Description of key information

The study does not need to be conducted because a reliable ready biodegradability study has been performed with the test substance in accordance with OECD TG 301F (see IUCLID Section 6.1.7 ). Based on the findings of the study, the substance can be considered to be readily biodegradable. In addition, the tested concentration (141.9 mg/L) is excepted to be higher than the influent of a sewage treatment plant.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
141.9 mg/L

Additional information

The no toxic effect concentration to the inoculum in the ready biodegradability test (149.1 mg/L) was used to determind the PNEC STP.
