Description of key information

There are seven acute toxicity data available for Cladocera. Two of them were conducted according to international or national guidelines, giving the 48-hour EC50 of 2,400 mg/L for Daphnia magna and the 48-hour LC50 of 1,830 mg/L for Ceriodaphnia sp. (Mount et al., 1997). The lowest valid 48-hour EC50 was 1,062 mg/L for Daphnia magna (Biesinger and Christensen, 1972). The acute toxicity studies with other invertebrates showed LC50 or EC50 values in the range of 780-44400 mg/L. These studies were not conducted according to standard guidelines, but the test conditions were fully described and these data are acceptable.
