Key value for chemical safety assessment
Additional information
An old report on a study to assess acute toxicity of Acid Brown 303 to fish was available. Test duration was 48 h and test concentrations were 1000, 2000, 3000, 4000, 5000 ppm (wt/vol.). An LC50 value was determined.
However, due to the lack of details on test procedure (e.g. number of tested fish per concentration, exposure conditions, appearance of test solutions...) and results, the reliability of the data could not be ascertained.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
