Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Dechlorane Plus was suspended in benzene and then added to test water at a concentration of 4 ppm. Domestic sewage sludge was added, and the mixtures were incubated for 2 - 30 days. The oxygen concentration was determined and compared with negative control values.
- GLP compliance:
- no

Results and discussion
- Transformation products:
- not measured
Any other information on results incl. tables
No oxygen consumption in test and control cultures, sludge was viable after the 30 days incubation period with Dechlorane Plus indicating not toxicity to sludge. No analytical verification of tested substance concentration.
Applicant's summary and conclusion
- Conclusions:
- Test result is not reliable, as not study report is available.
- Executive summary:
Dechlorane Plus was suspended in benzene and added to water together with domestic sewage sludge, while benzene was stripped by aeration. The nominal concentration of 4 ppm was not analytically verified. Within the test duration of 30 days, no oxygen consumption was observed in test and negative control cultures. No test report is availabe, only a summary description in letter form. The test results are not reliable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
