Description of key information
Additional information
Short-term tests are available for aquatic invertebrates (freshwater as well as marine species), algae and fish. The endpoints for the three relevant aquatic trophic levels are in the same order of magnitude. The LC50 (48 h) for Ceriodaphnia conforms dubia was 4.53 mg/L (Warne & Schifko, 1999) and 2.08 mg/L (calculated for 100% substance) for Acartia tonsa. For algae, the EC50 (72 h) was determined to be 1.97 mg/L (calculated for 100% substance) (Hushagen, 1997). The LC50 (96 h) for zebra fish (Danio rerio) resulted in 4.2 mg/L (Markert & Weigand, 1984). One chronic result within a 21-d reproduction study is available with a NOEC of 2.42 mg/L (calculated for 100 % substance) for Daphnia magna. The NOEC for algae was 1.2 mg/L calculated for 100% substance. The effect concentration is within the range obtained in tests on acute toxicity.
For aquatic microorganisms, an activated sludge respiration inhibition test according to OECD guideline 209 has been performed resulting in a 3-h EC50 of 230 mg/L (Janssen, 1989).
