- Biodegradation of the reference substance after 14 d: 80%
- Validity criteria fulfilled:
- not specified
- Interpretation of results:
- not inherently biodegradable
- Conclusions:
- Under the study conditions, the test substance biodegradation was equivalent to 6% after 28 d. The test substance was therefore not considered to be inherently biodegradable.
- Executive summary:
A study was conducted to determine the inherent biodegradability of the test substance according to OECD Guideline 302 C. Sludge (100 mg/L suspended solids) from a predominantly domestic wastewater treatment plant was exposed for 28 d to the test substance at a concentration of 30 mg/L. The theoretical oxygen demand (ThOD) was 1.21 mg 02/mg. The test setup also included a standard reference substance. The biodegradation of the reference substance after 14 d was determined to be 80%. Under the study conditions, the test substance biodegradation was equivalent to 6% after 28 d. The test substance was therefore not considered to be inherently biodegradable (Dietschy, 1997).

- Executive summary:
A study was conducted to determine the inherent biodegradability of the test substance according to OECD Guideline 302 B. Sludge (1020 mg/L suspended solids) from a predominantly domestic wastewater treatment plant was exposed for 28 d to the test substance at a concentration of 398 mg/L (corresponding to 120.6 mg a.i./L). The test setup also included a reference substance, diethylene glycol at 153.6 mg/L. Degradation of the test substance in terms of % TOC was monitored for 28 d. The biodegradation of the reference substance after 14 d was determined to be 100%. Under the study conditions, the test substance biodegradation was equivalent to 33.1%. The test substance was therefore not considered to be inherent biodegradable (Dietschy, 1992).

The oxygen demand was monitored for 28 d. The test setup also included the reference substance aniline. The biodegradation of the reference substance after 14 d was determined to be 75%. Under the study conditions, the test substance biodegradation was equivalent to 5% after 28 d. The test substance was therefore not considered to be readily biodegradable (Mueller, 1993).
