Result: Within the test period of 28 days, a degradation of 0 % was determinded for Reaktiv-Orange DYPR 934. Reaktiv-Orange DYPR 934 has to be classified as “Not Readily Biodegradable”
Biodegradability:
0 % (28 d)
Method: Modified OECD Screening Test
The test results indicate no hazard potential.
The test substance is not readily biodegradable; so longer resident times of the substance in surface water are to be expected. However on the basis of the ecotoxicological test results there is no hazard potential.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- The test results indicate no hazard potential.
The test substance is not readily biodegradable. - Executive summary:
Result: Within the test period of 28 days, a degradation of 0 % was determinded for Reaktiv-Orange DYPR 934. Reaktiv-Orange DYPR 934 has to be classified as “Not Readily Biodegradable”
Biodegradability = 0 %
The test results indicate no hazard potential.
