The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
In a 3-hr acute toxicity study sewage sludge microorganisms were exposed
to the test item at nominal concentrations of 102.8, 32.9, 11.3, 3.1 and
1.4 mg/L in accordance with OECD 209. The IC50 value based on
respiration rate was bigger than 102.8 mg/L after a 3 h contact time.
This toxicity study is classified as acceptable and satisfies the
guideline requirements for OECD 209 toxicity study.
