Additional information

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.
