Description of key information
No effect at limit of solubilty, estimated to be 8 mg/l
Key value for chemical safety assessment
Additional information
A study to German Water Quality guidelines on Pseudomonas resulted in no effects at the limit of solubility.
In a sludge inhibition study, the EC50 is reported to be > 1000 mg/l. The highest concentration 2500 mg/l resulted in a 6% reduction in respiration. This may be within normal variations for this type of study, but insufficient data are reported to verify the significance.
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.
