Key value for chemical safety assessment

Additional information

The EC20 value of the test item on activated sludge was found to be greater than 100 mg/L in a guideline study according to OECD 209 (BASF AG 96/0251/08/1, 1996). This result is supported by a GLP study according to DIN EN ISO 10712 in which a EC10 value of 2680 mg/L was determined.
