Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- Evercool 190 undergoes no biodegradation after 67days in the test conditions.
The curves obtained with the reference substance alone and with Evercool 190 + reference substance (see appendixes 1 and 4) show no toxic effect of Evercool 190 to the micro-organisms at the test concentration (100 mg/l).
Thus, Evercool 190 should be regarded as not readily biodegradable according to this test.
