Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test)

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- All validity criteria were met. Degradation behaviour of positive control and toxicity control was normal. Abiotic degradation was not observed. Both replicates of the test item showed very good correspondence. If degradation in the toxicity flask is below 25% after 14 days, the test item can be considered as toxic towards the inoculum. As degradation in the toxicity flask was 37% after 14 days, the test item can be stated as “not toxic towards the inoculum in a concentration of 206.6 mg/L”. The result of the test can be considered valid. The test item 5-Aminotetrazol Potassium is considered as “not readily biodegradable“. The degree of biodegradation reached 4 % after 28 days. No 10-day-window could be identified and the pass level of 60 % given in the OECD guideline was missed. No abiotic degradation was observed.
- Executive summary:
The test item 5-Aminotetrazol Potassium was tested using a concentration of nominally 20 mg organic carbon/L (corresponding to 205.2 mg 5-Aminotetrazol Potassium/L) in test
medium following OECD 301B and EU-Method C.4-C. Aniline was chosen as positive control. Activated sludge was used as inoculum (concentration in the test 25.1 mg dry matter/L). The test was left running for 28 days. All validity criteria were met. Degradation of the positive control was 75 % after nine days. The following data could be determined for the test item 5-Aminotetrazol Potassium:
10-day-window: not detected
degradation at the end of 10-day-window: none
degradation at the end of the test 4 %
pass level: 60% at the end of 10-day-window
Therefore, regardless of the 10-day-window, 5-Aminotetrazol Potassium is not readily biodegradable following OECD 301B/EU C.4-C.
