96-h LC50 (based on loading rates) >100 mg/L for Oncorhynchus mykiss (OECD TG 203, EU C.1)

Key value for chemical safety assessment

Additional information

The results obtained for the read-across source substance WS405777 indicate that the test material is not toxic to fish up to the limits of its water solubility (<1 mg/L) and a NOEC and thus a PNEC cannot be determined.

The same conclusion can be drawn for the read-across target substance WS406663 based on the close chemical similarity between the two substances (see IUCLID Section 13 „Validity Assessment Report“ for the read-across approach).
