1) Key: A long-term reproduction study with invertebrates (Daphnia magna) (21days) (K1) (OECD 211 & GLP) resulted in an EC10 (21days, reproduction) = 0.0045 mg/L (estimated by extrapolation).
There is one test available which evaluates the long-term toxicity
effects towards aquatic invertebrates (per GLP and OECD211)(Sacker,
2010). Waterfleas (Daphnia magna) were exposed to DAPD for 21
days in order to evaluate the effects of the substance on the
reproductive output of the organisms. At the end of the test, the live
offspring per parent Daphnia (alive) was evaluated. An EC10
(21 days; reproduction) of 0.0045 mg/L (estimated by extrapolation) was
calculated and the lowest observed effect concentration (LOEC -
reproduction) after 21 days was determined at 0.007 mg/L. In the same
test the no observed effect value (NOEC) for parent Daphnia
survival (21 days) was 0.016 mg/L, the EC10
(survival, 21 days) was 0.027 mg/L. .
