a number of microrganisms collected from not less than 10 places in Najing city.
Four groups were set up simultaneously : the "abiotic" contained mineral salts medium and a measured amount of test substance in order to determine, whether there was any change in the test chemical during the testing period, the "procedure control" contained inoculated mineral salts medium and a measured amount of a reference substance for validating the test results. The "control" only contained inoculated mineral salts medium, while the "test" contained inoculated mineral salts medium and a measured amount of test substance.
The progress of degradation was followed by the determination BOD in the "test" and "control". Degradation was expressed as the rationof the biochemical oxygen demand (BOD) and chemical oxygen demand (COD) in order to evaluate the inherent biodegradability of chemical substance. The inherent degradation rate was also expressed as percentage of initial concentration of test substance where the residue analysis of the test substance was performed at the end (28d) of the test. - Reference substance:
