A range-finding test was followed by a final EC50 test performed under
static conditions for 24 hours of exposure. The range-finding test
showed a 24 EC50 value between 100 and 1000 mg/l.
In the final EC50 test Daphnia were therefore exposed for a maximum of
24 hours to nine different concentrations (5000, 2500, 1250, 625, 320,
160, 80, 40, 20, 0 mg/l)
The study included a blank-control. The test was performed in
quadruplicate with 5 daphnia
per vessel. The 24h EC50 was determined to > 300 mg/l (95% CL: 120 - 800
24 h EC50 (reference substance) = 1.82 mg/l
