Description of key information
In a ready biodegradability screening study, the test substance was found to be readily biodegradable and no toxicity was observed in the test cultures at a concentration of 100mg/L. This concentration can be used as a NOEC value.
As the submission substance is readily biodegradable the study is deemed unnecessary.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 100 mg/L
