Description of key information
Short-term toxicity to aquatic invertebrates
In an Acute Immobilisation Test with Daphnia magna according to OECD 202 the 48 hour EC50 of the substance was determined to be 0.369 mg/L (95 % CL: 0.338 – 0.728) based on geom. mean measured concentrations (reference 6.1.3-1).
Toxicity to aquatic algae
In a Growth Inhibition Study according to OECD 201 with Pseudokirchneriella subcapitata the EC50-value for inhibition of growth rate (ErC50) after 72 hours was 0.0993 (0.0950 – 0.108) mg/L. The EC10-value for inhibition of growth rate (ErC10) after 72 hours was 0.0758 (0.0705 – 0.0795) mg/L. The NOEC for the growth rate was 0.0289 mg/L. All results are based on geom. mean measured concentrations (reference 6.1.5-1).
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.
