Description of key information
Only few data are available on the acute toxicity of bis(hydroxylammonium) sulfate to fish. In a publication of the National Association of Photographic Manufactures (NAPM 1974) the effects of bis(hydroxylammonium)sulphate on Pimephales promelaswere tested, among other substances, in a static system for 96 hours according to standard procedures outlined in Standard Methods, 13th Edition (ASTM, American Society for Testing and Materials). The LC50 determined in this test was 7.2 mg/l after 96 hours exposure. Basic information about the test is given (dilution water was examined; daily monitoring of pH and dissolved oxygen was conducted). The study is carried out according to an old guideline and without analytical verification of the tested concentrations. Due to these facts, the study is considered as reliable with restrictions. Nevertheless, test results are consistent with results conducted with other aquatic tests, as shown in this risk assessment and may therefore be considered for the aquatic hazard assessment.
Furthermore, in a static test, performed according to an old German guideline with only 48 hours test duration, an LC50 (48h) of 6.67 mg/l was observed for Bis(hydroxylammonium) sulphate (BASF SE, 1976). However, due to insufficient documentation, the validity of the test cannot be evaluated. Nevertheless, since this result is in accordance with those of other available studies, it may be used as supportive information.

Additional information
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.
