EC number: 203-438-2
CAS number: 106-88-7
Acute tests on all
three trophic levels were performed to examine the aquatic toxicity of 1.2
out to be the most sensitive species revealing an EC50 (48h) of 70 mg/L.
Thus, 1.2 -epoxybutane is
considered to be acutely harmful to aquatic organisms. Effects of
1.2 -epoxybutane towards
fish and algae were found in concentrations above 100 mg/L.
No data on long-term
toxicity on fish and Daphnia are available. The hazard assessment of 1.2
neither a need to classify the substance as dangerous for the
environment, nor is it a PBT or vPvB substance. Therefore, and for
reasons of animal welfare, a long-term toxicity study in fish and
Daphnia is not provided.
