Description of key information

A sludge respiration inhibition study was performed according to OECD Guideline 209. The 3h-EC50 was determined to be 159.2 mg XDA/L.

Key value for chemical safety assessment

Additional information

Key value for chemical safety assessment:

EC50 for STP micro-organisms: 159.2 mg XDA/L

A sludge respiration inhibition study was performed according to OECD Guideline 209. The results indicated that under the conditions of the test XDI was toxic to activated sludge bacteria with an EC50 of 159.2 mg XDA/L. There were no protocol deviations that significantly affected the study outcome, however high variation between replicates lowered the reliability of the study. A NOEC could not be reliably calculated, as a result of this variability.
