Description of key information

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

Key value for chemical safety assessment

Additional information

Since no test data on the toxicity of monoethylene glycol to aquatic microorganisms are available a conclusion by analogy approach to diethylene glycol (CAS 111-46-6) has been applied. No inhibition observed in an activated sludge respiration inhibition test after an incubation time of 30 minutes [BASF AG, 1982].
