Toxicity to microorganisms
Administrative data
Link to relevant study record(s)
Description of key information
NOEC (3 hours) of the respiration inhibition of activated sludge microorganisms is 32 mg/L; The EC50 >320 mg/L.
No toxicity to the microorganisms was observed in a Zahn-Wellens Test for biodegradation at 1000 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 32 mg/L
Additional information
An new OECD 209 study, an older OECD209 with some deficiencies and an old Zahn-Wellens test for biodegradation are available. The newest OECD209 study reports an NOEC of 32 mg/L.
The concentration without toxic effect on the microorganisms in the biodegradation study is 1000 mg/L and confirms the low toxicity of the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
