The 96-h LC50 in freshwater fish calculated using ECOSAR v1.11 for neutral organics is 81 mg/L.
Giving the physical nature of hexafluoro-1,3-butadiene
and due to the difficulty to test it meaningfully, no experimental
aquatic results are available. Instead, QSAR methods have been used to
estimate the acute toxicity of the substance to aquatic organisms. The
effect concentrations of hexafluoro-1,3-butadiene were
estimated using ECOSAR v1.11 (2012). The measured log Kow value of 2.24
was used for the predictions.
