Additional information

The acute toxicity of the test substance to microorganisms has been examined in a GLP guideline study according to OECD 209 with activated domestic sludge from a municipal wastewater plant [BASF SE 2012]. At test termination after 180 min, an EC10 of 110 mg/L (nominal) was determined.
