Description of key information
Additional information
Acute studies on aquatic organisms of three different trophic levels are available. The most sensitive organism regarding acute toxicity to aquatic organisms were daphnids. In a test on Daphnia magna an EC50 of 71.2 mg/L was determined. In fish (Chinese Rare Minnow) an LC of 81.5 mg/L was detected whereas algae were less sensitve. In a test on Pseudokirchneriella subcapitata
an EC50 of 101 mg/L was detected.
For the sediment and terrestric compartments the equilibrium partitioning method has been used.
The PNEC STP was calculated using the EC50 of 640 mg/L determined in a respiration inhibition test conducted with domestic, activated sludge.
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).
