Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Test guideline
according to guideline
other: American Public Health Association 1975
not specified
Principles of method if other than guideline:
American Public Health Association 1975 Bioassays were performed under two different temperatures (22.7oC and 30.8oC) for 72-h in 500 mL beakers for plankton and for 96-h for other animals. Each container held 20 animals and six replicates were used for each test.
