- Details on results:
- Analysis of the group with the highest concentration (1000 mg/l) was performed by means of absorption measurement at 615 nm.
The substance is considered not to be dangerous to fish. Due to the intensive colouring by the test substance, the fish were kept in a wire cage which, after suitable periods of time, could be lifted out of the water for the purpose of examining the fish. This was not considered to be dangerous for the fish.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
