Additional information

The effect of the substance on the respriration rate of activated sludge was determined in a study following OECD guideline 209. The respiration rate was monitored for 30 minutes. Based on the nominal test substance concentrations an EC20 of 1000 mg/l (EC50 >1000 mg/l) was determined (BASF AG 1998).
