I don't know about "one breath"; the number of breaths necessary to kill would almost certainly depend on the concentration of H2S.

We did have a tragic incident in the Shenandoah Valley a few years ago, in which several members of a farm family who were working in a manure pit were quickly overcome by H2S and killed.  Obviously, from this incident, a sufficiently high concentration is quickly lethal; what I don't know are the numbers for "sufficiently high" and "quidkly."

I have heard that one breath of hydrogen sulfide is fatal. Is there any documentation concerning this?

Thank you.
