Description of key information
Short-term toxicity to fish
The test material does not possess acute toxic potential to fish up to the limit of solubility in water. The LC50 of the test material exceeds 99.4 mg/L (with solubilizer) and is clearly above the limit of water solubility.
Long-term toxicity to fish
The test material showed no toxic potential at concentrations at or above the water solubility. The NOEC was >= 0.02 mg/L and thus higher than the limit of water solubility.
Short-term toxicity to aquatic invertebrates
An aqueous solution of nominal 100 mg/L of the test item revealed no aquatic toxicity in the test system. The 48 hour EC50 for Daphnia magna exceeded the maximum solubility of the test material in reconstituted water (< 0.9 mg/L) and, thus, could not be determined in this test.
Long-term toxicity to aquatic invertebrates
The test substance had no effect on the reproductive performance of Daphnia magna up to the limit of 100 mg/L (nominal) as tested in a GLP compliant OECD 211 assay.
Toxicity to aquatic algae and cyanobacteria
The source substance of this read across revealed no toxic effect on the growth of algae after 72 h at a nominal concentration of 100.0 mg/L. Analytically, the 72 hours EC50 to algae could not be determined; it exceeded the maximum solubility of the test material in reconstituted water (< 0.005 mg/L).
Toxicity to microorganisms
The source substance of this read across had no effect on the respiration rate of activated sludge as tested in a GLP compliant OECD 209 assay. The 3 -h EC20/80 and EC50 were clearly higher than 1000 mg/L under the present test conditions.
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.
