Hydrogen Sulfide is extremely toxic.

[Inyo-Mono]

I have never heard of this gas, what is used for?

[Boogieman]

Isn’t that the stuff they add in small amounts to natural gas to give it the “rotten egg” smell so that you know when there is a gas leak?

[Getready]

At least as toxic as hydrogen cyanide. ...it is the smell of eggs...but our noses are very sensitive to it...so we can smell it as less than toxic levels...but if you smell it...GET OUTTA THERE PRONTO.

I highly doubt the newspaper reporter even knew what H2S was so they kept printing H2S instead of its more familiar name "Hydrogen Sulfide". Its often found in well because of the lack of oxygen under ground.

Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers;
