Description of key information

The inhibition of the degradation activity of activated sludge is not expected when introduced in appropriate low concentrations.

Key value for chemical safety assessment

Additional information

The toxicity of 2 -chloroethanol to microorganisms was investigated in an activated sludge respiration study similar to the OECD guideline 209. No inhibition was observed during the 30 min exposure period at the highest tested concentration 200 mg/L (BASF AG, 1978).
