The toxic potential of the substance to
microorganisms was evaluated by considering data on Similar Substance
01, due to the absence of data on the substance itself. Justification
for Read Across is given in Section 13 of IUCLID.
The effect of the substance on the
respiration of activated sludge obtained from a domestic sewage
treatment plant was evaluated according to the OECD Guideline 209 and EU
method C.11. The effects on micro-organisms from activated sludge were
determined by measuring their respiration rate under defined conditions
in the presence of different concentrations (1, 10, 100, 1000 mg/l) of
the test substance. The respiration rates of samples of activated sludge
fed with synthetic sewage were measured in an enclosed cell containing
an oxygen electrode after a contact time of 3 hours. The sensitivity of
each batch of activated sludge was checked with a positive control.
