Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, non-adapted
- Duration of test (contact time):
- 28 d
Parameter followed for biodegradation estimation
- Parameter followed for biodegradation estimation:
- O2 consumption
- Details on study design:
- The amount of oxygen consumed by the microorganisms when metabolising the test item is called Biochemical Oxygen Demand (BOD). The BOD of test item is determined by the manometric respiratory - OxiTop® system. The principle of the determination of BOD by OxiTop® - system is based on the measurement of the consumption of oxygen by a pressure sensor in the top of the tightly closed test vessels. Test vessels with the test item solution and mixed bacterial culture, so called inoculum, are under continuous stirring in an incubator at 21 ± 1 °C for 28 days. The carbon dioxide which is evolved during the biodegradation is absorbed by sodium hydroxide granulates. The reduced amount of oxygen causes definite pressure changes in the test vessels which are measured by the apparatus. The amount of oxygen taken up by microorganisms during biodegradation of the test item is expressed as a percentage of theoretical oxygen demand (ThOD). The percentage of biodegradability of the test item is calculated on the base of quotient of 28-day biochemical oxygen demand (BOD28) and theoretical oxygen demand. The pass level for the biodegradability is 60% of ThOD for Manometric Respirometry method. The pass value has to be reached in 10 days (10-d) window within the 28-day period of the test. The 10-d window begins when the degree of biodegradation has reached 10% ThOD and must end before day 28 of the test. Biodegradability classification of the test item is made according to OECD 301 guideline, which says that chemicals which reach the pass level up to 28-d period are deemed to be readily biodegradable.
Reference substance
- Reference substance:
- acetic acid, sodium salt
Results and discussion
- Test performance:
- Preparation of inoculum test culture: Before the test 300 ml stock culture was filtered through a filter with 0.2 mm pore size to remove the bigger insoluble particles and then the dry substance content of the filtrate was determined. The measured value was 4.44 g/L. For preparing the inoculum culture 155 ml mineral medium was added to 45 ml filtered stock culture. The calculated dry mass of inoculum culture was 1 g/L.Preparation of reference solution: For the reference solution 320.21 mg sodium acetate was diluted in 100 ml mineral medium.Preparation of test vessels: Following test vessels were prepared and analysed for the study:- Test item (in two replicates)- Blank control (in two replicates)- Reference solution (positive control)- Reference and test item solution (toxicity control)- Sterilized solution of test item (abiotic control)
