Study design
- Inoculum or test system:
- other: A mixed population of activated sewage sludge microorganisms.
- Details on inoculum:
- Source: The aeration stage of Severn Trent PLC Sewage Treatment Plant, Belper, Derbyshire.
Preparation:
The activated sludge was maintained at a temperature of 21 ± 1°C for 24 hours. An aliquot of the sludge was added to 10 L of dilution water to give a suspended solids level at 111.35 mg/L (100mg SS/L on dilution for the test) and aerated fo seven days prior to the start of the test to reduce the oxygen demand of the control.
Usage Rate: Equivalent to 100 mg dryweight/l. - Duration of test (contact time):
- 28 d
Initial test substance concentration
- Initial conc.:
- 30 mg/L
- Based on:
- test mat.
- Details on study design:
- Criteria: Oxygen consumption measured by direct manometer reading.
Agitation: By magnetic stirrers
Temperature: 25 +-1 °C
Lighting: The test was carried out in darkness.
Observations: Manometer volumes were recorded daily.
Study Dates: 17th July - 14 August 1990

BOD5 / COD results
- Results with reference substance:
- Aniline attained 48% biodegradation after 7 days and 71% after 14 days thereby confirming the suitability of the inoculum and culture conditions. Total Organic Carbon (TOC) analysis showed that aniline attained 95% degradation after 28 days.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not inherently biodegradable
- Conclusions:
- The test item is not inherently biodegaradable
- Executive summary:
A MITI test (according to Guideline OECD 302 C) was performed due to the low solubility of the test material in water. COD and TOC analysis were not carried out for this reason. 21% degradation after 28 days were found calculated from oxygen uptake and cannot therefore, be considered as inherently biodegradable under the strict terms and conditions of the OECD Guidelines.
