Description of key information
In an 48-hour acute toxicity test on Daphnia magna an EC50 of 9.1 mg/L was observed.
In a Growth Inhibition test with the algal Raphidocelis subcapitata a 72-hour NOEC based on growth rate and yield was determined to be 1.4 mg/L and the LOEC as 4.1 mg/L. An EC10 and EC50 based on growth rate of 4.4 and 16.7 mg/L were observed, respectively. The EC10 and EC50 values based on Yield were 1.5 and 5.7 mg/L, respectively.
Additional information
An acute Daphnia magna Immobilisation Test was performed according to OECD Guideline 202. The purpose of this study was to evaluate the influence of the test item on the mobility respectively survival of Daphnia magna. Young Daphnia were exposed to test item concentrations of 1.25, 2.5, 5, 10 and 20 mg/L (nominal) for 48 hours under static conditions. The determined 48h-EC50 was 9.1 (95% CL: 7.7. - 10.6).
A Growth Inhibition Test with the algal Raphidocelis subcapitata was performed according to OECD Guideline 201. Exponentially growing cultures of Raphidocelis subcapitata were exposed to test item concentrations of 0.5, 1.4, 4.1, 11.9, 34.5 and 100 mg/L. An EC10 and EC50 based on growth rate of 4.4 and 16.7 mg/L were observed, respectively. The EC10 and EC50 values based on Yield were 1.5 and 5.7 mg/L, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
