- yes
- Interpretation of results:
- other: moderately biodegradable
- Executive summary:
The test item Sa 190 / SAT-No. 080004 is considered as "moderately biodegradable". The degree of biodegradation reached 57 % after 28 days. The 10-day-window began on day 14, at its end, 46 % were reached, missing the pass level of 60 % given in the OECD guideline. Abiotic degradation was not observed.
