- yes
- Interpretation of results:
- not inherently biodegradable
- Conclusions:
- Javanol undergoes no biodegradation after 48 days under the test conditions.
The negative biodegradation levels could be interpreted in terms of toxicity of Javanol to the inoculum. However, a previous test (97E78) showed that, at a higher concentration (100 mg/l) Javanol was not inhibitory to activated sludge microorganisms. Hence, the effect presently observed cannot be assigned to toxicity as a general property of Javanol.
Thus, Javanol should be regarded as not inherently biodegradable according to this test. - Executive summary:
The inherent biodegradability of Javanol was determined by the manometric respirometry test according to the OECD Guidelines for testing of chemicals, method No. 302C.
Javanol undergoes no biodegradation after 48 days in the test conditions.
