The 48h-EC50 of D,L-alpha-Tocopherol, a structure isomer to to alpha-Tocopherol towards Daphnia magna was > 23.5 mg/l (measured).
Data from a stereo isomer - D, L, alpha Tocopherol - are available to
evaluate the toxicity of alpha- Tocopherol against daphnia. The toxicity
of D,L-alpha-Tocopherol towards Daphnia magna was
investigated according to OECD Guideline 202 under GLP conditions
(Maetzler, 2000). The measured 48h-EC50 was >23.5 mg/l.
The acute toxicity study is also for DL-alpha-tocopheryl acetate
to D. magna available: Toxicity was investigated in a static test
system following German standard DIN 38412, part L11. The 48h EC0 was
500 mg/l and the 48h EC50 was >500 mg/l (BASF AG, 1988). The study was
considered to be a supporting study.
