Description of key information

Respiration inhibition:NOEC - 980 mg/L

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
980 mg/L

Additional information

Respiration inhibition tests with activated sludge have investigated the effects of two structural analogues of the registered substance. No inhibition was observed in either test.

In contrast with the experimental values from the tested structural analogues, QSAR estimates for the registered substance predict IC50 values ranging from 0.58 mg/L to 0.9 mg/L. However, similarly low values are obtained from QSAR estimates of the three structural analogues and it is considered that modelling may not be a reasonable predictor for these substances.
