Additional information

The substance was tested for its toxicity on sludge according to the OECD Test guidelines OECD Test Method 209, “Activated Sludge, Respiration

Inhibition Test”, and ETAD Method 103.

A mixed culture of bacteria (sludge of a Husman apparatus) was used and the inhibitory effect of a test substance, its respiration rate expressed as a percentage of the mean of two control respiration rates were calculated.

The IC50 (3 h) is > 100 mg/L.
