Description of key information
Additional information
Data on the acute aquatic toxicity of trimanganese bis(orthophosphate) are available for fish, Daphnia, algae.
The acute toxicity of the substance to fish was investigated in a study following guideline OECD 203.Zebrafish (Danio rerio) were exposed to the substance for 96 hours under static conditions. Detrimental effects were not observed and a LC50(96 h) > 5.3 mg/l (mean measured concentration) was reported. The study on the acute toxicity to Daphnia magna was conducted according to OECD guideline 202. The test animals were exposed for 48 hours. At test termination an EC50(48 h) >5.63 mg/L (mean measured concentration) was determined.The available study on the toxicity of trimanganese bis(orthophosphate) to algae was conducted according to OECD guideline 201. The algal growth was not affected by the substance and an EC50(72h) >4.41 mg/L (measured initial) was determined.
Experimental data on the toxicity to microorganisms are not available for trimanganese bis(orthophosphate). The assessment is therefore based on read across data for manganese hydrogen phosphate (CAS 51349-94-1). The study was performed according to OECD 209. The determined EC50 (3 h) was > 1000 mg/L. The No Observed Effect Concentration (NOEC) after 3 hours exposure was 1000mg/L.Based on the available information trimanganese bis(orthophosphate) an acute toxicity of the substance to aquatic organisms is not anticipated.
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.
