Description of key information
OECD Guideline 203-EU-Method C.1_Oncorhynchus mykiss: Based on nominal loading rates of Water Soluble Fractions (WSF): LC50 = 11.0 mg/L; NOEC = 5.6 mg/L. Based on test material present in WSF: LC50 = 4.5 mg/L; NOEC = 2.1 mg/L.
Key value for chemical safety assessment

Additional information
In a study the acute toxicity of the compound to Oncorhynchus mykiss was investigated, following OECD Guideline 203 as well as EU Method C.1 and US-EPA OTS 797 -1400. Fish were exposed, in groups of 10, to a Water Soluble Fraction (WSF) of the test material over a range of loading rates of 3.2, 5.6, 10, 18 and 32 mg/L for 96 hours under semi-static test conditions. Effect concentrations based on nominal loading rates of Water Soluble Fractions (WSF): LC50 = 11.0 mg/L; NOEC = 5.6 mg/L. Analysis of the test preparations at 0, 24 and 96 hours confirmed that there was no significant change in phosphorus concentration over the duration of the study. Therefore based on the results of the test sample analyses the LC50 values were also calculated in terms of the amount of test material present in the WSF: LC50 = 4.5 mg/L; NOEC = 2.1 mg/L.
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.
