Description of key information

With high probability acutely not harmful to fish. No acute toxic effects occur within the range of solubility.

Key value for chemical safety assessment

Additional information

In a 96-h acute toxicity study, zebra-fish (Brachydanio rerio) were exposed to test item at nominal concentrations of 0 (control, solvent control) and 100 mg/L under static conditions (Ciba-Geigy Ltd. 1988).  The 96-h LC50 was > 100 mg/L.  The NOEC, based on mortality and sublethal effects, were ≥ 100 mg/L, respectively.  Sublethal effects were not observed. It can be concluded that the test substance is not acutely toxic to fish at the range of solubility.
