The 48h-EC50 of DL-apha-Tocopherol a closely related stereo isomer and/or structure isomer of the mixed Tocopherols towards Daphnia magna was 23.5 mg/l (measured).
Data from a stereo isomer - D, L, alpha Tocopherol - are available for
read read across to evaluate the toxicity of alpha-Tocopherol against
daphnia. The toxicity of D,L-alpha-TocopheroltowardsDaphnia
magnawas investigated according to OECD Guideline 202 under GLP
conditions (Maetzler, 2000). The measured 48h-EC50 was >23.5 mg/l.
An 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.
