Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 the aquatic toxicity studies microorganisms (EC50[180min]=140 mg/L) were clearly less sensitive than fish (EC50[96h]=4.6-10 mg/L), Daphnia magna (EC50[48h]=3.5 mg/L) and algae (EC50[72h]=97 mg/L) indicating that prokaryotic cells are less sensitive than eukaryotic cells. The most sensitive acute endpoint is 50-fold lower than the result of the activated sludge respiration inhibition test. Hence it is very unlikely that terrestric micro-organisms are more sensitive than terrestrial plants.
