The toxicity of 400160 to microorganisms was determined by performing an activated sludge respiration inhibition test according to OECD guideline 209 and EU method C.11 in a GLP certified testing facility.The following results were determined:3h NOEC = 1000 mg/L 3h EC50 > 1000 mg/L3h EC20 > 1000 mg/L

was tested using seven concentrations ranging from 1 to 1000
mg/L. Duration of the test was 3 h. Activated sludge was used as
inoculum. It was taken from a domestic sewage treatment plant and washed
before usage. The dry matter was determined as 2.92 g suspended
solids/L, giving a concentration of 1.46 g suspended solids/L in the
the study no toxic effect could be observed. The oxygen uptake rate at a
concentration of 1000 mg/L was similar as in the control.
was used as positive control. Four concentrations were tested. An EC50
of 8.0 mg/L was determined which was within the demanded range of 2 –
following results for the test item 400160 were determined:
h NOEC = 1000 mg/L
3 h EC20 > 1000 mg/L
h EC50 > 1000 mg/L
