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.
