Description of key information
Short term toxicity to freshwater invertebrates:
A study was performed to assess the acute toxicity of the test material to Daphnia magna. The method followed that described in the OECD TG 202, "Daphnia sp, Acute Immobilisation Test" referenced as Method C.2 of Commission Directive 92/69/EEC. The 48-hour EC50 for the test material to Daphnia magna based on nominal test concentrations was greater than 100 mg/L. The No Observed Effect Concentration (NOEC) was 10 mg/L.
Toxicity to aquatic algae and cyanobacteria:
A study was performed to assess the effect of the test material on the growth of the green alga Desmodesmus subspicatus. The method followed that described in the OECD TG 201, "Freshwater Alga and Cyanobacteria, Growth Inhibition Test" referenced as Method C.3 of Commission Directive 92/69/EEC.
In terms of growth rate, exposure of Desmodesmus subspicatus to the test material gave an ErC50 (0-72 h) value of 110 mg/L. The Lowest Observed Effect Concentration (LOEC) based on inhibition of growth rate was 100 mg/L and the No Observed Effect Concentration (NOEC) was 32 mg/L. In terms of yield, exposure of Desmodesmus subspicatus to the test material gave an EyC50 (0-72 h) value of 85 mg/L. The Lowest Observed Effect Concentration (LOEC) based on yield was 100 mg/L and the No Observed Effect Concentration (LOEC) was 32 mg/L. In terms of biomass integral (area under growth curve), exposure of Desmodesmus subspicatus to the test material gave an EbC50 (0-72 h) value of 90 mg/L. The Lowest Observed Effect Concentration (LOEC) based on inhibition of biomass integral was 100 mg/L and the No Observed Effect Concentration (NOEC) was 32 mg/L.
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.
