Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

96 h EC50 >12 µg/L, Pseudokirchneriella subcapitata, measured (Springborn Smithers 2001)
96 h NOEC ≥12 µg/L, Pseudokirchneriella subcapitata, measured (Springborn Smithers 2001)

Key value for chemical safety assessment

Additional information

A 96-hour ErC50 of >12 µg/L has been determined for the effects of the test substance on growth rate of Selenastrum capricornutum (new name Pseudokirchneriella subcapitata). A NOEC of ≥12 µg/L has been determined in the same test.

The results of a second test (the reliability of which cannot be determined) also showed an absence of toxicity following short-term exposure to a treatment level that was above the solubility of the substance.
