Description of key information

The test item showed 43 % and 44.4 % respiration inhibition of activated sludge at the highest test item concentration of 10000 mg/L. 
An EC50 of >10000 mg/L were obtained in this test. The effect value relates to nominal concentration, since no analytical monitoring was performed

Key value for chemical safety assessment

EC50 for microorganisms:
10 000 mg/L

Additional information

Should read > 10000 mg/L

Read-across appears to be justified as the substance to be registered and the read-across substance are identical in structure. The substance to be registered is the salt of the read across substance.
