Description of key information

Toxicity to microorganisms: no significant inhibition of respiration rates (OECD 209).

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 sewage bacteria 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.
