Test material
- Reference substance name:
- Methyltriphenylphosphonium chloride
- EC Number:
- 418-400-2
- EC Name:

Constituent 1
Study design
- Inoculum or test system:
- other: effluent from sewage plant
- Details on inoculum:
- Secondary effluent from a sewage plant was collected on the day of initiation of the test period. The sample was filtered through a paper filter, the first 200 ml were discarded. The remainder of the fIltrate was diluted 1:100 with physiological salt solution and kept under aerobic conditions at room temperature. The total count of viable cells in the fIltrate was in the order of magnitude of 1()6eFU/ml (colony forming units).
- Duration of test (contact time):
- 28 d
Initial test substance concentration
- Initial conc.:
- 1.2 mg/L
- Based on:
- test mat.
Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- O2 consumption
- Details on study design:
- The test was performed in an air-conditioned test room to maintain a constant temperature of 20 +/- 1°C. However, this range of temperature was exceeded on day 0, the minimum and maximum average (two test bottles) temperatures for all series being 21.2/21.3°C. Since the deviation from the recommended temperature range was slight and all series were affected in a similar manner, the observed discrepancy would seem unlikely to influence the validity of the results.
Test series:
C: control: dilution water, mineral nutrient solutions without inoculum
B: inoculation blank
dilution water, mineral nutrient solutions and 50 uIll of inoculum.
R: reference: dilution water, mineral nutrient solutions, 50 ul/1 of inoculum and 2 ml of the reference solution (sodium benzoate, 1 g/l) => test concentration 2 mg/l
T: sample: 20 ml of the test article stock solution, mineral nutrient solutions as well as 50 ul of inoculum. => test concentration 1.2 mg/l
Reference substance
- Reference substance:
- benzoic acid, sodium salt
Results and discussion
% Degradation
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- 21.5
- Sampling time:
- 28 d
- Details on results:
- The chemical oxygen demand of the reference substance sodium benzoate and the test article was determined experimentally according to IBR SOP/91/X/04 based on photometric analysis of COD using COD test vials (0-1500 mg COD/mg, HACH).
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- The percentage biodegradation of the test substance was 21.5% at the end of the test under the conditions of the study, so the test substance cannot be considered to be readily biodegradable.
