Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

In a reliable standard static test with Daphnia magna no adverse effects were reported at 10000 mg/L after 48-h exposure (Kuehn, 1989). Toxicity values well above 10000 mg/L reported also for Daphnia magna in other studies support this finding: 22200 mg/L (EC50, 48h) (Rossini and Ronco 1996), 20803 mg/L (EC50, 24h) (Lilius et al. 1995), and 22910 mg/L (LC50, 24h) (Reiff 1976). Aditionally short-term toxicity data are available from tests conducted with other test organism: Mytilus edulis, LC50 (96h) = 15900 mg/L (Helmstetter et al. 1996) and Moina micrura, LC50 (96h) = 4820 mg/L. Although the lowest toxicity was reported for Moina micrura this is not a standard organism, which does not occur in cold-temperate regions. For this reason it is considered less relevant than Daphnia and was not used in in the PNEC derivation.
