Description of key information
Short term toxicity to fish
One OECD 203 GLP study is available. The EC50 is greater than the maximum water solubility, thus it is not acutely toxic to fish.
Long term toxicity to fish
Based on the acute results of the 3 trophic levels, the chronic daphnia results and the outcome of the resultant chemical safety assessment, the performance of a long-term fish test will have no added value to the risk assessment process
Short term toxicity to aquatic invertebrates
Three OECD 202 GLP studies are available, with one as a supporting study with no analytics and the second one where no analysis was performed and the content of the test concentration is unknown. The third test conducted in 1997 is chosen as the key study, as it meets all the requirements of a valid study. Under the conditions of the test the EC50 (48h) could not be determined and may only be expressed as greater thanthe maximum water solubility in the test.
Long term toxicity to aquatic invertebrates
One OECD 211 GLP test is available with an overall NOEC of 2.7 mg/L (mean measured concentration)
Toxicity to aquatic algae and cyanobacteria
The results of a valid OECD 201 test indicate based on measured data that the EC50 is in excess of the maximum achievable concentration of the active component in the test medium. The conclusion should therefore be no acute or chronic toxicity to algae at the limit of solubility for this test substance. The EL10 (72h, (growth rate) was calculated as 20.23 mg/l (Growth rate) and the EL50 > 838.4 mg/L (growth rate)
Toxicity to microorganisms
One OECD 209 GLP study is available with an 3 hr EC50 > 1000 mg/L (nominal)
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.
