Why does the released air from inside an innertube smell

Whenever I release the air from inside an innertube it always carries the distinct smell of fish, why is this?
It's something that has puzzled me for years, since I was a nipper in fact.

A true scalp is not only overtaking someone but leaving them stopped at a set of lights. As you, who have clearly beaten the lights, pummels nothing but the open air ahead. ~ 'DondaddyD'. Player of the Unspoken Game

Not sure I'd buy any fish that smelt like innertubes.1985 Mercian King of Mercia - work in progress (Hah! Who am I kidding?)

It's the smell of rubber! That's what the inner tubes are made of.0

It smells a lot like an amide-based cross-linking agent we use in the lab to make chemicals polymerise in gels. Butyl rubber (as found in most inner-tubes) is made by polymerising nitrogen-containing hydrocarbons, I'd imagine it's left from the manufacturing process somewhere.

I love that smell!
Found out something weird and wonderful the other day though. You know that metallic smell from handling copper or brass? It's not the metal folks, it's you! Don't believe me? Sniff a piece of copper without touching it at all- nothing. Then handle it an smell your hands. True I promise.FCN 5 belt driven fixie for city bits

Its the smell of broken egos and crushed souls of all those you pass on the journey into work, it seeps into your tyres as a momento of your SCR victories. :P0

I love that smell, but yeah, it's just rubber, what ever connections rubber and fish build in your cortex would probably get bleeped out of a renamed Rihanna song.I used to just ride my bike to work but now I find myself going out looking for bigger and bigger hills.0

I must have missed something because I'm pretty sure they taught me at school that rubber comes from trees.

It's to do with the chemicals used during the vulcanising process.Unwashed (but well-lubricated) fixed thing, jeans, DMs - FCN 7(?)0

As someone who abhors fish (noting the French have the right name for it) and yet who loves the smell of inner tube gas in the mornings, I can assure you it does not smell of fish!

Sorry pbt150 but that explanation sounds a little far fetched to me, I'm going with the fart gas from a puffer fish theory.0 -
