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.
