The toxicity potential of the substance to microorganisms was evaluated by taking in consideration experimental data on Similar Substance 01. Justification for Read Across is given in Section 13 of IUCLID.
The study was performed in a static limit test, according to the OECD guideline 209 and not under GLP conditions.
The activated sludge, domestic was exposed to the substance at 100 mg/l under static conditions for 3 hours. The oxygen consumption per hour was measured and the inhibition of respiration activity was evaluated.
The EC50 (3h) of the test material was determined to be > 100 mg/l, based on nominal concentrations. The substance was added to the water without any suspension aid. It was not dissolved but distributed in the test medium.
The substances (analogue and target) are not considered as to inhibit the respiratory sludge bacteria.
