- Effect data (Immobilisation): No. of immobile daphnia
Control: 0 (24 h) / 0 (48 h)
0.40 mg/l: 0 (24 h) / 0 (48 h)
0.61 mg/l: 0 (24 h) / 0 (48 h)
0.83 mg/l: 0 (24 h) / 0 (48 h)
1.3 mg/l: 14 (24 h) / 15 (48 h)
2.0 mg/l: 20 (24 h) / 20 (48 h)
3.5 mg/l: 20 (24 h) / 20 (48 h)
4.9 mg/l: 20 (24 h) / 20 (48 h)
EC50 (24 hours) = EC50 (48 hours) = 1.1 mg/l
The acute toxicity of 1,5 -cyclooctadiene on Daphnia magna was
investigated in a 48 -h test by Hüls AG (1998) according to EU method
C.2. Seven concentrations ranging from 0.4 mg/L to 4.9 mg/L (mean values
of measured concentrations) plus controls were tested. The following
endpoint was derived:
EC50 (48 hours): 1.1 mg/L
The study was assessed as "reliable without restrictions".
