One of the people overcome by the gas complained of not being able to get a full breath. This is interesting considering the following regarding sulphur dioxide inhalation.
" Biochemical and biomedical roles
Sulfur dioxide is toxic in large amounts. It or its conjugate base bisulfite is produced biologically as an intermediate in both sulfate-reducing organisms and in sulfur-oxidizing bacteria, as well. The role of sulfur dioxide in mammalian biology is not yet well understood. [19] Sulfur dioxide blocks nerve signals from the pulmonary stretch receptors and abolishes the Hering–Breuer inflation reflex."
From http://en.wikipedia.org/wiki/Sulfur_dioxide
And what the hering-breuer inflation reflex is described in the below link.
