- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test)
- Deviations:
- yes
- Remarks:
- All three deviation are considered as "uncritical concerning the outcome of the study."
- GLP compliance:
- yes (incl. QA statement)
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic, non-adapted
- Details on inoculum:
- Activated sludge from a biologic sewage treatment plant was used as inoculum. The chosen plant treats mostly domestic sewage.
The sludge was taken from the activation basin of the ESN (Stadtentsorgung Neustadt) sewage treatment plant, Im Altenschemel, 67435 NW-Lachen-Speyerdorf.
Date of collection: 31. Oct. 2019, batch no: E20191031.
The sludge was filtrated, washed with test medium (2x) and re-suspended in test medium. It was then aerated until use. The dry matter was determined to contain 3.10 g of suspended solids/L. - Duration of test (contact time):
- 28 d
- Initial conc.:
- 20 mg/L
- Based on:
- TOC
- Parameter followed for biodegradation estimation:
- CO2 evolution
- Details on study design:
- Flask volume 1500 mL
Apparatus blanks 2, containing mineral medium only
Blank Controls 2, containing mineral medium and inoculum
Positive control flasks 2, containing positive control, mineral medium and inoculum
Test flasks 2, containing test item, mineral medium and inoculum
Abiotic control 1, containing test item, mineral medium and HgCl2
Toxicity control 1, containing test item, positive control, mineral medium and in-oculum
Inoculum concentration: 25.0 mg/L
Temperature 19.2 – 21.1 °C without direct lighting
