- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and package No.of test material: manufactured in Sevelen, lot #51716
- Expiration date of the lot/batch: 09.04.2019
- Purity test date: - Oxygen conditions:
- aerobic
- Inoculum or test system:
- other: Activated sludge from municiipal sewage treatment plant
- Details on inoculum:
- The test has been accepted internationally for determining the 'ready' biodegradability of test items under aerobic conditions.
- Pretreatment: sieved 1mm
- Concentration of sludge: 2.4 g/L; 7.2 mg/L
- Initial cell/biomass concentration:
- Water filtered: yes/no
- Type and size of filter used, if any: - Duration of test (contact time):
- >= 28 - <= 28 d
- Initial conc.:
- >= 16.5 - <= 16.5 mg/L
- Based on:
- test mat.
- Parameter followed for biodegradation estimation:
- CO2 evolution
- Details on study design:
- The study consisted of eight bottles:
- 2 inoculum blanks (no test item),
- 4 test bottles (03590),
- 1 procedure control (sodium acetate) and
- 1 toxicity control (03590 plus sodium acetate). - Reference substance:
- acetic acid, sodium salt
- Test performance:
- The relative biodegradation values calculated from the measurements performed during the test period revealed 57%, 75%, 64%, and 54% biodegradation of 03590, for vessel A, B, C and D, respectively (based on ThCO 2 ). Average biodegradation of the test item after 28 days is 63%.
- Key result
- Parameter:
- % degradation (CO2 evolution)
- Value:
- >= 63 - <= 63
- St. dev.:
- 8
- Sampling time:
- 28 d
- Remarks on result:
- other: readily biodegradable
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- In conclusion, 03590 was designated as readily biodegradable.
- Executive summary:
The relative biodegradation values calculated from the measurements performed during the test period revealed 57%, 75%, 64%, and 54% biodegradation of 03590, for vessel A, B, C and D, respectively (based on ThCO 2 ). Average biodegradation of the test item after 28 days is 63%. Since the test item consists of a mixture of structurally similar chemicals, the 10-day window need not be applied.
