Description of key information

The test substance is with high probability not acutely harmful to aquatic algae. No acute toxic effects occur within the range of solubility.

Key value for chemical safety assessment

Additional information

The acute toxicity to aquatic algae has been investigated in a GLP guideline study according to OECD 201 (BASF SE 2010). Due to the low solubility of the test substance in water a saturated solution has been tested. After 72 h the EC50 values based on yield and growth rate are > 100 mg/L (loading rate). The NOECs are determined to be ≥ 100 mg/L (loading rate) based on yield and growth rate. Therefore, no acute toxic effects ocurred within the range of solubility.
