Description of key information

- 279 mg/L
- EC10 or NOEC for microorganisms:
- 100 mg/L
Additional information
The test item showed under the conditions of the study that it will have an inhibitory effect on sewage sludge respiration if released to a waste water treatment plant.
The effect of the test item on the respiration of activated sewage sludge gave a 5 minute EC50 of 270 mg/l. The no observed effect concentration (NOEC) after 5 minutes exposure was 100 mg/l.However, due to the volatility of the substance under the test conditions, the EC50 value obtained after 5 minutes can only be based on a nominal substance loading value. Therefore, the EC50 value should be treated with some caution when considering hazard identification and risk characterization for the appropriate environmental compartment.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
