The 3-h EC50 value is >100 mg/L in activated sludge from a municipal sewage treatment plant.
The effect of EEA-NH4
on microorganisms was determined in a GLP-compliant study according to
OECD guideline 209 (NOTOX, 2008).
In this limit test,
microorganisms in activated sludge from a municipal sewage treatment
plant receiving predominantly domestic sewage were exposed for 3 hours
to 100 mg/L EEA-NH4 (in duplicate). The test solution was continuously
aerated and stirried.
inhibition (1%) of the respiration rate of the sludge was recorded at
100 mg/L EEA-NH4. Therefore, the EC50 of EEA-NH4 was determined at >100
mg/L (based on nominal concentrations).
