Measured data are not available for buta-1,2 -diene
for this endpoint. Due to the practical difficulties associated with the
ecotoxicity testing of gases (i.e. maintaining exposure concentrations)
the use of QSAR toxicity estimates is an appropriate alternative. The
ECOSAR model is a reliable and appropriate QSAR model to apply to buta-1,2
-diene as it is based on a related chemical dataset that calculates the
toxicity of neutral organic hydrocarbons whose mode of action is
non-polar narcosis. The endpoint calculated here is therefore a
reasonable estimate of its baseline toxicity.
