Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 2003
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Considering the structural similarities of the substances "Iodo(triphenylphosphino)copper" and "Iodotris(triphenylphosphino)copper" and the almost identical physical and chemical properties, especially partition coefficients and water solubilites, it can be expected that these substances will show quite similar behaviour with respect to their biodegradability behaviour, too.
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- other: OECD 301B (Mod. Sturm)
- GLP compliance:
- yes
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: 219001
- Expiration date of the lot/batch: Sept. 23rd 2003
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: The test item was stored in a closed polyethylene vessel at room temperature.
- Stability under test conditions: in solution at room temperature stable for at least 96 hours - Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge (adaptation not specified)
- Details on inoculum:
- Activated sludge from a biologic sewage treatment plant was used. The chosen plant is
treating mostly household sewage. - Duration of test (contact time):
- 28 d
- Parameter followed for biodegradation estimation:
- CO2 evolution
- Reference substance:
- other: Anilin
- Preliminary study:
- Before the start of the test, the toxicity of the test item towards activated sludge was determined in a separate study (respiration inhibition test).
The test item didn't have a toxic effect on the activated sludge. The carbon content of 66 % was determined from the formula. The test item was directly weighed into the test flasks. - Parameter:
- other: degradation
- Value:
- 12
- Sampling time:
- 28 d
- Details on results:
- Points of degradation plot (test substance):
0 % degradation after 2 d
3 % degradation after 4 d
6 % degradation after 8 d
6 % degradation after 15 d
9 % degradation after 21 d
12 % degradation after 28 d - Results with reference substance:
- Points of degradation plot (reference substance):
0 % degradation after 2 d
1 % degradation after 4 d
60 % degradation after 8 d
81 % degradation after 15 d
81 % degradation after 21 d
97 % degradation after 28 d - Validity criteria fulfilled:
- yes
- Interpretation of results:
- other: not readily biodegradable
- Conclusions:
- The test item is considered as „not readily biodegradable".
- Executive summary:
The test item is considered as „not readily biodegradable".
Reference
The 10 d-window began on day 24, therefore the criteria of the pass level of 60% within 10 days given in the OECD guideline couldn 't be determined.
The degree of biodegradation reached 12 % after 28 days.
The test item is considered as „not readily biodegradable".

Description of key information
Not readily biodegradable, shown on a structural analogue.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Results on the structural similar compound Iodotris(triphenylphosphino)copper suggest a low biodegradability for Iodo(triphenylphosphino)copper, too.
